Overview  
Cypress Semiconductor Corporation’s EZ-USB® NX2LP-Flex  
(CY7C68033/CY7C68034) is a firmware-based, programmable  
version of the EZ-USB NX2LP(CY7C68023/CY7C68024),  
which is a fixed-function, low power USB 2.0 NAND Flash  
controller. By integrating the USB 2.0 transceiver, serial interface  
engine (SIE), enhanced 8051 microcontroller, and a program-  
mable peripheral interface in a single chip, Cypress has created  
a very cost-effective solution that enables feature-rich NAND  
Flash-based applications.

I/O  
The ingenious architecture of NX2LP-Flex results in USB data  
transfer rates of over 53 Mbytes per second, the maximum  
allowable USB 2.0 bandwidth, while still using a low cost 8051  
microcontroller in a small 56-pin QFN package. Because it  
incorporates the USB 2.0 transceiver, the NX2LP-Flex is more  
economical, providing a smaller footprint solution than external  
USB 2.0 SIE or transceiver implementations. With EZ-USB  
NX2LP-Flex, the Cypress Smart SIE handles most of the USB  
1.1 and 2.0 protocol, freeing the embedded microcontroller for  
application-specific functions and decreasing development time  
while ensuring USB compatibility.

8051 Microprocessor  
The 8051 microprocessor embedded in the NX2LP-Flex has  
256 bytes of register RAM, an expanded interrupt system and  
three timer/counters.

8051 Clock Frequency  
Special Function Registers  
NX2LP-Flex has an on-chip oscillator circuit that uses an  
external 24 MHz (±100 ppm) crystal with the following  
characteristics:  
Certain 8051 SFR addresses are populated to provide fast  
access to critical NX2LP-Flex functions. These SFR additions  
are shown in Table 1 on page 6. Bold type indicates  
non-standard, enhanced 8051 registers. The two SFR rows that  
end with ‘0’ and ‘8’ contain bit-addressable registers. The four I/O  
ports A–D use the SFR addresses used in the standard 8051 for  
ports 0–3, which are not implemented in NX2LP-Flex. Because  
of the faster and more efficient SFR addressing, the NX2LP-Flex  
I/O ports are not addressable in external RAM space (using the  
MOVX instruction).

An on-chip PLL multiplies the 24-MHz oscillator up to 480 MHz,  
as required by the transceiver/PHY, and internal counters divide  
it down for use as the 8051 clock. The default 8051 clock  
frequency is 12 MHz. The clock frequency of the 8051 can be  
changed by the 8051 through the CPUCS register, dynamically

I C Bus  
NX2LP supports the I2C bus as a master only at 100/400 kHz.  
SCL and SDA pins have open-drain outputs and hysteresis  
inputs. These signals must be pulled up to 3.3 V, even if no I2C  
device is connected. The I2C bus is disabled at startup and only  
available for use after the initial NAND access.

Buses  
The NX2LP-Flex features an 8- or 16-bit ‘FIFO’ bidirectional data bus, multiplexed on I/O ports B and D.  
The default firmware image implements an 8-bit data bus in GPIF master mode. It is recommended that additional interfaces added  
to the default firmware image use this 8-bit data bus.  
Enumeration  
During the startup sequence, internal logic checks for the presence of NAND Flash with valid firmware. If valid firmware is found, the  
NX2LP-Flex loads it and operates according to the firmware. If no NAND Flash is detected, or if no valid firmware is found, the  
NX2LP-Flex uses the default values from internal ROM space for manufacturing mode operation. The two modes of operation are  
described in the section Normal Operation Mode on page 7 and Manufacturing Mode on page 7.

Figure 4. NX2LP-Flex Enumeration Sequence  
Default Silicon ID Values  
To facilitate proper USB enumeration when no programmed  
NAND Flash is present, the NX2LP-Flex has default silicon ID  
values stored in ROM space. The default silicon ID values should  
only be used for development purposes. Designers must use  
their own Vendor ID for final products. A Vendor ID is obtained  
through registration with the USB Implementor’s Forum  
(USB-IF). If the NX2LP-Flex is used as a mass storage class  
device, a unique USB serial number is required for each device  
to comply with the USB Mass Storage class specification.

Interrupt System

Mode  
INT2 Interrupt Request and Enable Registers  
NX2LP-Flex implements an autovector feature for INT2 and  
INT4. There are 27 INT2 (USB) vectors and 14 INT4  
(FIFO/GPIF) vectors. For more details, refer to the EZ-USB  
Technical Reference Manual (TRM).  
Normal Operation Mode  
In normal operation mode, the NX2LP-Flex behaves as a  
USB 2.0 Mass Storage Class NAND Flash controller. This  
includes all typical USB device states (powered, configured, and  
so on). The USB descriptors are returned according to the data  
stored in the configuration data memory area. Normal read and  
write access to the NAND Flash is available in this mode.  
USB-Interrupt Autovectors  
The main USB interrupt is shared by 27 interrupt sources. To  
save the code and processing time normally required to identify  
the individual USB interrupt source, the NX2LP-Flex provides a  
second level of interrupt vectoring, called Autovectoring. When  
a USB interrupt is asserted, the NX2LP-Flex pushes the program  
counter to its stack and then jumps to address 0x0500; it expects  
to find a ‘jump’ instruction to the USB Interrupt service routine  
here.  
Manufacturing Mode  
In manufacturing mode, the NX2LP-Flex enumerates using the  
default descriptors and configuration data that are stored in  
internal ROM space. This mode enables for first time  
programming of the configuration data memory area, and board  
level manufacturing tests.  
Developers familiar with Cypress’s programmable USB devices  
should note that these interrupt vector values differ from those  
used in other EZ-USB microcontrollers. This is due to the  
additional NAND boot logic that is present in the NX2LP-Flex  
ROM space. Also, these values are fixed and cannot be changed  
in the firmware.

If autovectoring is enabled (AV2EN = 1 in the INTSET-UP register), the NX2LP-Flex substitutes its INT2VEC byte. Therefore, if the  
high byte (‘page’) of a jump-table address is preloaded at location 0x544, the automatically inserted INT2VEC byte at 0x545 directs  
the jump to the correct address out of the 27 addresses within the page.  
FIFO/GPIF Interrupt (INT4)  
Just as the USB Interrupt is shared among 27 individual USB-interrupt sources, the FIFO/GPIF interrupt is shared among 14 individual  
FIFO/GPIF sources. The FIFO/GPIF Interrupt, such as the USB Interrupt, can employ autovectoring. Table 4 on page 9 shows the  
priority and INT4VEC values for the 14 FIFO/GPIF interrupt sources.

If autovectoring is enabled (AV4EN = 1 in the INTSET-UP  
register), the NX2LP-Flex substitutes its INT4VEC byte.  
Therefore, if the high byte (‘page’) of a jump-table address is  
preloaded at location 0x554, the automatically inserted  
INT4VEC byte at 0x555 directs the jump to the correct address  
out of the 14 addresses within the page. When the ISR occurs,  
the NX2LP-Flex pushes the program counter to its stack and  
then jumps to address 0x553; it expects to find a ‘jump’  
instruction to the ISR Interrupt service routine here.  
used as the clock source for the NX2LP-Flex, the reset period  
must enable the stabilization of the crystal and the PLL. This  
reset period should be approximately 5 ms after VCC has  
reached 3.0V. If the crystal input pin is driven by a clock signal,  
the internal PLL stabilizes in 200 s after VCC has reached  
3.0 V[1]. Figure 5 shows a POR condition and a reset applied  
during operation. A POR is defined as the time reset is asserted  
while power is being applied to the circuit. A powered reset is  
defined to be when the NX2LP-Flex has previously been  
powered on and operating and the RESET# pin is asserted.  
Reset and Wakeup  
For more information on power on reset implementation for the  
EZ-USB family of products, refer to the application note  
EZ-USB FX2™/AT2™/SX2™.

The 8051 puts itself and the rest of the chip into a power down  
mode by setting PCON.0 = 1. This stops the oscillator and PLL.  
When WAKEUP is asserted by external logic, the oscillator  
restarts, after the PLL stabilizes, and then the 8051 receives a  
wakeup interrupt. This applies whether or not NX2LP-Flex is  
connected to the USB.

Setup Data Buffer  
Endpoint RAM  
A separate 8-byte buffer at 0xE6B8-0xE6BF holds the setup data  
from a CONTROL transfer.  
Size  
3 × 64 bytes  
(Endpoints 0 and 1)  
Endpoint Configurations (High Speed Mode)  
8 × 512 bytes (Endpoints 2, 4, 6, 8)  
Endpoints 0 and 1 are the same for every configuration. Endpoint  
0 is the only control endpoint, and endpoint 1 can be either bulk  
or interrupt. The endpoint buffers can be configured in any 1 of  
the 12 configurations shown in the vertical columns. When  
operating in full speed bulk mode, only the first 64 bytes of each  
buffer are used. For example, in high speed the max packet size  
is 512 bytes, but in full speed it is 64 bytes. Even though a buffer  
is configured to be a 512 byte buffer, in full speed only the first  
64 bytes are used. The unused endpoint buffer space is not  
available for other operations. The following is an example  
endpoint configuration:  
Organization  
EP0  
Bidirectional endpoint zero, 64-byte buffer  
EP1IN, EP1OUT  
64-byte buffers, bulk or interrupt  
EP2, 4, 6, 8  
Eight 512-byte buffers, bulk, interrupt, or isochronous.  
EP4 and EP8 can be double buffered, while EP2 and 6 can  
be either double, triple, or quad buffered.  
EP2–1024 double buffered; EP6–512 quad buffered (column 8  
in Figure 8).

same configuration to implement 100-ns timing on the NAND bus  
to support proper detection of all NAND Flash types.  
External FIFO Interface  
Architecture  
GPIF  
The NX2LP-Flex slave FIFO architecture has eight 512-byte  
blocks in the endpoint RAM that directly serve as FIFO  
memories, and are controlled by FIFO control signals (such as  
SLCS#, SLRD, SLWR, SLOE, PKTEND, and flags).  
The GPIF is a flexible 8- or 16-bit parallel interface driven by a  
user-programmable finite state machine. It enables the  
NX2LP-Flex to perform local bus mastering and can implement  
a wide variety of protocols such as 8-bit NAND interface, printer  
parallel port, and Utopia. The default NAND firmware and boot  
logic uses GPIF functionality to interface with NAND Flash.  
In operation, some of the eight RAM blocks fill or empty from the  
SIE, while the others are connected to the I/O transfer logic. The  
transfer logic takes two forms: the GPIF for internally generated  
control signals or the slave FIFO interface for externally  
controlled transfers.  
The GPIF on the NX2LP-Flex features three programmable  
control outputs (CTL) and two general purpose ready inputs  
(RDY). The GPIF data bus width can be 8 or 16 bits. Because  
the default NAND firmware image implements an 8-bit data bus  
and up to eight chip enable pins on the GPIF ports, it is  
recommended that designs based upon the default firmware  
image also use an 8-bit data bus.  
Master/Slave Control Signals  
The NX2LP-Flex endpoint FIFOS are implemented as eight  
physically distinct 256 × 16 RAM blocks. The 8051/SIE can  
switch any of the RAM blocks between two domains, the USB  
(SIE) domain and the 8051-I/O Unit domain. This switching is  
done virtually instantaneously, giving essentially zero transfer  
time between ‘USB FIFOS’ and ‘Slave FIFOS’. Since they are  
physically the same memory, no bytes are actually transferred  
between buffers.  
Each GPIF vector defines the state of the control outputs and  
determines what state a ready input (or multiple inputs) must be  
before proceeding. The GPIF vector can be programmed to  
advance a FIFO to the next data value, advance an address, and  
so on. A sequence of the GPIF vectors make up a single  
waveform that is executed to perform the desired data move  
between the NX2LP-Flex and the external device.  
At any time, some RAM blocks are filling/emptying with USB data  
under SIE control, while other RAM blocks are available to the  
8051 and/or the I/O control unit. The RAM blocks operate as  
single-port in the USB domain and dual-port in the 8051-I/O  
domain. The blocks can be configured as single, double, triple,  
or quad buffered as previously shown.  
Three Control OUT Signals  
The NX2LP-Flex exposes three control signals, CTL[2:0]. CTLx  
waveform edges can be programmed to make transitions as fast  
as once per clock (20.8 ns using a 48 MHz clock).  
The I/O control unit implements either an internal-master (M for  
master) or external-master (S for Slave) interface.  
Two Ready IN Signals  
In master (M) mode, the GPIF internally controls FIFOADR[1:0]  
to select a FIFO. The two RDY pins can be used as flag inputs  
from an external FIFO or other logic if desired. The GPIF can be  
run from an internally derived clock (IFCLK), at a rate that  
transfers data up to 96 Megabytes/s (48 MHz IFCLK with 16-bit  
interface).  
The 8051 programs the GPIF unit to test the RDY pins for GPIF  
branching. The 56-pin package brings out two signals, RDY[1:0].  
Long Transfer Mode  
In GPIF master mode, the 8051 appropriately sets GPIF  
transaction count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1,  
or GPIFTCB0) for unattended transfers of up to 232 transactions.  
The GPIF automatically throttles data flow to prevent underflow  
or overflow until the full number of requested transactions  
complete. The GPIF decrements the value in these registers to  
represent the current status of the transaction.  
In slave (S) mode, the NX2LP-Flex accepts an internally derived  
clock (IFCLK, max. frequency 48 MHz) and SLCS#, SLRD,  
SLWR, SLOE, PKTEND signals from external logic. Each  
endpoint can individually be selected for byte or word operation  
by an internal configuration bit and a Slave FIFO output enable  
signal SLOE enables data of the selected width. External logic  
must ensure that the output enable signal is inactive when writing  
data to a slave FIFO. The slave interface must operate  
asynchronously, where the SLRD and SLWR signals act directly  
as strobes, rather than a clock qualifier as in a synchronous  
mode. The signals SLRD, SLWR, SLOE and PKTEND are gated  
by the signal SLCS#.  
ECC Generation[5]  
The NX2LP-Flex can calculate error correcting codes (ECCs) on  
data that passes across its GPIF or slave FIFO interfaces. There  
are two ECC configurations:  
Two ECCs, each calculated over 256 bytes (SmartMedia  
Standard)  
GPIF and FIFO Clock Rates  
One ECC calculated over 512 bytes.  
An 8051 register bit selects one of two frequencies for the  
internally supplied interface clock: 30 MHz and 48 MHz. A bit  
within the IFCONFIG register inverts the IFCLK signal.  
The following two ECC configurations are selected by the ECCM  
bit. The ECC can correct any one-bit error or detect any two-bit  
error.  
The default NAND firmware image implements a 48 MHz  
internally supplied interface clock. The NAND boot logic uses the  
Note  
5. To use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation.  
Document Number: 001-04247 Rev. *J  
Page 13 of 40  
CY7C68033/CY7C68034  
ECCM = 0  
Autopointer Access  
Two 3-byte ECCs, each calculated over a 256-byte block of data.  
This configuration conforms to the SmartMedia Standard and is  
used by both the NAND boot logic and default NAND firmware  
image.  
NX2LP-Flex provides two identical autopointers. They are  
similar to the internal 8051 data pointers, but with an additional  
feature: they can optionally increment after every memory  
access. Also, the autopointers can point to any NX2LP-Flex  
register or endpoint buffer space.  
When any value is written to ECCRESET and data is then  
passed across the GPIF or slave FIFO interface, the ECC for the  
first 256 bytes of data is calculated and stored in ECC1. The ECC  
for the next 256 bytes of data is stored in ECC2. After the second  
ECC is calculated, the values in the ECCx registers do not  
change until ECCRESET is written again, even if more data is  
subsequently passed across the interface.  
2
I C Controller  
NX2LP has one I2C port that the 8051, once running uses to  
control external I2C devices. The I2C port operates in master  
mode only. The I2C post is disabled at startup and only available  
for use after the initial NAND access.  
ECCM = 1  
I2C Port Pins  
One 3-byte ECC calculated over a 512-byte block of data.  
The I2C pins SCL and SDA must have external 2.2-kpull up  
resistors even if no EEPROM is connected to the NX2LP.  
When any value is written to ECCRESET and data is then  
passed across the GPIF or slave FIFO interface, the ECC for the  
first 512 bytes of data is calculated and stored in ECC1; ECC2  
is unused. After the ECC is calculated, the value in ECC1 does  
not change until ECCRESET is written again, even if more data  
is subsequently passed across the interface  
I2C Interface General-Purpose Access  
The 8051 can control peripherals connected to the I2C bus using  
the I2CTL and I2DATA registers. NX2LP provides I2C master  
control only and is never an I2C slave.

Master mode. The signals on the left edge of the ‘Port’ column  
are common to all modes of the NX2LP-Flex. The 8051 selects  
the interface mode using the IFCONFIG[1:0] register bits. Port  
mode is the power-on default configuration.

Figure 17 shows the timing relationship of the SLAVE FIFO  
signals during an asynchronous FIFO read. It shows a single  
read followed by a burst read.  
The data that is driven, after asserting SLRD, is the updated  
data from the FIFO. This data is valid after a propagation delay  
of tXFD from the activating edge of SLRD. In Figure 17, data N  
is the first valid data read from the FIFO. For data to appear on  
the data bus during the read cycle (that is SLRD is asserted),  
SLOE MUST be in an asserted state. SLRD and SLOE can  
also be tied together.  
At t = 0 the FIFO address is stable and the SLCS signal is  
asserted.  
At t = 1, SLOE is asserted. This results in the data bus being  
driven. The data that is driven on to the bus is previous data,  
it data that was in the FIFO from a prior read cycle.  
The same sequence of events is also shown for a burst read  
marked with T = 0 through 5.  
At t = 2, SLRD is asserted. The SLRD must meet the minimum  
active pulse of tRDpwl and minimum deactive pulse width of  
Note In burst read mode, during SLOE is assertion, the data bus  
is in a driven state and outputs the previous data. After SLRD is  
asserted, the data from the FIFO is driven on the data bus (SLOE  
must also be asserted) and then the FIFO pointer is  
incremented.  
t

SLRD or before SLRD is asserted (that is the SLCS and SLRD  
signals must both be asserted to start a valid read condition).

PKTEND  
Figure 19 shows the timing relationship of the SLAVE FIFO write  
in an asynchronous mode. The diagram shows a single write  
followed by a burst write of three bytes and committing the  
4-byte-short packet using PKTEND.  
The FIFO flag is also updated after tXFLG from the deasserting  
edge of SLWR.  
The same sequence of events are shown for a burst write and is  
indicated by the timing marks of T = 0 through 5.  
At t = 0 the FIFO address is applied, insuring that it meets the  
setup time of tSFA. If SLCS is used, it must also be asserted  
(SLCS may be tied low in some applications).  
Note In the burst write mode, after SLWR is deasserted, the data  
is written to the FIFO and then the FIFO pointer is incremented  
to the next byte in the FIFO. The FIFO pointer is post  
incremented.  
At t = 1 SLWR is asserted. SLWR must meet the minimum  
active pulse of tWRpwl and minimum de-active pulse width of  
tWRpwh. If the SLCS is used, it must be in asserted with SLWR  
or before SLWR is asserted.  
As shown in Figure 19 after the four bytes are written to the FIFO  
and SLWR is deasserted, the short 4-byte packet can be  
committed to the host using the PKTEND. The external device  
should be designed to not assert SLWR and the PKTEND signal  
at the same time. It should be designed to assert the PKTEND  
after SLWR is deasserted and met the minimum de-asserted  
pulse width. The FIFOADDR lines are to be held constant during  
the PKTEND assertion.  
At t = 2, data must be present on the bus tSFD before the  
deasserting edge of SLWR.  
At t = 3, deasserting SLWR causes the data to be written from  
the data bus to the FIFO and then increments the FIFO pointer.

28. Dashed lines denote signals with programmable polarity.

PCB Layout Recommendations  
Quad Flat Package No Leads (QFN) Package  
Design Notes  
[29]  
Follow these recommendations  
performance operation:  
to ensure reliable high  
Electrical contact of the part to the printed circuit board (PCB) is  
made by soldering the leads on the bottom surface of the  
package to the PCB. Therefore, special attention is required to  
the heat transfer area below the package to provide a good  
thermal bond to the circuit board. Design a copper (Cu) fill into  
the PCB as a thermal pad under the package. Heat is transferred  
from the NX2LP-Flex to the PCB through the device’s metal  
paddle on the bottom side of the package. It is then conducted  
from the PCB’s thermal pad to the inner ground plane by a  
5 × 5 array of vias. A via is a plated through hole in the PCB with  
a finished diameter of 13 mil. The QFN’s metal die paddle must  
be soldered to the PCB’s thermal pad. Solder mask is placed on  
the board top side over each via to resist solder flow into the via.  
The mask on the top side also minimizes outgassing during the  
solder reflow process.  
At least  
recommended to maintain signal quality.  
a four-layer impedance controlled boards is  
Specify impedance targets (ask your board vendor what they  
can achieve) to meet USB specifications.  
To control impedance, maintain trace widths and trace spacing.  
Minimize any stubs to avoid reflected signals.  
Connections between the USB connector shell and signal  
ground must be done near the USB connector.  
Bypass/flyback caps on VBUS, near connector, are  
recommended.  
DPLUS and DMINUS trace lengths should be kept to within  
2 mm of each other in length, with preferred length of  
20–30 mm.  
For further information on this package design, refer to the  
application note Application Note for Surface Mount Assembly of  
Amkor’s Eutectic and Lead-Free CSPnl™ Wafer Level Chip  
Scale Packages. This application note provides detailed  
information on board mounting guidelines, soldering flow, rework  
process, and so on.  
Maintain a solid ground plane under the DPLUS and DMINUS  
traces. Do not allow the plane to be split under these traces.  
No vias should be placed on the DPLUS or DMINUS trace  
routing unless absolutely necessary.  
Isolate the DPLUS and DMINUS traces from all other signal  
traces as much as possible.

Figure 21 displays a cross-sectional area underneath the package. The cross section is of only one via. The solder paste template  
needs to be designed to enable at least 50% solder coverage. The thickness of the solder paste template should be 5 mil. It is  
recommended that ‘No Clean’ type 3 solder paste is used for mounting the part. Nitrogen purge is recommended during reflow.  
Figure 22 is a plot of the solder mask pattern and Figure 23 displays an X-Ray image of the assembly (darker areas indicate solder).
