General Description

The A29L160A is a 16Mbit, 3.3 volt-only Flash memory

organized as 2,097,152 bytes of 8 bits or 1,048,576 words of

16 bits each. The 8 bits of data appear on I/O0 - I/O7; the 16

bits of data appear on I/O⁰~I/O15. The A29L160A is offered in

48-ball FBGA, 44-pin SOP and 48-Pin TSOP packages. This

device is designed to be programmed in-system with the

standard system 3.3 volt VCC supply. Additional 12.0 volt

VPP is not required for in-system write or erase operations.

However, the A29L160A can also be programmed in

standard EPROM programmers.

The A29L160A has the first toggle bit, I/O⁶, which indicates

whether an Embedded Program or Erase is in progress, or it

is in the Erase Suspend. Besides the I/O6 toggle bit, the

A29L160A has a second toggle bit, I/O², to indicate whether

the addressed sector is being selected for erase. The

A29L160A also offers the ability to program in the Erase

Suspend mode. The standard A29L160A offers access times

of 70 and 90ns, allowing high-speed microprocessors to

operate without wait states. To eliminate bus contention the

device has separate chip enable (

), write enable (

)

WE

CE

and output enable (

) controls.

OE

The device requires only a single 3.3 volt power supply for

both read and write functions. Internally generated and

regulated voltages are provided for the program and erase

operations.

The A29L160A is entirely software command set compatible

with the JEDEC single-power-supply Flash standard.

Commands are written to the command register using

standard microprocessor write timings. Register contents

serve as input to an internal state-machine that controls the

erase and programming circuitry. Write cycles also internally

latch addresses and data needed for the programming and

erase operations. Reading data out of the device is similar to

reading from other Flash or EPROM devices.

Device programming occurs by writing the proper program

command sequence. This initiates the Embedded Program

algorithm - an internal algorithm that automatically times the

program pulse widths and verifies proper program margin.

Device erasure occurs by executing the proper erase

command sequence. This initiates the Embedded Erase

The hardware sector protection feature disables operations

for both program and erase in any combination of the

sectors of memory. This can be achieved via programming

equipment.

The Erase Suspend/Erase Resume feature enables the user

to put erase on hold for any period of time to read data from,

or program data to, any other sector that is not selected for

erasure. True background erase can thus be achieved.

-

an internal algorithm that automatically

preprograms the array (if it is not already programmed)

before executing the erase operation. During erase, the

device automatically times the erase pulse widths and

verifies proper erase margin. The Unlock Bypass mode

facilitates faster programming times by requiring only two

write cycles to program data instead of four.

Data

circuitry. A system reset would thus also reset the device,

enabling the system microprocessor to read the boot-up

firmware from the Flash memory.

The device offers two power-saving features. When

addresses have been stable for a specified amount of time,

the device enters the automatic sleep mode. The system can

also place the device into the standby mode. Power

consumption is greatly reduced in both these modes.

After a program or erase cycle has been completed, the

device is ready to read array data or accept another

command.

The sector erase architecture allows memory sectors to be

erased and reprogrammed without affecting the data

contents of other sectors. The A29L160A is fully erased

when shipped from the factory.

Sector Protection/Unprotection

Temporary Sector Unprotect

The hardware sector protection feature disables both

program and erase operations in any sector. The hardware

sector unprotection feature re-enables both program and

erase operations in previously protected sectors.

It is possible to determine whether a sector is protected or

unprotected. See “Autoselect Mode” for details.

This feature allows temporary unprotection of previous

protected sectors to change data in-system. The Sector

Unprotect mode is activated by setting the

pin to VID.

RESET

During this mode, formerly protected sectors can be

programmed or erased by selecting the sector addresses.

Once V^IDis removed from the

pin, all the previously

Sector protection / unprotection can be implemented via two

methods. The primary method requires VID on the

protected sectors are protected again. Figure 1 shows the

RESET

via programming equipment. Figure 2 shows the algorithm

and the Sector Protect / Unprotect Timing Diagram illustrates

the timing waveforms for this feature. This method uses

standard microprocessor bus cycle timing. For sector

unprotect, all unprotected sectors must first be protected

prior to the first sector unprotect write cycle. The alternate

method must be implemented using programming

equipment. The procedure requires a high voltage (V^ID) on

address pin A9 and the control pins.

START

The device is shipped with all sectors unprotected.

It is possible to determine whether a sector is protected or

Hardware Data Protection

The requirement of command unlocking sequence for

programming or erasing provides data protection against

inadvertent writes (refer to the Command Definitions table).

In addition, the following hardware data protection measures

prevent accidental erasure or programming, which might

otherwise be caused by spurious system level signals during

V^CCpower-up transitions, or from system noise. The device

Common Flash Memory Interface (CFI)

device is ready to read array data. The system can read CFI

information at the addresses given in Table 5-8. In word

mode, the upper address bits (A7-MSB) must be all zeros.

To terminate reading CFI data, the system must write the

reset command.

The system can also write the CFI query command when the

device is in the autoselect mode. The device enters the CFI

query mode, and the system can read CFI data at the

addresses given in Table 5-8. The system must write the

reset command to return the device to the autoselect mode.

The Common Flash Interface (CFI) specification outlines

device and host system software interrogation handshake,

which allows specific vendor-specified software algorithms to

be used for entire families of devices. Software support can

then be device-independent, JEDEC ID-independent, and

forward- and backward-compatible for the specified flash

device families. Flash vendors can standardize their existing

interface for long-term compatibility.

This device enters the CFI Query mode when the system

writes the CFI Query command, 98h, to address 55h in word

Command Definitions

Autoselect Command Sequence

Writing specific address and data commands or sequences

into the command register initiates device operations. The

Command Definitions table defines the valid register

command sequences. Writing incorrect address and data

values or writing them in the improper sequence resets the

device to reading array data.

The autoselect command sequence allows the host system to

access the manufacturer and devices codes, and determine

whether or not a sector is protected. The Command

Definitions table shows the address and data requirements.

This method is an alternative to that shown in the Autoselect

Codes (High Voltage Method) table, which is intended for

PROM programmers and requires V^IDon address bit A9.

The autoselect command sequence is initiated by writing two

unlock cycles, followed by the autoselect command. The

device then enters the autoselect mode, and the system may

read at any address any number of times, without initiating

another command sequence.

All addresses are latched on the falling edge of

or

,

CE

WE

whichever happens later. All data is latched on the rising

edge of or , whichever happens first. Refer to the

WE

CE

appropriate timing diagrams in the "AC Characteristics"

section.

A read cycle at address XX00h retrieves the manufacturer

code and another read cycle at XX11h retrieves the

continuation code. A read cycle at address XX01h returns the

device code. A read cycle containing a sector address (SA)

and the address 02h in returns 01h if that sector is protected,

or 00h if it is unprotected. Refer to the Sector Address tables

for valid sector addresses.

Reading Array Data

The device is automatically set to reading array data after

device power-up. No commands are required to retrieve

data. The device is also ready to read array data after

completing an Embedded Program or Embedded Erase

algorithm. After the device accepts an Erase Suspend

command, the device enters the Erase Suspend mode. The

system can read array data using the standard read timings,

except that if it reads at an address within erase-suspended

sectors, the device outputs status data. After completing a

programming operation in the Erase Suspend mode, the

system may once again read array data with the same

exception. See "Erase Suspend/Erase Resume Commands"

for more information on this mode.

The system must issue the reset command to re-enable the

device for reading array data if I/O⁵goes high, or while in the

autoselect mode. See the "Reset Command" section, next.

See also "Requirements for Reading Array Data" in the

"Device Bus Operations" section for more information. The

Read Operations table provides the read parameters, and

Read Operation Timings diagram shows the timing diagram.

The system must write the reset command to exit the

autoselect mode and return to reading array data.

Word/Byte Program Command Sequence

The system may program the device by word or byte,

depending on the state of the

pin. Programming is a

BYTE

four-bus-cycle operation. The program command sequence is

initiated by writing two unlock write cycles, followed by the

program set-up command. The program address and data are

written next, which in turn initiate the Embedded Program

algorithm. The system is not required to provide further

controls or timings. The device automatically provides

internally generated program pulses and verify the

programmed cell margin. Table 9 shows the address and data

requirements for the byte program command sequence.

When the Embedded Program algorithm is complete, the

device then returns to reading array data and addresses are

longer latched. The system can determine the status of the

Reset Command

Writing the reset command to the device resets the device to

reading array data. Address bits are don't care for this

command. The reset command may be written between the

sequence cycles in an erase command sequence before

erasing begins. This resets the device to reading array data.

Once erasure begins, however, the device ignores reset

commands until the operation is complete.

Any commands written to the device during the Embedded

Program Algorithm are ignored. Note that a hardware reset

immediately terminates the programming operation. The Byte

Program command sequence should be reinitiated once the

device has reset to reading array data, to ensure data

integrity.

Programming is allowed in any sequence and across sector

boundaries. A bit cannot be programmed from a “0” back to a

“1”. Attempting to do so may halt the operation and set I/O5 to

Chip Erase Command Sequence

Sequence

Chip erase is a six-bus-cycle operation. The chip erase

command sequence is initiated by writing two unlock cycles,

followed by a set-up command. Two additional unlock write

cycles are then followed by the chip erase command, which

in turn invokes the Embedded Erase algorithm. The device

does not require the system to preprogram prior to erase. The

Embedded Erase algorithm automatically preprograms and

verifies the entire memory for an all zero data pattern prior to

electrical erase. The system is not required to provide any

controls or timings during these operations. The Command

Definitions table shows the address and data requirements

for the chip erase command sequence.

Any commands written to the chip during the Embedded

Erase algorithm are ignored. The system can determine the

status of the erase operation by using I/O⁷, I/O6, or I/O2. See

Completed

Sector Erase Command Sequence

Sector erase is a six-bus-cycle operation. The sector erase

command sequence is initiated by writing two unlock cycles,

followed by a set-up command. Two additional unlock write

cycles are then followed by the address of the sector to be

erased, and the sector erase command. The Command

Definitions table shows the address and data requirements

for the sector erase command sequence.

The device does not require the system to preprogram the

memory prior to erase. The Embedded Erase algorithm

automatically programs and verifies the sector for an all zero

data pattern prior to electrical erase. The system is not

required to provide any controls or timings during these

operations.

After the command sequence is written, a sector erase time-

out of 50µs begins. During the time-out period, additional

sector addresses and sector erase commands may be

written. Loading the sector erase buffer may be done in any

sequence, and the number of sectors may be from one sector

to all sectors. The time between these additional cycles must

be less than 50µs, otherwise the last address and command

might not be accepted, and erasure may begin. It is

recommended that processor interrupts be disabled during

this time to ensure all commands are accepted. The

interrupts can be re-enabled after the last Sector Erase

command is written. If the time between additional sector

erase commands can be assumed to be less than 50µs, the

system need not monitor I/O³. Any command other than

Sector Erase or Erase Suspend during the time-out period

resets the device to reading array data. The system must

rewrite the command sequence and any additional sector

addresses and commands.

Note : See the appropriate Command Definitions table for

program command sequence.

Figure 3. Program Operation

Unlock Bypass Command Sequence

The unlock bypass feature allows the system to program

bytes or words to the device faster than using the standard

program command sequence. The unlock bypass command

sequence is initiated by first writing two unlock cycles. This is

followed by a third write cycle containing the unlock bypass

command, 20h. The device then enters the unlock bypass

mode.

A two-cycle unlock bypass program command

sequence is all that is required to program in this mode. The

first cycle in this sequence contains the unlock bypass

program command, A0h; the second cycle contains the

program address and data. Additional data is programmed in

the same manner. This mode dispenses with the initial two

unlock cycles required in the standard program command

sequence, resulting in faster total programming time. Table 9

shows the requirements for the command sequence.

During the unlock bypass mode, only the Unlock Bypass

Program and Unlock Bypass Reset commands are valid. To

exit the unlock bypass mode, the system must issue the two-

cycle unlock bypass reset command sequence. The first

cycle must contain the data 90h; the second cycle the data

Once the sector erase operation has begun, only the Erase

When the Embedded Erase algorithm is complete, the device

returns to reading array data and addresses are no longer

operation by using I/O⁷, I/O6, or I/O2. Refer to "Write

Erase Suspend/Erase Resume Commands

The Erase Suspend command allows the system to interrupt

a sector erase operation and then read data from, or

program data to, any sector not selected for erasure. This

command is valid only during the sector erase operation,

including the 50µs time-out period during the sector erase

command sequence. The Erase Suspend command is

ignored if written during the chip erase operation or

Embedded Program algorithm. Writing the Erase Suspend

command during the Sector Erase time-out immediately

terminates the time-out period and suspends the erase

operation. Addresses are "don't cares" when writing the

Erase Suspend command.

When the Erase Suspend command is written during a

20µs to suspend the erase operation. However, when the

Erase Suspend command is written during the sector erase

time-out, the device immediately terminates the time-out

period and suspends the erase operation.

Yes

Erasure Completed

After the erase operation has been suspended, the system

can read array data from or program data to any sector not

selected for erasure. (The device "erase suspends" all

sectors selected for erasure.) Normal read and write timings

and command definitions apply. Reading at any address

within erase-suspended sectors produces status data on I/O⁷

- I/O0. The system can use I/O7, or I/O6 and I/O2 together, to

determine if a sector is actively erasing or is erase-

suspended. See "Write Operation Status" for information on

these status bits.

Note :

1. See the appropriate Command Definitions table for erase

command sequences.

2. See "I/O

: Sector Erase Timer" for more information.

Figure 4. Erase Operation

After an erase-suspended program operation is complete,

the system can once again read array data within non-

suspended sectors. The system can determine the status of

the program operation using the I/O⁷or I/O6 status bits, just

as in the standard program operation. See "Write Operation

Status" for more information.

The system may also write the autoselect command

sequence when the device is in the Erase Suspend mode.

The device allows reading autoselect codes even at

addresses within erasing sectors, since the codes are not

stored in the memory array. When the device exits the

autoselect mode, the device reverts to the Erase Suspend

mode, and is ready for another valid operation. See

"Autoselect Command Sequence" for more information.

may be read at any address, and is valid after the rising edge

Reading Toggle Bits I/O6, I/O2

Refer to Figure 6 for the following discussion. Whenever the

system initially begins reading toggle bit status, it must read

I/O7 - I/O0 at least twice in a row to determine whether a

toggle bit is toggling. Typically, a system would note and store

the value of the toggle bit after the first read. After the second

read, the system would compare the new value of the toggle

bit with the first. If the toggle bit is not toggling, the device has

completed the program or erase operation. The system can

read array data on I/O⁷- I/O0 on the following read cycle.

However, if after the initial two read cycles, the system

determines that the toggle bit is still toggling, the system also

should note whether the value of I/O⁵is high (see the section

on I/O⁵). If it is, the system should then determine again

whether the toggle bit is toggling, since the toggle bit may

have stopped toggling just as I/O⁵went high. If the toggle bit

is no longer toggling, the device has successfully completed

the program or erase operation. If it is still toggling, the device

did not complete the operation successfully, and the system

must write the reset command to return to reading array data.

The remaining scenario is that the system initially determines

that the toggle bit is toggling and I/O⁵has not gone high. The

system may continue to monitor the toggle bit and I/O⁵

through successive read cycles, determining the status as

described in the previous paragraph. Alternatively, it may

choose to perform other system tasks. In this case, the

system must start at the beginning of the algorithm when it

returns to determine the status of the operation (top of Figure

6).

pulse in the command sequence (prior to the

During an Embedded Program or Erase algorithm operation,

successive read cycles to any address cause I/O⁶to toggle.

(The system may use either

cycles.) When the operation is complete, I/O6 stops toggling.

After an erase command sequence is written, if all sectors

selected for erasing are protected, I/O6 toggles for

approximately 100µs, then returns to reading array data. If not

all selected sectors are protected, the Embedded Erase

algorithm erases the unprotected sectors, and ignores the

selected sectors that are protected.

The system can use I/O⁶and I/O2 together to determine

whether a sector is actively erasing or is erase-suspended.

When the device is actively erasing (that is, the Embedded

Erase algorithm is in progress), I/O⁶toggles. When the device

enters the Erase Suspend mode, I/O⁶stops toggling.

However, the system must also use I/O²to determine which

sectors are erasing or erase-suspended. Alternatively, the

system can use I/O⁷(see the subsection on " I/O7 :

Polling").

Data

If a program address falls within a protected sector, I/O⁶

toggles for approximately 2µs after the program command

sequence is written, then returns to reading array data.

I/O⁶also toggles during the erase-suspend-program mode,

and stops toggling once the Embedded Program algorithm is

complete.

graphical form. See also the subsection on " I/O²: Toggle Bit

I/O5: Exceeded Timing Limits

I/O5 indicates whether the program or erase time has

exceeded a specified internal pulse count limit. Under these

conditions I/O5 produces a "1." This is a failure condition that

indicates the program or erase cycle was not successfully

completed.

The I/O⁵failure condition may appear if the system tries to

program a "1 "to a location that is previously programmed to

may read I/O³to determine whether or not an erase

operation has begun. (The sector erase timer does not apply

to the chip erase command.) If additional sectors are

selected for erasure, the entire time-out also applies after

each additional sector erase command. When the time-out is

complete, I/O³switches from "0" to "1." The system may

ignore I/O³if the system can guarantee that the time

between additional sector erase commands will always be

Notes:

1. Typical program and erase times assume the following conditions: 25°C, 3.0V VCC, 10,000 cycles. Additionally, programming

typically assumes checkerboard pattern.

2. Under worst case conditions of 90°C, VCC = 3.0V, 100,000 cycles.

3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes

program faster than the maximum byte program time listed. If the maximum byte program time given is exceeded, only then

does the device set I/O⁵= 1. See the section on I/O5 for further information.

4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.

5. System-level overhead is the time required to execute the four-bus-cycle command sequence for programming. See Table 9

for further information on command definitions.

6. The device has a guaranteed minimum erase and program cycle endurance of 10,000 cycles.
