1408H–PLD–7/05
Description
The ATF1508ASV(L) is a high-performance, high-density complex programmable logic
device (CPLD) that utilizes Atmel’s proven electrically-erasable technology. With 128
logic macrocells and up to 100 inputs, it easily integrates logic from several TTL, SSI,
MSI, LSI and classic PLDs. The ATF1508ASV(L)’s enhanced routing switch matrices
increase usable gate count and increase odds of successful pin-locked design
modifications.
The ATF1508ASV(L) has up to 96 bi-directional I/O pins and four dedicated input pins,
depending on the type of device package selected. Each dedicated pin can also serve
as a global control signal, register clock, register reset or output enable. Each of these
control signals can be selected for use individually within each macrocell.
Each of the 128 macrocells generates a buried feedback that goes to the global bus.
Each input and I/O pin also feeds into the global bus. The switch matrix in each logic
block then selects 40 individual signals from the global bus. Each macrocell also gener-
ates a foldback logic term that goes to a regional bus. Cascade logic between
macrocells in the ATF1508ASV(L) allows fast, efficient generation of complex logic func-
tions. The ATF1508ASV(L) contains eight such logic chains, each capable of creating
sum term logic with a fan-in of up to 40 product terms.
The ATF1508ASV(L) macrocell, shown in Figure 1, is flexible enough to support highly-
complex logic functions operating at high-speed. The macrocell consists of five sections:
product terms and product term select multiplexer, OR/XOR/CASCADE logic, a flip-flop,
output select and enable, and logic array inputs.
Unused macrocells are automatically disabled by the compiler to decrease power con-
sumption. A security fuse, when programmed, protects the contents of the
ATF1508ASV(L). Two bytes (16 bits) of User Signature are accessible to the user for
purposes such as storing project name, part number, revision or date. The User Signa-
ture is accessible regardless of the state of the security fuse.
The ATF1508ASV(L) device is an in-system programmable (ISP) device. It uses the
industry-standard 4-pin JTAG interface (IEEE Std. 1149.1), and is fully-compliant with
JTAG’s Boundary-scan Description Language (BSDL). ISP allows the device to be pro-
grammed without removing it from the printed circuit board. In addition to simplifying the
manufacturing flow, ISP also allows design modifications to be made in the field via
software.
Product Terms and Select
Mux
Each ATF1508ASV(L) macrocell has five product terms. Each product term receives as
its inputs all signals from both the global bus and regional bus.
The product term select multiplexer (PTMUX) allocates the five product terms as
needed to the macrocell logic gates and control signals. The PTMUX programming is
determined by the design compiler, which selects the optimum macrocell configuration.
OR/XOR/CASCADE Logic
The ATF1508ASV(L)’s logic structure is designed to efficiently support all types of logic.
Within a single macrocell, all the product terms can be routed to the OR gate, creating a
5-input AND/OR sum term. With the addition of the CASIN from neighboring macrocells,
this can be expanded to as many as 40 product terms with little additional delay.
The macrocell’s XOR gate allows efficient implementation of compare and arithmetic
functions. One input to the XOR comes from the OR sum term. The other XOR input can
be a product term or a fixed high- or low-level. For combinatorial outputs, the fixed level
input allows polarity selection. For registered functions, the fixed levels allow DeMorgan
minimization of product terms. The XOR gate is also used to emulate T- and JK-type
flip-flops.

1408H–PLD–7/05
ATF1508ASV(L)
Flip-flop
The ATF1508ASV(L)’s flip-flop has very flexible data and control functions. The data
input can come from either the XOR gate, from a separate product term or directly from
the I/O pin. Selecting the separate product term allows creation of a buried registered
feedback within a combinatorial output macrocell. (This feature is automatically imple-
mented by the fitter software). In addition to D, T, JK and SR operation, the flip-flop can
also be configured as a flow-through latch. In this mode, data passes through when the
clock is high and is latched when the clock is low.
The clock itself can either be the Global CLK Signal (GCK) or an individual product term.
The flip-flop changes state on the clock's rising edge. When the GCK signal is used as
the clock, one of the macrocell product terms can be selected as a clock enable. When
the clock enable function is active and the enable signal (product term) is low, all clock
edges are ignored. The flip-flop’s asynchronous reset signal (AR) can be either the Glo-
bal Clear (GCLEAR), a product term, or always off. AR can also be a logic OR of
GCLEAR with a product term. The asynchronous preset (AP) can be a product term or
always off.

Extra Feedback
I/O Control
The ATF15xxSE Family macrocell output can be selected as registered or combinato-
rial. The extra buried feedback signal can be either combinatorial or a registered signal
regardless of whether the output is combinatorial or registered. (This enhancement
function is automatically implemented by the fitter software.) Feedback of a buried com-
binatorial output allows the creation of a second latch within a macrocell.
The output enable multiplexer (MOE) controls the output enable signal. Each I/O can be
individually configured as an input, output or for bi-directional operation. The output
enable for each macrocell can be selected from the true or compliment of the two output
enable pins, a subset of the I/O pins, or a subset of the I/O macrocells. This selection is
automatically done by the fitter software when the I/O is configured as an input, all mac-
rocell resources are still available, including the buried feedback, expander and cascade
logic.
Global Bus/Switch Matrix
Foldback Bus
The global bus contains all input and I/O pin signals as well as the buried feedback sig-
nal from all 128 macrocells. The switch matrix in each logic block receives as its inputs
all signals from the global bus. Under software control, up to 40 of these signals can be
selected as inputs to the logic block.
Each macrocell also generates a foldback product term. This signal goes to the regional
bus and is available to 16 macrocells. The foldback is an inverse polarity of one of the
macrocell’s product terms. The 16 foldback terms in each region allow generation of
high fan-in sum terms (up to 21 product terms) with little additional delay.
Open-collector Output Option This option enables the device output to provide control signals such as an interrupt that
can be asserted by any of the several devices.

ATF1508ASV(L)
Programmable Pin-
keeper Option for
Inputs and I/Os
The ATF1508ASV(L) offers the option of programming all input and I/O pins so that “pin-
keeper” circuits can be utilized. When any pin is driven high or low and then subse-
quently left floating, it will stay at that previous high- or low-level. This circuitry prevents
unused input and I/O lines from floating to intermediate voltage levels, which causes
unnecessary power consumption and system noise. The keeper circuits eliminate the
need for external pull-up resistors and eliminate their DC power consumption.
Input Diagram
Speed/Power
Management
The ATF1508ASV(L) has several built-in speed and power management features. The
ATF1508ASV(L) contains circuitry that automatically puts the device into a low-power
standby mode when no logic transitions are occurring. This not only reduces power con-
sumption during inactive periods, but also provides proportional power-savings for most
applications running at system speeds below 5 MHz.
To further reduce power, each ATF1508ASV(L) macrocell has a reduced-power bit fea-
ture. This feature allows individual macrocells to be configured for maximum power-
savings. This feature may be selected as a design option.
I/O Diagram

1408H–PLD–7/05
All ATF1508 also have an optional power-down mode. In this mode, current drops to
below 10 mA. When the power-down option is selected, either PD1 or PD2 pins (or
both) can be used to power down the part. The power-down option is selected in the
design source file. When enabled, the device goes into power-down when either PD1 or
PD2 is high. In the power-down mode, all internal logic signals are latched and held, as
are any enabled outputs.
All pin transitions are ignored until the PD pin is brought low. When the power-down fea-
ture is enabled, the PD1 or PD2 pin cannot be used as a logic input or output. However,
the pin’s macrocell may still be used to generate buried foldback and cascade logic
signals.
All power-down AC characteristic parameters are computed from external input or I/O
pins, with reduced-power bit turned on. For macrocells in reduced-power mode
(reduced-power bit turned on), the reduced-power adder, tRPA, must be added to the AC
parameters, which include the data paths tLAD, tLAC, tIC, tACL, tACH and tSEXP
.
Each output also has individual slew rate control. This may be used to reduce system
noise by slowing down outputs that do not need to operate at maximum speed. Outputs
default to slow switching, and may be specified as fast switching in the design file.
Design Software
Support
ATF1508ASV(L) designs are supported by several third-party tools. Automated fitters
allow logic synthesis using a variety of high-level description languages and formats.
Power-up Reset
The ATF1508ASV is designed with a power-up reset, a feature critical for state machine
initialization. At a point delayed slightly from VCC crossing VRST, all registers will be ini-
tialized, and the state of each output will depend on the polarity of its buffer. However,
due to the asynchronous nature of reset and uncertainty of how VCC actually rises in the
system, the following conditions are required:
1. The VCC rise must be monotonic,
2. After reset occurs, all input and feedback setup times must be met before driving
the clock pin high, and,
3. The clock must remain stable during TD.
The ATF1508ASV has two options for the hysteresis about the reset level, VRST, Small
and Large. To ensure a robust operating environment in applications where the device
is operated near 3.0V, Atmel recommends that during the fitting process users configure
the device with the Power-up Reset hysteresis set to Large. For conversions, Atmel
POF2JED users should include the flag “-power_reset” on the command line after “file-
name.POF”. To allow the registers to be properly reinitialized with the Large hysteresis
option selected, the following condition is added:
4. If VCC falls below 2.0V, it must shut off completely before the device is turned on
again.
When the Large hysteresis option is active, ICC is reduced by several hundred micro-
amps as well.
Security Fuse Usage A single fuse is provided to prevent unauthorized copying of the ATF1508ASV(L) fuse
patterns. Once programmed, fuse verify is inhibited. However, User Signature and
device ID remains accessible.

ATF1508ASV(L)
Programming
ATF1508ASV(L) devices are in-system programmable (ISP) devices utilizing the 4-pin
JTAG protocol. This capability eliminates package handling normally required for pro-
gramming and facilitates rapid design iterations and field changes.
Atmel provides ISP hardware and software to allow programming of the
ATF1508ASV(L) via the PC. ISP is performed by using either a download cable, a com-
parable board tester or a simple microprocessor interface.
To allow ISP programming support by the Automated Test Equipment (ATE) vendors,
Serial Vector Format (SVF) files can be created by the Atmel ISP software. Conversion
to other ATE tester format beside SVF is also possible
ATF1508ASV(L) devices can also be programmed using standard third-party program-
mers. With third-party programmer, the JTAG ISP port can be disabled thereby allowing
four additional I/O pins to be used for logic.
Contact your local Atmel representatives or Atmel PLD applications for details.
ISP Programming
Protection
The ATF1508ASV(L) has a special feature that locks the device and prevents the inputs
and I/O from driving if the programming process is interrupted for any reason. The
inputs and I/O default to high-Z state during such a condition. In addition the pin-keeper
option preserves the former state during device programming.
All ATF1508ASV(L) devices are initially shipped in the erased state thereby making
them ready to use for ISP.

CPLDs” application note.

Power-down Mode
The ATF1508ASV(L) includes two pins for optional pin-controlled power-down feature.
When this mode is enabled, the PD pin acts as the power-down pin. When the PD1 and
PD2 pin is high, the device supply current is reduced to less than 5 mA. During power-
down, all output data and internal logic states are latched and held. Therefore, all regis-
tered and combinatorial output data remain valid. Any outputs that were in a high-Z state
at the onset will remain at high-Z. During power-down, all input signals except the
power-down pin are blocked. Input and I/O hold latches remain active to ensure that
pins do not float to indeterminate levels, further reducing system power. The power-
down pin feature is enabled in the logic design file. Designs using either power-down pin
may not use the PD pin logic array input. However, buried logic resources in this macro-
cell may still be used.

ATF1508ASV(L)
1408H–PLD–7/05
ATF1508ASV(L)
JTAG-BST Overview
The JTAG-BST (JTAG boundary-scan testing) is controlled by the Test Access Port
(TAP) controller in the ATF1508ASV(L). The boundary-scan technique involves the
inclusion of a shift-register stage (contained in a boundary-scan cell) adjacent to each
component so that signals at component boundaries can be controlled and observed
using scan testing principles. Each input pin and I/O pin has its own Boundary-scan Cell
(BSC) in order to support boundary-scan testing. The ATF1508ASV(L) does not cur-
rently include a Test Reset (TRST) input pin because the TAP controller is automatically
reset at power-up. The six JTAG-BST modes supported include: SAMPLE/PRELOAD,
EXTEST, BYPASS and IDCODE. BST on the ATF1508ASV(L) is implemented using
the Boundary-scan Definition Language (BSDL) described in the JTAG specification
(IEEE Standard 1149.1). Any third-party tool that supports the BSDL format can be used
to perform BST on the ATF1508ASV(L).
The ATF1508ASV(L) also has the option of using four JTAG-standard I/O pins for in-
system programming (ISP). The ATF1508ASV(L) is programmable through the four
JTAG pins using programming-compatible with the IEEE JTAG Standard 1149.1. Pro-
gramming is performed by using 5V TTL-level programming signals from the JTAG ISP
interface. The JTAG feature is a programmable option. If JTAG (BST or ISP) is not
needed, then the four JTAG control pins are available as I/O pins.
JTAG Boundary-scan The ATF1508ASV(L) contains up to 96 I/O pins and four input pins, depending on the
device type and package type selected. Each input pin and I/O pin has its own bound-
Cell (BSC) Testing
ary-scan cell (BSC) in order to support boundary-scan testing as described in detail by
IEEE Standard 1149.1. A typical BSC consists of three capture registers or scan regis-
ters and up to two update registers. There are two types of BSCs, one for input or I/O
pin, and one for the macrocells. The BSCs in the device are chained together through
the (BST) capture registers. Input to the capture register chain is fed in from the TDI pin
while the output is directed to the TDO pin. Capture registers are used to capture active
device data signals, to shift data in and out of the device and to load data into the update
registers. Control signals are generated internally by the JTAG TAP controller. The BSC
configuration for the input and I/O pins and macrocells are shown below.
BSC Configuration Pins and Macrocells (Except JTAG TAP Pins)
Note:
The ATF1508ASV(L) has pull-up option on TMS and TDI pins. This feature is selected as a design option.

Using “C” Product for Industrial
There is very little risk in using “C” devices for industrial applications because the VCC conditions for 3.3V products are
the same for commercial and industrial (there is only 15°C difference at the high end of the temperature range). To use
commercial product for industrial temperature ranges, de-rate ICC by 15%.
