DescriptionThe ATF1502ASV is a high-performance, high-density complex programmable logic
device (CPLD) that utilizes A tmel’s proven electrically-erasable technology. With 32
logic macrocells and up to 36 inputs, it easily integrates logic from several TTL, SSI,
MSI, LSI and classic PLDs. The ATF1502ASV’s e nhanced routing switch matrices
increase usable gate count and the odds of successful pin-locked design modificat ions.
The ATF1502ASV has up to 32 bi-directional I/O pins and four dedicated input pins,
depending o n the t ype of d evice pac kage se lected . Eac h dedica ted pi n can also se rve
as a global co ntrol signa l, registe r clock, regi ster reset or output enable . Each of the se
control signals can be selected for use individually within each macrocell.

Each of the 32 macrocells generates a buried feedback that goes to t he 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 f rom the glob al bus. Each m acroc ell also generates a foldb ack logic term that goes to a regional bus . Cascade log ic between
macrocells in the ATF1502ASV allows fast, efficient generation of complex logic functions. The ATF1502ASV contains four such logic chains, each capable of creating sum
term logic with a fan-in of up to 40 product terms.
The ATF1502ASV macroc ell, 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.
1615H–PLD–2/04
Unused product t erms are automatically disabled by the compiler to decrease power
consum ption. A se curity fus e, when pro grammed , protects the conten ts of the
ATF1502ASV. 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 Signat ure
is accessible regardless of the state of the security fuse.
The ATF1502ASV device is an in-system programmab le ( ISP) device. It uses the industry standard 4-pin JTAG interface (IEEE Std. 1149.1), and is fully compliant with JTAG’s

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.

ATF1502ASV
Each ATF1502ASV 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 term s 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.
The ATF15 02ASV’s lo gic structur e is design ed to effici ently suppo rt 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 combin atorial outputs, the fixed le vel
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.
1615H–PLD–2/04
ATF1502ASV
Flip-flopThe ATF1502A SV’s flip-flop h as very flexibl e data and control func tions. The dat a input
can com e fro m eit her the X OR gate , from a sepa ra te produ ct t erm o r directl y from the
I/O pin. Selecting the separat e product term allows creation of a buried registered feedback within a combinatorial output macrocell. (This feature is automatically implemented
by the fitter software). In a ddition to D, T, JK and SR operation, the flip-flop can also be
configured as a flow-through latch. In this m ode, da ta p asse s throug h when the clock is
high and is latched when the clock is low.
The clock itself can be either one of the Global CLK signals (GCK[0 : 2]) or an individual
product term. The flip-flop changes state on t he 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 signa l (product term) is
low, all clock edges a re igno red. T he flip-fl op’s asy nchrono us re set sign al (AR ) can be
either the Global Clear (GCLEAR), a product term, or always off. AR can also be a l ogic
OR of G CLE AR with a p rodu ct ter m. The asy nchro no us pre se t (AP) can be a pr oduc t
term or always off.
Extra FeedbackThe ATF1502ASV mac rocell output can be selected as registered or combinatorial.The
extra burie d fee dback signa l can be eith er com binato rial or a regist ered s ign al rega rdless of whether the output is combinatorial or registered. (This enhancement function is
automatically implemented by the fitter software.) Feedback of a buried combinatorial
output allows the creation of a second latch within a macrocell.
I/O ControlThe 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 subs et of the I /O macr ocell s. This se lection is
automatically done by the fitter software when the I/O is configured as an input, all macrocell resources are still available, including the buried feedback, expander and cascade
logic.
Global Bus/Switch Matrix The global bus cont ains all input and I/O p in sign als as wel l as t he buried feedback sig-
nal from all 32 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.
Foldback BusEach macrocell also generates a foldback product term. This signal goes to the regional
bus and is availa ble to four m ac roc ells. T he foldback is an inverse pola rity of on e of the
macrocell’s product terms. The four foldback terms in each region allow generation of
high fan-in sum terms (up to nine product terms) with little additional delay.
Prog rammable Pinkeeper Option for
Inputs and I/Os
The ATF1502ASV offers the option of programming all input and I/O pins so that pinkeeper circuits can be utilized. When any pin is driven high or low and then subsequently left float ing, it will stay at t hat previous high or low le vel. This circui try prev ents
unused input and I/O lines from floating to intermediate voltage levels, whic h causes
unnecessary power consumption and system noise. The keeper c ircuits eliminate the
need for external pull-up resistors and eliminate their DC power consumption.

PROGRAMMABLE
OPTION
The ATF1502ASV has several built-in speed and power managem ent features.
To further reduce power, each ATF1502ASV macrocell has a reduced-power bit feature.
To reduce power consumption this feature may be actived (by changing the default
value of OFF to ON) for any or all macrocells.
The ATF1502ASV also has an optional power-down mode. In this mode, current drops
to belo w 15 m A. Wh en t he pow er- down o pti on is se lect ed, e ither PD 1 o r 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 feature is enabled, the PD1 or PD2 pin cannot be used as a logic input or output. However,
the pin’s macrocell m ay still be used to generate buried foldback and cascade logic
signals.

Support
ATF1502ASV 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 ResetThe ATF1502ASV is designed with a power-up reset, a feature critical for state machine
initi aliz atio n. At a p oin t d ela yed sli gh tly fr om V

due to the asynchronous nature of reset and uncertainty of how V

1. The V

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 T
The ATF1502ASV has two options for th e hysteresis about the reset level, V
and Large. To ensure a robus t operat ing enviro nment in applicatio ns whe re the devic e
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 th e command line after “filename.POF”. To allow the reg isters to be properly rei nitialized with the La rge hysteresis
option selected, the following condition is added:

ProgrammingATF1502ASV devices are in-system programmable (ISP) devices utilizing the 4-pin
JTAG protocol. This capability eliminates package handling normally required for programming and facilitates rapid design iterations and field changes.

Overview
The ATF1502AS V has a sp ecial feature th at locks the device and prevents the inputs
and I/O from drivin g if the programmi ng process is inte rrupted for any reas on. The
inputs and I/O default to high-Z state during such a condition. In addition, the pin-keeper
option preserves the previous state of the input and I/O PMS during programming.
All ATF1502ASV devices are ini tially shipped in the erased state, thereby making them
ready to u se for ISP.
Note:For more infor mation refer to the “Designing for In-System Programmability with At mel
CPLDs” application note.
The JTAG boundary-scan testing is controlled by the Test Access Port (TAP) controller
in the ATF1502 ASV. The boundary-scan technique involves t he inclusio n 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
methods. Each input pin and I/O pin has its own boundary-scan cell (BSC) to support
boundary-scan testing. The ATF1502ASV does not include a Test Reset (TRST) input
pin because the TAP controller is automatically reset at power-up. The five JTAG modes
supported include: SAMPLE/PRELOAD, EXTEST, BYPASS, IDCODE and HIGHZ. The
ATF1502ASV’s ISP can be fully described using JTAG’s BSDL as described in IEEE
Standard 1149.1b. This allow s ATF1502ASV programming to be described and implemented using any one of the third-party development tools supporting this standard.
The ATF1502ASV has the option of using four JTAG-standard I/O pins for boundaryscan testing (BST) and in-system programming (ISP) purposes. The ATF1502AS V is
programmable through the four JTAG pins using the IEEE standard JTAG programming
protocol established by IEEE S tan dard 1149.1 us ing 5V TTL -level program m ing sig nals
from the ISP interface for in-system programming. The JTAG feature is a programmable
option . If JTA G (B ST or ISP ) is not nee ded , the n the f our J TAG c ontr ol pi ns a re av ailable as I/O pins.

ATF1502ASV
The ATF1502ASV contains up to 32 I/O pins and four input pins, depending on the
device typ e and pack age ty pe sele cted. Each inpu t pin a nd I/O pi n has its own bou ndary-scan cell (BSC) i n order to sup port bou ndary-scan testing as desc ribed i n detail by
IEEE Standard 1149.1. A typical BSC consi sts of three captur e registers or scan registers and up to two update registers. There are two types of BSCs, one for input or I/O
pin, and one for t he m acr ocell s. The B SC s in the d evi ce ar e chai ned t ogethe r thro ug h
the capture registers. Input to the capture register chain is fed in from the TDI pin while
the output is d irected to the TDO pin. Capture registers are used to capture a ctive
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 is shown below.

Power-down ModeThe ATF1502ASV includes an optional pin-controlled power-down feature. When this
mode is enabled, the PD pin acts as the power-down pin. Wh en the PD pin is high, the
device supply current is reduc ed to less than 3 mA. Du ring power-down, all output data
and internal logic st ates are latche d and held. Th erefore, all registered and c ombinat orial o u tput da ta r em ain val id. An y ou tput s t ha t w er e i n a hig h -Z s tat e at the on se t w ill

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 des ign file. Designs using the power-down pin m ay not us e th e P D pi n l ogic

the buried feedback and foldback product term array inputs.
