Description
The ATV2500H/L is the most powerful programmable logic device available in a 40­pin package. Increased product terms, sum terms, and flip-flops translate into many more usable gates. High gate utilization is easily obtainable.
The ATV2500H/L is organized around a global bus. All pin and feedback terms are always available to every logic cell. Each of the 38 logic pins and their complements are array inputs, as well as the true and false outputs of each of the 48 flip-flops.

There are 416 product terms availab le. Four product terms are input to each sum term. The three sum terms per logic cell can be combined to provide up to twelve product terms, combinatorial and registered. Independent of output config­uration, the two flip-flops are always usable, and always have at least four product term inputs.
Product terms are av ailable providing async hronous resets, flip-flop clocks, and output enables. One reset and one clock term are provi ded per flip-f lop, with one ena ble term per output. Eight p ro duc t t erms pr ovide local synchro­nous presets, divided up in to bank s of f our and eight f lip­flops. Registe r preload an d buried regis ter observ ability simplify testi ng. The de vice has an inte rnal po wer up cle ar function.

Functional Logic Diagram Description
The ATV2500H/L Functional Logic Diagram describes the interconnections between the input, feedback p ins and logic cells. All interconnections are routed through the glo­bal bus.
The ATV250 0H/L is a st raight forward and uniform PLD. The twenty-four macr ocells are numbered 0 th rough 23. Each macrocell conta ins 17 AND gates. A ll AND gates have 172 inputs. The five lower product terms provide AR1, CK1, CK2, AR2, and OE. These ar e: one asynchronous reset and clock per fli p-flop, a nd an output ena ble. The top
twelve product te rms are group ed into th ree sum ter ms, which are used as shown in the macrocell diagrams.
Eight synchronous preset terms are distributed in a 2/4 pat­tern. The first four macrocells share Preset 0, the next two share Preset 1, a nd so on, end ing w ith th e last two ma cro­cells sharing Preset 7.
The fourteen dedicated inputs and their complements use the numbered positions in the global bus as shown. Each macrocell provides six inputs to the global bus: (left to right) flip-flop Q2 true an d false, flip-flop Q1 true a nd false, and the pin true and false. The positions occupied by these sig­nals in the global bus are the six numbers in the bus dia­gram next to each macrocell.

Preload and Observability of Registered Outputs
The ATV2500H/L's re gisters are provid ed with cir cuitry t o allow loading of eac h regi ster async hro nously with eit her a high or a low. This feature will simp lify testing since any state can be forced into the registers to control test sequencing. A V
IH
level on the O dd I/O pin s will force th e
appropriate register high; a V
IL
will force it low, independent
of the polarity or other configuration bit settings. The preload sta te i s enter ed by p lacin g an 11V to 1 4V sig-
nal on pin 38 on the DIP and pin 42 on the SMP . Wh en th e
clock term is puls ed hi gh, ( pin 2 1 o n the DIP , p in 23 on th e SMP) the data on the I/O pins is placed into the 12 regis­ters chosen by the Q select and even/odd select pins.
Register 2 observabili ty mo de is ente re d by placin g an 11V to 14V signal on pin 2 (DIP or S MP ). In thi s m ode, the c on­tents of the buried register bank will appear on the associ­ated outputs when the OE control signals are active.
P ower-Up Reset
The registers in the ATV2500H/L are designed to reset dur­ing power-up. At a point de la yed sli ghtly fro m V
CC
crossing
3.8V, all registers will be reset to the low state. The output state will depend on the polarity of the output buffer.
This feature is critical for state machine initialization. How­ever, due to the asynchronous nature of reset and the uncertainty of h ow V
CC
actually rises in the sys tem, the fo l-
lowing conditions are required:
1. The V
CC
rise must be monotonic,
2. After reset occurs, all input and feedback setup times must be met before driving the clock term high,
3. The signals from which the clock is derived must remain stable during t
PR
.

Security Fuse Usage
A single fuse is provided to pre vent unauthorized copying of the ATV2500H/L fuse patterns. Once programmed, the outputs will read programmed during verify. The security fuse should be programmed last, as its effect is immediate.
The security fuse also inhibits preload and Q2 observabil­ity.
Atmel CMOS PLDs
Atmel's Erasable Programmable Logic Devices utilize an advanced 1.25-micron CMOS EPROM technology. This technology's state of the art features are the optimu m com­bination for PLDs:
• CMOS techno logy provides high speed, low power, and
high noise immunity.
• EPROM technology is the most cost effective method for
producing PLDs - surpassing bipolar fusible link technology in low cost, while providing the necessary reprogrammability.
• EPROM reprogrammability, which is 100% tested before
shipment, provides inherently better programmability and reliability than one-time fusible PLDs.
• Atmel's EPROM process has proven extremely reliable
in the volume production of a full line of advanced EPROM memory products, from 64K to one-megabit devices.
Using the ATV2500H/L's Many Advanced Features
The ATV2500H/L's flexibility puts more usable gates in 40 pins than other PLDs. Some of the ATV2 500H/L 's key fe a­tures are:
• Asynchronous Clocks -
Each of the flip-flo ps in the AT V2500H/L has a dedicate d product term driving the clock. The user is no longer con­strained to using one clock for all the registers. Buried state machines, counters, and registers can all c oexist in one device, while running on separate clocks. The ATV2500H/L clock period matches that of similar synchronous devices.
• A Total of 48 Registers -
The ATV2500H/L pro vides two flip -flops for each ou tput macrocell - a total of 48. Each register has its own clock and reset product terms, as well as its own sum term.
• Independent I/O Pin and Feedback Paths ­Each I/O pin on the ATV2500/H has a dedicated input path.
Each of the 48 regi sters has in divi dual fe edbac k ter ms into the array. This feature, combined with individual product terms for each I/O's output enable, facilitates designs using bi-directional I/O buses.
• Three Sum T erms per Macrocell ­The ATV2500H/L macrocell can be configured with one
SUM term feeding the output, and still have two SUM terms feeding the flip-flops. This is the simplest method for inter­facing with an I/O bus, and no flip-flops need be sacrificed.
• Combinable Sum Terms ­Each output macrocell's three SUM terms can be combined
in an OR gate before the output or the register. This pro­vides up to twelve product terms per output or flip-flop. When the registered output configuration is chosen, eight terms are automatically available to D1. The four terms feeding D2 can also be shared with D1, giving i t a total of twelve. In the combinatorial mode, four, eight, or twelve terms can feed the output, with the middle four still driving D1 and the bottom four still driving D2.
Programming Software Support
Software which is c apable of transform ing Boolean equa­tions, state machine descriptions and truth tables into JEDEC files for the ATV2500H/L is currently available from several PLD software vendors. Please refer to the
Pro-
grammable Logic Development Tools
section for a com-
plete listing of the PLD software support.
Erasure Characteristics
The entire memory array of an ATV2500H/L is erased after exposure to ultraviolet light at a wavel ength of 2537 Å. Complete erasure is assured afte r a minimum of tw enty minutes exposure using 12,000 µW/cm
2
intensity lam ps spaced one inch away from the chip. Minimum erase time for lamps at other intensity ratings can be calc ulated from the minimum integrat ed erasu re do se of f ifteen W
sec/cm2. To prevent unintentional erasure, an opaque label is rec­ommended to cover the clear window on any UV erasable PLD which will be subjected to continuous fluorescent indoor lighting or sunligh t.
