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

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.
