Functional Logic Diagram Description

There are 52 identical input/ouput logic cells and 24 identical

buried logic cells in the ATV5000. Each I/O cell has two flip-

flops, up to three sum terms, individual clock, reset, and preset

terms per flip-flop, and one output enable term. Independent of

output configuration, all flip-flops are always usable, and have

at least four product term inputs each.

Each I/O pin (52 total) signal or its latched version drives the

logic array. There is one latch clock per quadrant.

The ATV5000 has four identical quadrants (see Figure 2). The

universal bus routes true and false signals from each of the 52

I/O pins to all four quadrants. Regional buses route each quad-

rant’s flip-flop Q and Q locally. The eight input-only pins are

available in all four regional buses.

Each logic cell has a number of "regional" and "universal" prod-

uct terms (see Figure 1). The I/O logic cells contain three sum

terms, two flip-flops, and an I/O buffer.

The buried logic cells each contain one flip-flop. In addition, in

each buried logic cell the sum term can drive the regional bus.

This allows for logic expansion.

Serial register preload and observability simplify testing. All

registers automatically clear at power up.

*NOTICE: Stresses beyond those listed under "Absolute Maximum

Ratings" may cause permanent damage to the device. This is a

stress rating only and functional operation of the device at these

or any other conditions beyond those indicated in the operational

sections of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect de-

vice reliability.

Note:

1. Minimum voltage is -0.6 V dc which may undershoot to -2.0 V

for pulses of less than 20 ns. Maximum output pin voltage is

than 20 ns.
