Description
The Atmel V5000 is an easy to use, high density programmable logic device. Its simple, regu-
lar architecture translates into increased utilization and high performance.
The ATV5000 has one programmable combinatorial logic array. This guarantees easy inter-
connection of and uniform performance from all nodes. "Sum terms", which are easy to use
groupings of AND-OR gates, provide combinatorial logic blocks. Sum terms can be wire-
OR’d together to integrate larger logic blocks. To expand the levels of logic, buried sum terms
feed back into the logic array. The 52 I/O pins can each be driven by a register or a sum term.
Each I/O pin has an individually enabled input latch.
All 128 registers are configurable as D- or T-types without using extra logic gates. Individual
sum terms, asynchronous presets, resets and clocks give each flip-flop added flexibility. A
direct "clock from pin" option guarantees synchronization and fast clock to output perform-
ance.
Standard, off-the-shelf third-party software tools and programmers support the ATV5000.
This minimizes start-up investment and improves product support.

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.

Quadrant Logic Diagram
and Description
The ATV5000 has: four identical quadrants, 52 identical input/
output logic cells, and 24 identical buried logic cells. The uni-
versal bus routes true and false signals from each of the 52 I/O
pins to all four quadrants. Regional buses route each quadrant’s
flip-flop Q and Q locally. The eight input-only pins are available
in every regional bus.
Each logic cell has a number of "regional" and "universal" prod-
uct terms (see Figure 3). The I/O logic cells (Figures 7, 8, 9)
contain three sum terms, two flip-flops, and an I/O buffer. Sum
term B has five product terms - two universal and three regional.
Sum terms A and C each have four product terms - one universal
and three regional. Flip-flop Q1 has global asynchronous preset,
reset, and clock product terms. Flip-flop Q2 has universal asyn-
chronous reset and clock terms and a regional asynchronous pre-
set term. There is one universal product term for the I/O pin out-
put enable.
The buried logic cells (Figure 4) each contain one flip-flop. The
sum term has one universal product term and four regional prod-
uct terms for a total of five. The flip-flop has universal asynchro-
nous preset, reset, and clock terms. In addition, in each buried
logic cell the sum term can be fed back into the regional bus
instead of the flip-flop. This allows for logic expansion.
Regional product terms have as inputs all quadrant flip-flop out-
puts (or buried flip-flop inputs) and the eight dedicated input
pins. Universal product terms have the same inputs plus the 52
I/O pins and their complements.

to the I/O cell.
The ATV5000 retains the ATV2500’s ability to bury both reg-
isters in the I/O cell and still output a combinatorial signal (see
Figure 8). A new feature, unique to the ATV5000, is the ability
to output Q1 and feedback the combinatorial term directly (see
Figure 7). This high speed logic expansion term increases the
devices flexibility and gate utilization.

Buried Logic Cells
Each quadrant has six buried logic cells (see Figure 4). Each cell
contains one sum term with five product terms, a flip-flop, and
individual preset, clear, and clock terms. A configuration bit se-
lects either the Q output or the D input for feedback into the
regional bus.

Flip-Flop Clock Options
Each register may be connected to its regional clock to provide
fast clock-to-output timing (see Figure 5). In this "synchronous"
mode, the clock is one of four input pins, a unique clock pin for
each chip quadrant. One product term defines each flip-flop’s
clock in the "asynchronous" mode.
In the "synchronous" mode, the regional clock is ANDed with
the product term. This provides the fast timing of a synchronous
clock with the local control of the product term.

I/O Pin Latches
Each I/O pin of the ATV5000 has an input latch which can be
individually enabled or disabled (see Figure 6). Each chip quad-
rant has a unique latch clock. When the latch is inactive, pin
input flows directly into the array. When activated, the latch is
flow-through when the clock signal is low, and data is captured
on the clock’s rising edge.

Flip-Flop Types
Each flip-flop in the ATV5000 may be configured as either a T-
or D-type flip-flop. A T-type flip-flop can also easily be config-
ured into a JK or SR flip-flop.
