FUNCTIONAL DESCRIPTION
The 10H20EV8/10020EV8 is an ultra
high-speed universal ECL PAL-type device.
Combining versatile Output Macrocells with a
standard AND/OR single programmable
array, this device is ideal in implementing a
user’s custom logic.
As can be seen in the Logic Diagram, the
device is a two-level logic element with a
programmable AND array. The 20EV8 can
have up to 20 inputs and 8 outputs. Each
output has a versatile Macrocell whereby the
output can either be configured as a
dedicated input, a dedicated combinatorial
output with polarity control, a bidirectional I/O,
or as a registered output that has both output
polarity control and feedback into the AND
array.
The device also features 90 product terms.
Two of the product terms can be used for a
global asynchronous preset and/or reset.
Eight of the product terms can be used for
individual output enable control of each
Macrocell. The other 80 product terms are
distributed among the outputs. Four of the
outputs have eight product terms, while the
other four have 12. This arrangement allows
the utmost in flexibility when implementing
user patterns.
Output Logic Macrocell
The 10H20EV8/10020EV8 incorporates an
extremely versatile Output Logic Macrocell
that allows the user complete flexibility when
configuring outputs.
As seen in Figure 1, the 10H20EV8/
10020EV8 Output Logic Macrocell consists of
an edge-triggered D-type flip-flop, an output
select MUX, and a feedback select MUX.
Fuses S0 and S1 allow the user to select
between the various cells. S1 controls
whether the output will be either registered
with internal feedback or combinatorial I/O.
S0 controls the polarity of the output (Active-
HIGH or Active-LOW). This allows the user to
achieve the following configurations:
Registered Active-HIGH output, Registered
Active-LOW output, Combinatorial Active-
HIGH output, and Combinatorial Active-LOW
output. With the output enable product term,
this list can be extended by adding the
configurations of a Combinatorial I/O with
Polarity or another input.
