Functional Description
The Cypress PALCE22V10 is a CMOS Flash-erasable
second-generation programmable array logic device. It is
implemented with the familiar sum-of-products (AND-OR)
logic structure and the programmable macrocell.
The PALCE22V10 is executed in a 24-pin 300-mil molded DIP,
a 300-mil cerDIP, a 28-lead square ceramic leadless chip
carrier, a 28-lead square plastic leaded chip carrier, and
provides up to 22 inputs and 10 outputs. The PALCE22V10
can be electrically erased and reprogrammed. The program-
mable macrocell provides the capability of defining the archi-
tecture of each output individually. Each of the ten potential
outputs may be specified as "registered" or "combinatorial."
Polarity of each output may also be individually selected,
allowing complete flexibility of output configuration. Further
configurability is provided through "array" configurable "output
enable" for each potential output. This feature allows the 10
outputs to be reconfigured as inputs on an individual basis, or
alternately used as a combination I/O controlled by the
programmable array.
PALCE22V10 features a variable product term architecture.
There are 5 pairs of product term sums beginning at 8 product
terms per output and incrementing by 2 to 16 product terms
per output. By providing this variable structure, the
PALCE22V10 is optimized to the configurations found in a
majority of applications without creating devices that burden
the product term structures with unusable product terms and
lower performance.
Additional features of the Cypress PALCE22V10 include a
synchronous preset and an asynchronous reset product term.
These product terms are common to all macrocells, elimi-
nating the need to dedicate standard product terms for initial-
ization functions. The device automatically resets upon
power-up.
The PALCE22V10, featuring programmable macrocells and
variable product terms, provides a device with the flexibility to
implement logic functions in the 500- to 800-gate-array
complexity. Since each of the ten output pins may be individ-
ually configured as inputs on a temporary or permanent basis,
functions requiring up to 21 inputs and only a single output and
down to twelve inputs and ten outputs are possible. The ten
potential outputs are enabled using product terms. Any output
pin may be permanently selected as an output or arbitrarily
enabled as an output and an input through the selective use
of individual product terms associated with each output. Each
of these outputs is achieved through an individual program-
mable macrocell. These macrocells are programmable to
provide a combinatorial or registered inverting or non-inverting
output. In a registered mode of operation, the output of the
register is fed back into the array, providing current status
information to the array. This information is available for estab-
lishing the next result in applications such as control state
machines. In a combinatorial configuration, the combinatorial
output or, if the output is disabled, the signal present on the I/O
pin is made available to the array. The flexibility provided by
both programmable product term control of the outputs and
variable product terms allows a significant gain in functional
density through the use of programmable logic.
Along with this increase in functional density, the Cypress
PALCE22V10 provides lower-power operation through the use
of CMOS technology, and increased testability with Flash
reprogrammability.
