Functional Description
The Cypress PALC22V10D is a CMOS Flash Erasable sec-
ond-generation programmable array logic device. It is imple-
mented with the familiar sum-of-products (AND-OR) logic
structure and the programmable macrocell.
The PALC22V10D is executed in a 24-pin 300-mil molded DIP,
a 300-mil cerDIP, a 28-lead square ceramic leadless chip car-
rier, a 28-lead square plastic leaded chip carrier, and provides
up to 22 inputs and 10 outputs. The 22V10D can be electrically
erased and reprogrammed. The programmable macrocell pro-

vides the capability of defining the architecture of each output
individually. Each of the 10 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 com-
bination I/O controlled by the programmable array.
PALC22V10D 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 PAL C
22V10D is optimized to the configurations found in a majority
of applications without creating devices that burden the prod-
uct term structures with unusable product terms and lower per-
formance.
Additional features of the Cypress PALC22V10D include a
synchronous preset and an asynchronous reset product term.
These product terms are common to all macrocells, eliminat-
ing the need to dedicate standard product terms for initializa-
tion functions. The device automatically resets upon pow-
er-up.
The PALC22V10D, featuring programmable macrocells and
variable product terms, provides a device with the flexibility to
implement logic functions in the 500- to 800-gate-array com-
plexity. Since each of the 10 output pins may be individually
configured as inputs on a temporary or permanent basis, func-
tions requiring up to 21 inputs and only a single output and
down to 12 inputs and 10 outputs are possible. The 10 poten-
tial outputs are enabled using product terms. Any output pin
may be permanently selected as an output or arbitrarily en-
abled 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 programmable
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 establishing the next
result in applications such as control state machines. In a com-
binatorial configuration, the combinatorial output or, if the out-
put is disabled, the signal present on the I/O pin is made avail-
able 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
PALC22V10D provides lower-power operation through the
use of CMOS technology, and increased testability with Flash
reprogrammability.

... This parameter is calculated from the clock period at f 16. The registers in the PALC22V10D have been designed with the capability to reset during system power-up. Following power-up, all registers will be reset to a logic LOW state. The output state will depend on the polarity of the output buffer. This feature is useful in establishing state machine initialization. To insure proper operation, the rise in V must be monotonic and the timing constraints depicted in Power-Up Reset Waveform must be satisfied ...
