GENERAL DESCRIPTION
The PALCE16V8 is an advanced PAL® device built with
low-power, high-speed, electrically-erasable CMOS
technology. It is functionally compatible with all 20-pin
GAL devices. The macrocells provide a universal device
architecture. ThePALCE16V8 will directly replace the
PAL16R8 and PAL1OH8 series devices, with the excep-
tion of the PAL16C1.
Device logic is automatically configured according to the
user's design specification. Design is simplified by
PALASM design software, allowing automatic creation
of a programming file based on Boolean or state equa-
tions. PALASM software also verifies the design and
can provide test vectors for the finished device. Pro-
gramming can be accomplished on standard PAL
device programmers.

functional yields and high reliability
The PALCE16V8 utilizes the familiar sum-of-products
(AND/OR) architecture that allows users to implement
complex logic functions easily and efficiently. Multiple
levels of combinatorial logic can always be reduced to
sum-of-products form, taking advantage of the very
wide input gates available in PAL devices. The equa-
tions are programmed into the device through floating-
gate cells in the AND logic array that can be erased elec-
trically.
The fixed OR array allows up to eight data product terms
per output for logic functions. The su m of these products
feeds the output macrocell. Each macrocell can be pro-
grammed as registered or combinatorial with an active-
HIGH or active-LOW output. The output configuration is
determined by two global bits and one local bit control-
ling four multiplexers in each macrocell.
