GENERAL DESCRIPTION

The PALCE20V8 is an advanced PAL device built with low-power, high-speed, electrically-

erasable CMOS technology. Its macrocells provide a universal device architecture. The

PALCE20V8 is fully compatible with the GAL20V8 and can directly replace PAL20R8 series

devices and most 24-pin combinatorial PAL devices.

Device logic is automatically conﬁgured according to the user’s design speciﬁcation. A design is

implemented using any of a number of popular design software packages, allowing automatic

creation of a programming ﬁle based on Boolean or state equations. Design software also veriﬁes

the design and can provide test vectors for the ﬁnished device. Programming can be

accomplished on standard PAL device programmers.

The PALCE20V8 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 equations are programmed into the device through ﬂoating-gate

cells in the AND logic array that can be erased electrically.
