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 congured according to the user’s design specication. A design is
implemented using any of a number of popular design software packages, allowing automatic
creation of a programming le based on Boolean or state equations. Design software also veries
the design and can provide test vectors for the nished 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 efciently. 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 oating-gate
cells in the AND logic array that can be erased electrically.
