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. The PALCE16V8 will directly replace the PAL16R8 and PAL10H8 series devices, with the exception of the PAL16C1.

DISTINCTIVE CHARACTERISTICS

■ Pin and function compatible with all 20-pin GAL devices

■ Electrically erasable CMOS technology

provides reconfigurable logic and full testability

■ High-speed CMOS technology

— 5-ns propagation delay for “-5” version

— 7.5-ns propagation delay for “-7” version

■ Direct plug-in replacement for the PAL16R8

series and most of the PAL10H8 series

■ Outputs programmable as registered or

combinatorial in any combination

■ Peripheral Component Interconnect (PCI) compliant

■ Programmable output polarity

■ Programmable enable/disable control

■ Preloadable output registers for testability

■ Automatic register reset on power up

■ Cost-effective 20-pin plastic DIP, PLCC, and SOIC packages

■ Extensive third-party software and programmer

support through FusionPLD partners

■ Fully tested for 100 programming and

functional yields and high reliability

■ 5 ns version utilizes a split leadframe for

improved performance
