PALCE20V8H-5JC/5

Overview

The PALCE20V8H-5JC/5 is an advanced programmable array logic device manufactured by Lattice Semiconductor. It utilizes low-power, high-speed electrically erasable CMOS technology to provide reconfigurable logic capabilities. The component features a universal macrocell architecture and offers a maximum propagation delay of 5 ns for the -5 speed grade. It is designed as a direct pin-and-function compatible replacement for standard PAL20R8 series devices and other 24-pin combinatorial PALs, supporting both registered and combinatorial output configurations.

Feature Summary

• Electrically erasable CMOS technology enabling full reconfigurability and testability
• High-speed performance with 5 ns propagation delay in the -5 variant
• Universal macrocell architecture allowing individual outputs to be programmed as registered or combinatorial
• Direct plug-in compatibility with PAL20R8 series and most 24-pin combinatorial PAL devices

Applications

• Replacement for legacy 24-pin PAL logic circuits
• PCI compliant logic design implementations
• Systems requiring automatic register reset on power-up

Part Context

This component belongs to the PALCE family, which represents Lattice's evolution from traditional GAL devices to electrically erasable programmable logic. Unlike the GAL20V8C-10LJ mentioned in general market data, the PALCE20V8 series specifically targets users needing non-volatile reprogrammability while maintaining strict pinout compatibility with industry-standard PAL architectures.

Replacement Considerations

The datasheet confirms direct pin and function compatibility with all PAL 20V8 devices. It serves as a drop-in replacement for PAL20R8 series devices. Designers should verify that the target application does not require specific timing characteristics unique to older discrete PAL components.
