PALCE20V8H-15PC/4

Programmable Logic Device Pld Overview

The PALCE20V8H-15PC/4 is a high-speed, electrically erasable CMOS programmable logic device manufactured by Lattice Semiconductor. It features a universal macrocell architecture compatible with GAL20V8 and PAL20R8 devices. The '-15' speed grade indicates a maximum propagation delay of 15 ns. The device is housed in a 28-pin PLCC package. Key electrical characteristics include a 5-ns propagation delay for the '-5' version and 7.5-ns for the '-7' version, while this specific part operates at the slower -15 speed grade. It supports individually programmable registered or combinatorial outputs and includes automatic register reset on power-up.

Programmable Logic Device Pld Feature Summary

• Electrically erasable CMOS technology enabling reconfigurable logic
• Pin and function compatible with GAL20V8 and PAL20R8 devices
• 28-pin PLCC package option
• Programmable output polarity and enable/disable control

Programmable Logic Device Pld Applications

• Direct replacement for legacy 24-pin combinatorial PAL devices
• PCI compliant logic interfacing
• General-purpose programmable logic in industrial systems

Programmable Logic Device Pld Procurement Notes

Verify that the specific suffix '/4' corresponds to the intended temperature range or package variant as defined in official Lattice documentation. Confirm compatibility with existing programming hardware, as standard PAL programmers support this device family. Ensure design software generates appropriate programming files based on Boolean or state equations.

Programmable Logic Device Pld Selection Notes

Select this component when a direct pin-compatible upgrade from GAL20V8 or PAL20R8 is required. The -15 speed grade offers lower performance than -5 or -7 variants but may be sufficient for slower timing requirements. Consider the 28-pin PLCC package if board space allows, noting the device also supports 24-pin DIP packages.

Programmable Logic Device Pld Part Context

This device belongs to the PALCE20V8 family, which utilizes low-power, high-speed EEPROM technology. It provides full testability through preloadable output registers and is designed for cost-effective implementation in applications requiring moderate logic density and reprogrammability.

Programmable Logic Device Pld Replacement Considerations

The PALCE20V8H-15PC/4 is designed as a drop-in replacement for GAL20V8 and most 24-pin combinatorial PAL devices. Verify voltage levels and I/O characteristics match the target system before substitution.
