PALCE20V8H-10JC/4

Programmable Logic Device Pld Overview

The PALCE20V8H-10JC/4 is an electrically erasable programmable logic device (EE PLD) manufactured by Lattice Semiconductor. It utilizes low-power, high-speed CMOS technology and features a universal macrocell architecture. The component offers a maximum propagation delay of 10 ns and operates within a commercial temperature range of 0°C to +70°C. It is housed in a 28-pin Plastic Quad Flat Package (PLCC). The device provides 14 dedicated inputs and 8 I/O lines, with outputs individually programmable as registered or combinatorial. It serves as a direct replacement for standard GAL20V8 devices.

Programmable Logic Device Pld Feature Summary

• Electrically erasable CMOS technology enabling reconfigurable logic
• Pin and function compatible with PAL 20V8 devices
• Outputs individually programmable as registered or combinatorial
• Automatic register reset on power-up

Programmable Logic Device Pld Applications

• Direct plug-in replacement for 24-pin PAL devices

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix /4 against official documentation to confirm the commercial temperature grade (0°C to +70°C) and package variant. Confirm availability status as legacy components may have limited supply chains. Ensure programming equipment supports EE PLD architectures.

Programmable Logic Device Pld Selection Notes

Select this component when a drop-in replacement for GAL20V8 or PAL20R8 is required. The 10 ns speed grade suits moderate-frequency digital logic. Verify that the 28-pin PLCC footprint matches the target PCB layout. Consider the electrical erasability feature if field reprogramming capabilities are necessary compared to one-time programmable alternatives.

Programmable Logic Device Pld Part Context

This part belongs to the PALCE20V8 family, which bridges the gap between traditional PALs and modern CPLDs. It maintains compatibility with older 20V8 pinouts while offering the flexibility of EEPROM-based programming. The H variant typically denotes specific performance or packaging characteristics within the Lattice portfolio.

Programmable Logic Device Pld Replacement Considerations

The datasheet confirms direct compatibility with GAL20V8 devices. It can replace most 24-pin combinatorial PAL devices. Verify pinout alignment before substitution.
