PALCE16V8H-5JC/5

Programmable Logic Device Pld Overview

The PALCE16V8H-5JC/5 is an electrically erasable programmable logic device (EEPAL) manufactured by Lattice Semiconductor. It utilizes advanced low-power, high-speed CMOS technology and features a universal macrocell architecture. The device provides 18 inputs and 8 I/O lines within a 20-pin PLCC package. Key electrical parameters include a maximum propagation delay of 5 ns for the -5 speed grade and a maximum clock frequency of 166 MHz. It supports reconfigurable logic with full testability, programmable output polarity, and register preload capabilities.

Programmable Logic Device Pld Feature Summary

• Electrically erasable CMOS technology enabling reconfigurable logic and 100% functional testing
• High-speed performance with 5 ns propagation delay and 166 MHz maximum clock frequency
• Universal macrocell architecture providing 8 dedicated outputs with programmable polarity
• Direct pin-compatible replacement for standard GAL16V8 devices

Programmable Logic Device Pld Applications

• Logic replacement for legacy GAL16V8 designs
• System control logic in industrial equipment
• Address decoding and bus arbitration circuits
• Interface translation between different logic families

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix /5 against manufacturer documentation to confirm package type and temperature range. Ensure compatibility with existing programming tools, as this EEPROM-based device requires specific voltage levels for erasure and rewriting compared to fuse-based PLDs. Check for RoHS compliance status if required by local regulations.

Programmable Logic Device Pld Selection Notes

Select the -5 speed grade when system timing requirements demand a 5 ns propagation delay. This device is suitable for designs requiring field reprogrammability without UV erasure. Compare input/output counts against the target application; the 18-in/8-out configuration is fixed. Consider power consumption differences between bipolar GALs and this CMOS implementation during initial design phases.

Programmable Logic Device Pld Part Context

This component belongs to the PALCE16V8 family of electrically erasable PAL devices. It serves as a modern alternative to traditional mask-programmable or OTP PALs, offering the flexibility of in-system reconfiguration while maintaining compatibility with older 20-pin GAL footprints. The family includes variants with different speed grades and package options.

Programmable Logic Device Pld Replacement Considerations

Functionally compatible with GAL16V8B and similar 20-pin GAL devices. Verify that the target system supports the higher voltage requirements for EEPROM programming operations. Ensure that the PCB layout accommodates any potential differences in pinout if substituting non-pin-compatible GAL variants.
