PALCE16V8H-15JC/4

Programmable Logic Device Pld Overview

The PALCE16V8H-15JC/4 is a Flash-based Programmable Logic Device (PLD) manufactured by Lattice Semiconductor. It features an advanced low-power, high-speed CMOS technology with electrically erasable floating-gate cells in the AND array. The device provides eight macrocells, each configurable as registered or combinatorial logic, supporting up to eight product terms per output. Key electrical parameters include a maximum propagation delay of 15 ns and a maximum operating frequency of 45.5 MHz. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an industrial temperature range from -40 °C to +85 °C.

Programmable Logic Device Pld Feature Summary

• Flash PLD architecture with electrically erasable AND array for reconfigurable logic
• Eight macrocells with flexible registered or combinatorial output configuration
• Pin and function compatible with standard 20-pin GAL devices
• High-speed CMOS technology with 15 ns propagation delay

Programmable Logic Device Pld Applications

• Direct replacement for legacy PAL16R8 logic circuits
• Complex combinational logic implementation in industrial systems
• Registered logic functions in data acquisition modules
• Address decoding and control logic in embedded controllers

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'JC/4' against official Lattice documentation to confirm package type and temperature grade. Ensure design files are programmed using compatible Lattice development tools that support the PALCE16V8 Flash architecture. Confirm power supply stability within the 4.75 V to 5.25 V range during operation.

Programmable Logic Device Pld Selection Notes

Select this component when a direct pin-compatible upgrade from older PAL devices is required without redesigning the PCB footprint. The Flash technology allows for unlimited reprogramming, making it suitable for prototyping and final production. Consider the 15 ns speed grade if timing constraints exceed those of slower -25 ns variants.

Programmable Logic Device Pld Part Context

The PALCE16V8 series represents Lattice's evolution of traditional Programmable Array Logic into electrically erasable Flash PLDs. This family maintains compatibility with industry-standard GAL pinouts while offering superior flexibility through non-volatile memory. The H variant denotes high-speed performance characteristics within the PALCE16V8 lineup.

Programmable Logic Device Pld Replacement Considerations

Functionally equivalent parts include the PALCE16V8Q-15JI5 and PALCE16V8L-15JIT. Verify package compatibility, as these alternatives may use different lead forms such as J-leads or gull-wing configurations compared to the DIP or PLCC packages typical of the JC suffix.
