GAL18V10B-10LJ

Programmable Logic Device Pld Overview

The GAL18V10B-10LJ is a discontinued High Performance E2CMOS PLD from Lattice Semiconductor. It features a 7.5 ns maximum propagation delay and an Fmax of 111 MHz. The device utilizes Electrically Erasable floating gate technology for reprogrammability, with 100 erase/write cycles and over 20 years data retention. It operates at +4.75 to +5.25 V with a typical supply current of 75 mA. The architecture includes ten Output Logic Macrocells (OLMCs) compatible with the standard 22V10 design, supporting registered and combinatorial I/O modes.

Programmable Logic Device Pld Procurement Notes

All devices in this datasheet have been officially discontinued per Product Change Notifications PCN#06-07 and PCN#13-10. The GAL18V10B-10LJ is no longer manufactured by Lattice Semiconductor. Verification of availability requires checking secondary market distributors or Rochester Electronics for existing inventory, as original production has ceased.

Programmable Logic Device Pld Selection Notes

Designers should note that the GAL18V10B-10LJ is obsolete. Selection requires identifying equivalent legacy SPLDs or migrating to modern Lattice CPLD/FPGA families. Verify pin compatibility if replacing with other GAL18V10 variants, but confirm that newer technologies offer sufficient logic density and power efficiency for current requirements.

Programmable Logic Device Pld Part Context

The GAL18V10B-10LJ belongs to the GAL18V10 series of Generic Array Logic devices. It shares the same functional architecture as the GAL18V10B-7LJ, -15LJ, and -20LJ, differing primarily in speed grade. The 'LJ' suffix indicates a Plastic Leadless Chip Carrier (PLCC) package with 20 pins. This series was designed to provide a flexible, low-power alternative to bipolar PALs.

Programmable Logic Device Pld Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. Discontinued status necessitates evaluating modern Lattice CPLDs or generic SPLDs with similar pin counts and logic capacity.
