GAL20V8B-25LJNI

Programmable Logic Device Pld Overview

The GAL20V8B-25LJNI is a discontinued Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Lattice Semiconductor. It utilizes high-performance E2CMOS technology and features an industrial temperature range of -40°C to +85°C. The device provides 10 dedicated inputs, 8 I/O lines, and 8 Output Logic Macrocells (OLMCs). It operates at a maximum propagation delay of 25 ns with a typical supply current of 75 mA in low-power configuration. The component is housed in a lead-free 28-pin Plastic Leadless Chip Carrier (PLCC) package.

Programmable Logic Device Pld Procurement Notes

This specific part number has been officially discontinued per Product Change Notification (PCN) #13-10. No new units are available from the manufacturer or authorized distributors. Verification of availability should be directed to secondary market suppliers such as Rochester Electronics, though stock cannot be guaranteed.

Programmable Logic Device Pld Selection Notes

Designers requiring this logic density should consider modern Lattice CPLD or FPGA families. When migrating, verify that the target device supports the required voltage levels and pinout compatibility if maintaining board footprint is necessary. The GAL20V8B series offers flexible OLMC configurations that may require architectural adjustments in newer devices.

Programmable Logic Device Pld Part Context

The GAL20V8B belongs to the Generic Array Logic (GAL) family, which emulates standard PAL architectures. This specific variant represents the industrial grade version with a 25 ns speed grade. The 'LJ' suffix indicates a Plastic Leadless Chip Carrier package, while 'NI' denotes lead-free construction compliant with environmental standards active during its production lifecycle.

Programmable Logic Device Pld Replacement Considerations

Direct replacement parts are not available due to discontinuation. Refer to PCN #13-10 for official status. Potential functional equivalents include other Lattice GAL20V8 variants or modern CPLDs, but pin-to-pin compatibility is not guaranteed across different generations.
