GAL16V8D-20QJNI

Programmable Logic Device Pld Overview

The GAL16V8D-20QJNI is a discontinued High Performance E2CMOS PLD from the GAL®16V8 series. It features 16 inputs, 8 outputs, and 8 macrocells with a maximum propagation delay of 20 ns. The device operates on a 4.5 V to 5.5 V supply within an industrial temperature range of -40°C to 85°C. Packaged in a lead-free 20-pin PLCC, it utilizes Electrically Erasable floating gate technology for reprogrammability.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Offers high-speed electrical erasure (<100ms) and 20-year data retention.
• Reconfigurable Architecture: Supports Registered, Complex, and Simple OLMC modes via software configuration.
• Active Pull-ups: Features active pull-ups on all pins to minimize latch-up potential.
• Electronic Signature: Includes 64 bits of user-reprogrammable memory for identification.

Programmable Logic Device Pld Applications

• DMA Control
• State Machine Control
• High Speed Graphics Processing
• Standard Logic Speed Upgrade

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification (PCN) #13-10. Lattice Semiconductor has ceased production. Verification of availability requires checking secondary market distributors or authorized liquidation partners like Rochester Electronics. No new units are manufactured by the original equipment manufacturer.

Programmable Logic Device Pld Selection Notes

Select this part only for legacy system maintenance where specific pinouts and timing characteristics are required. The 20 ns speed grade (-20) must be verified against system clock requirements. Ensure design tools support the GAL16V8 architecture for compiling registered or combinatorial logic configurations.

Programmable Logic Device Pld Part Context

The GAL16V8D-20QJNI belongs to the GAL16V8D product line, which emulates various 20-pin PAL architectures. The 'Q' suffix indicates Quarter Power consumption, and 'JN' denotes a lead-free Plastic Leadless Chip Carrier package. This device represents the final generation of generic array logic before broader FPGA adoption.

Programmable Logic Device Pld Replacement Considerations

No direct functional substitutes are listed in the official documentation. Designers should evaluate modern CPLDs or FPGAs that offer similar I/O counts and pin compatibility. Verify that replacement devices support the necessary voltage levels and package dimensions for existing PCB footprints.
