GAL16V8D-20QJI

Programmable Logic Device Pld Overview

The GAL16V8D-20QJI is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features 16 inputs and 8 outputs in a 20-pin PLCC package. The device supports a maximum propagation delay of 20 ns and a maximum clock frequency of 41.6 MHz. It includes eight Output Logic Macrocells (OLMCs) with reconfigurable modes: registered, complex, and simple. Key specifications include active pull-ups on all pins, programmable output polarity, and an electronic signature for identification.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: High-speed electrical erasure (<100ms) and 20-year data retention.
• Reconfigurable OLMCs: Supports Registered, Complex, and Simple logic modes via architecture bits.
• Active Pull-Ups: Integrated active pull-ups on all pins to minimize latch-up potential.
• Electronic Signature: 64-bit reprogrammable memory for user-defined identification data.

Programmable Logic Device Pld Applications

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

Programmable Logic Device Pld Procurement Notes

All devices in the GAL16V8 product line are officially discontinued per Product Change Notifications PCN#06-07 and PCN#13-10. The GAL16V8D-20QJI is no longer manufactured or distributed by Lattice Semiconductor. Verification of availability should be restricted to third-party surplus inventory sources, as original manufacturer supply is terminated.

Programmable Logic Device Pld Selection Notes

Designers requiring equivalent functionality must evaluate modern Lattice SPLD or FPGA alternatives due to the discontinuation of the GAL16V8 series. Selection criteria should focus on pin compatibility, macrocell configuration requirements (registered vs. combinatorial), and operating temperature ranges compatible with the target application environment.

Programmable Logic Device Pld Part Context

The GAL16V8D-20QJI belongs to the GAL16V8 family of Generic Array Logic devices. The 'D' suffix indicates the low-power variant, '20' denotes the 20 ns speed grade, 'Q' signifies Quarter Power consumption, and 'J' identifies the Plastic Leadless Chip Carrier (PLCC) package. This component represents a legacy electrically erasable programmable logic solution.

Programmable Logic Device Pld Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. Users must consult Lattice Semiconductor's current SPLD or FPGA portfolios for functional equivalents, as the entire GAL16V8 line has been discontinued.
