GAL22V10D-20LPI

Programmable Logic Device Pld Overview

The GAL22V10D-20LPI is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features ten output logic macrocells and supports a maximum propagation delay of 20 ns with an operating frequency up to 83.3 MHz. The device operates on a 5V supply (4.5V to 5.5V for industrial grade) within a -40°C to +85°C temperature range. Packaged in a 28-pin PLCC, it includes active pull-ups, asynchronous reset, synchronous preset, and a user-programmable electronic signature.

Programmable Logic Device Pld Feature Summary

• Flexible I/O Configuration: Ten Output Logic Macrocells (OLMCs) configurable as registered or combinatorial outputs with individual polarity control.
• Active Pull-Ups: Built-in active pull-up circuits on all pins ensure inputs float to a TTL high level when unconnected.
• Electronic Signature: Integrated 64-bit reprogrammable memory for user-defined identification codes or revision tracking.

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 PCN#09-10. Verification of availability requires checking secondary market distributors or authorized liquidation partners like Rochester Electronics. Ensure strict adherence to the specified industrial temperature range (-40°C to +85°C) and voltage limits during any legacy system integration.

Programmable Logic Device Pld Selection Notes

Select this part only if the design specifically requires the GAL22V10 pinout and logic density. Verify that the 20 ns speed grade meets the system timing requirements, as faster variants (e.g., -7LP) or slower variants exist. Confirm compatibility with existing programming tools supporting the GAL22V10 JEDEC fuse map.

Programmable Logic Device Pld Part Context

The GAL22V10D series represents Lattice's high-performance CMOS implementation of the standard 22V10 generic array logic architecture. It offers significant power reduction compared to bipolar equivalents while maintaining full functional and parametric compatibility with industry-standard UVCMOS devices.
