GAL22V10D-7LJ

Programmable Logic Device Pld Overview

The GAL22V10D-7LJ is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features 22 I/O pins and 10 macrocells within a 28-pin PLCC package. The device operates at a maximum propagation delay of 7.5 ns and supports a maximum clock frequency of 166 MHz with internal feedback. It functions on a 5V supply voltage (4.75V to 5.25V) and includes active pull-ups on all pins for improved noise immunity.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate technology enabling high-speed reprogramming (<100ms erase time) and 20-year data retention.
• High Performance: Maximum propagation delay of 7.5 ns and Fmax of 166 MHz with internal feedback.
• Flexible Architecture: 10 Output Logic Macrocells (OLMCs) configurable as registered or combinatorial I/O with individual polarity control.
• Active Pull-ups: Built-in active pull-ups on all pins ensure floating inputs default to a logic high state.

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. Verification of availability requires checking secondary market distributors or authorized stockists for remaining inventory. Ensure the specific ordering suffix matches the required package type and temperature grade before procurement.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with standard 22V10 fuse maps is required. Verify that the 7.5 ns speed grade meets the system timing requirements. Consider the 28-pin PLCC package constraints for PCB layout. Industrial grade variants are available with different suffixes if extended temperature ranges are needed.

Programmable Logic Device Pld Part Context

The GAL22V10D-7LJ belongs to the GAL22V10D series, which offers high-performance CMOS logic in a generic array structure. It is fully function, fuse-map, and parametric compatible with older bipolar and UVCMOS 22V10 devices. The 'LJ' suffix indicates a Lead-Free PLCC package with Commercial temperature range specifications.
