GAL22V10D-7LJI

Programmable Logic Device Pld Overview

The GAL22V10D-7LJI is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features 22 I/O pins and 10 Output Logic Macrocells (OLMCs). 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 within a supply voltage range of 4.75 V to 5.25 V for commercial grades. The component is housed in a 28-pin PLCC package and includes active pull-ups on all pins.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate process enabling reconfigurable logic with high-speed electrical erasure (<100ms) and 20-year data retention.
• Flexible OLMC Architecture: Ten output logic macrocells allow configurable registered or combinatorial modes with individual product-term driven tri-state control.
• Active Pull-Ups: Built-in active pull-ups on all pins ensure floating inputs default to a TTL high state, improving noise immunity.
• Electronic Signature: Includes 64 bits of user-programmable memory for 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 part number has been officially discontinued by Lattice Semiconductor per Product Change Notification (PCN) #09-10. Availability is limited to existing inventory or secondary market sources. Verification of the specific ordering suffix 'I' confirms Industrial Grade temperature rating (-40°C to +85°C), while 'J' indicates the PLCC package type.

Programmable Logic Device Pld Selection Notes

Select this component only if legacy 22V10 compatibility and electrically erasable programmability are required. The -7 speed grade provides a 7.5 ns maximum propagation delay. Ensure designs account for the Industrial Grade operating temperature range and verify that the 28-PLCC footprint matches the target PCB layout.

Programmable Logic Device Pld Part Context

The GAL22V10D series represents a high-performance Generic Array Logic (GAL) device family. The GAL22V10D-7LJI specifically denotes the 7 ns speed grade, PLCC package, and Industrial temperature variant. It is fully function, fuse-map, and parametric compatible with standard bipolar and UVCMOS 22V10 devices.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers include GAL22V10D-7LJNI (Lead-Free PLCC) and GAL22V10D-10LJI (10 ns speed grade). Other speed grades within the same package and grade may serve as functional replacements depending on timing requirements.
