GAL22V10D-7LJNI

Programmable Logic Device Pld Overview

The GAL22V10D-7LJNI is a discontinued high-performance Electrically Erasable CMOS Programmable Logic Device (PLD) from Lattice Semiconductor. It utilizes E2CMOS technology to achieve a maximum propagation delay of 4 ns and an operating frequency of 250 MHz. The device features ten Output Logic Macrocells (OLMCs), active pull-ups on all pins, and reprogrammable cells with over 100 erase/write cycles and 20-year data retention. It operates at +4.75V to +5.25V for commercial grades and includes an electronic signature feature for identification.

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor as indicated in Product Change Notification PCN#09-10. Verification of current availability requires consulting authorized distributors or secondary market suppliers such as Rochester Electronics. Designers should confirm the specific package type and grade against legacy inventory lists before procurement.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with standard 22V10 fuse maps is required. The 'L' suffix indicates Low Power consumption (90 mA typical Icc), while 'J' denotes PLCC packaging and 'NI' specifies lead-free Industrial Grade construction. Ensure the design accounts for the 5V supply voltage range and TTL-compatible input levels.

Programmable Logic Device Pld Part Context

The GAL22V10 series represents Lattice's high-performance Generic Array Logic (GAL) devices. The D-7 variant specifically targets applications requiring faster switching speeds compared to slower speed grades like -10 or -15. This model sits within the broader GAL22V10 family, which offers varying power and speed options across DIP, PLCC, SOIC, and QFP packages.

Programmable Logic Device Pld Replacement Considerations

No direct functional replacements are listed in the provided documentation due to the discontinuation status. Users seeking modern equivalents should evaluate Lattice's ispMACH 4000ZE or ispGAL families, though these require architectural redesign and do not share pinouts or fuse maps.
