GAL22V10D-25LJN

Programmable Logic Device Pld Overview

The Lattice Semiconductor GAL22V10D-25LJN is a discontinued Simple Programmable Logic Device (SPLD) based on the GAL22V10 family. It utilizes E2CMOS technology and features ten Output Logic Macrocells (OLMCs). The device operates at a maximum propagation delay of 25 ns, corresponding to a maximum frequency of 33.3 MHz with external feedback. It supports a supply voltage range of 4.5 V to 5.5 V and functions within an ambient temperature range of -40°C to +85°C for industrial grade applications. The component is housed in a 28-pin PLCC package.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate technology enabling high-speed reprogramming (<100ms erase time) and over 20-year data retention.
• Flexible OLMCs: Ten configurable macrocells supporting registered or combinatorial I/O modes with individual polarity selection.
• Active Pull-ups: Built-in active pull-up circuits on all pins ensure floating inputs default to a logic high state.
• Electronic Signature: Includes 64 bits of user-reprogrammable 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

All devices in the GAL22V10 product line have been officially discontinued per Product Change Notifications (PCNs), including PCN#13-10 which references the GAL22V10D-25LJN. Verification of current availability requires checking authorized distributors or secondary market suppliers such as Rochester Electronics, as original manufacturer inventory is exhausted.

Programmable Logic Device Pld Selection Notes

Select this component only if legacy compatibility with standard bipolar or UVCMOS 22V10 fuse maps is required. The GAL22V10D-25LJN offers a 25 ns speed grade in a 28-PLCC package. Designers should account for the discontinuation status and consider modern replacements from the ispGAL22LV10 family for new designs requiring lower voltage operation or higher performance.

Programmable Logic Device Pld Part Context

The GAL22V10 series represents Lattice's high-performance Generic Array Logic devices utilizing E2CMOS technology. This specific part number denotes the commercial/industrial grade variant with a 25 ns delay specification packaged in Lead-Free Plastic Leaded Chip Carrier (PLCC) format. The 'N' suffix indicates lead-free packaging compliance.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers include GAL22V10D-25LJ and GAL22V10D-25QJN. For modern equivalents, the ispGAL22LV10 family provides functionally compatible options with improved speed grades and 3.3V operation capabilities.
