GAL22V10D-15QJ

Programmable Logic Device Pld Overview

The Lattice Semiconductor GAL22V10D-15QJ is a discontinued Simple Programmable Logic Device (SPLD) belonging to the GAL22V10 family. It utilizes E2CMOS technology and features ten Output Logic Macrocells (OLMCs). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40°C to +85°C for industrial applications. Key electrical parameters include a maximum propagation delay of 15 ns, a typical operating supply current of 75 mA to 90 mA, and a maximum clock frequency of 66.7 MHz with external feedback.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate technology enabling high-speed reprogramming (<100 ms erase time) and 20-year data retention.
• Flexible OLMCs: Ten configurable macrocells supporting registered or combinatorial modes with individual polarity control.
• Active Pull-ups: Built-in active pull-up circuits on all pins ensure inputs float to a logic high state when unconnected.
• 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

This component is officially discontinued per Product Change Notification (PCN) #13-10. No new units are manufactured by Lattice Semiconductor. Verification of authenticity is critical when sourcing from secondary markets, as availability is limited to existing inventory held by distributors or third-party suppliers.

Programmable Logic Device Pld Selection Notes

Designers should verify that the 15 ns speed grade meets system timing requirements, noting the maximum clock frequency drops to 66.7 MHz under external feedback conditions. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range and industrial temperature specifications (-40°C to +85°C). Consider modern replacements if long-term supply stability is required.

Programmable Logic Device Pld Part Context

The GAL22V10D-15QJ is part of the broader GAL22V10 product line, which includes variants with different speed grades (e.g., -4, -5, -7, -10, -20, -25) and package options such as DIP, PLCC, SOIC, and TQFP. All devices in this datasheet series share the same core architecture but differ in switching speeds and power consumption characteristics.

Programmable Logic Device Pld Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers seeking equivalent functionality should consult Lattice Semiconductor's current SPLD portfolios or compatible generic array logic devices from other manufacturers that maintain pinout and fuse-map compatibility.
