GAL22V10D-15QPN

Programmable Logic Device Pld Overview

The Lattice Semiconductor GAL22V10D-15QPN is a discontinued Simple Programmable Logic Device (SPLD) based on the GAL22V10 architecture. It utilizes E2CMOS technology to provide reconfigurable logic with ten output macrocells. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum propagation delay of 15 ns, corresponding to a maximum clock frequency of 83.3 MHz. It features active pull-ups on all pins and includes an electronic signature for identification. The component is housed in a 24-pin Plastic DIP package.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate process allowing high-speed reprogramming (<100ms erase time) and data retention exceeding 20 years.
• Output Logic Macrocells: Contains ten OLMCs with variable product term access (8 to 16 terms per cell) supporting registered or combinatorial modes.
• Active Pull-ups: Built-in active pull-up circuits on all input and I/O pins ensure defined logic states for unused inputs.
• Electronic Signature: Includes 64 bits of user-programmable memory for device identification, revision tracking, or inventory control.

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 is officially discontinued by Lattice Semiconductor as indicated in Product Change Notification PCN#09-10. Availability is restricted to existing inventory held by distributors or third-party suppliers. Verification of authenticity and physical condition is required due to the end-of-life status. No new production units are manufactured.

Programmable Logic Device Pld Selection Notes

Select this component only if legacy compatibility with standard bipolar or UVCMOS 22V10 devices is required. The -15 speed grade offers a 15 ns maximum propagation delay suitable for moderate-speed applications. Ensure the design accommodates the 24-pin PDIP package and verify that the 10 macrocell capacity meets the logic density requirements.

Programmable Logic Device Pld Part Context

The GAL22V10D-15QPN belongs to the GAL22V10 family of Generic Array Logic devices. This series was designed to replace older bipolar PAL devices with lower power consumption CMOS alternatives while maintaining pinout and fuse-map compatibility. The 'D' suffix denotes the specific die variant optimized for E2CMOS processing.

Programmable Logic Device Pld Replacement Considerations

No direct functional replacements are listed in the provided documentation. As the entire GAL22V10 product line is discontinued, alternative solutions require redesigning the logic into modern CPLDs or FPGAs from Lattice or other manufacturers.
