GAL22V10D-7LPN

Programmable Logic Device Pld Overview

The GAL22V10D-7LPN is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features ten Output Logic Macrocells (OLMCs), active pull-ups on all pins, and an electronic signature for identification. The device operates at a maximum propagation delay of 7.5 ns with a typical supply current of 90 mA. It supports commercial temperature ranges (0°C to +75°C) and is housed in a lead-free Plastic DIP-24 package.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate architecture enabling high-speed reprogramming (<100ms erase time) and 20-year data retention.
• Flexible OLMCs: Ten macrocells with variable product term access (8 to 16 terms per pin) supporting registered or combinatorial I/O modes.
• 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-programmable memory for revision control or identification.

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 has been officially discontinued by Lattice Semiconductor as indicated in Product Change Notification (PCN) #13-10. Availability is restricted to existing inventory or third-party distributors. Verification of the specific 'N' suffix confirms lead-free packaging compliance, but functional replacement requires evaluating modern SPLD alternatives due to end-of-life status.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with standard 22V10 fuse maps is required. The '-7' speed grade specifies a maximum propagation delay of 7.5 ns. Ensure designs account for the PDIP-24 through-hole package dimensions. Verify that the application environment remains within the commercial operating temperature range of 0°C to +75°C.

Programmable Logic Device Pld Part Context

The GAL22V10D series represents Lattice's high-performance Generic Array Logic devices based on E2CMOS technology. This family provides parametric and functional compatibility with older bipolar and UVCMOS 22V10 devices while offering significantly lower power consumption and reprogrammability. The 'D' suffix denotes the specific device variant within the GAL22V10 family.

Programmable Logic Device Pld Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Lattice Semiconductor for recommended modern equivalents or cross-reference with other SPLD manufacturers offering compatible pinouts and logic density.
