GAL22V10D-25LJI

Programmable Logic Device Pld Overview

The GAL22V10D-25LJI is a discontinued Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Lattice Semiconductor. It utilizes E2CMOS technology and features 22 I/O pins, 10 macrocells, and a maximum propagation delay of 25 ns. The device operates within a supply voltage range of 4.75 V to 5.25 V for commercial grade or 4.50 V to 5.50 V for industrial grade, with an operating temperature range of -40°C to +85°C. It is housed in a 28-pin PLCC package.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Offers high-speed electrical erasure (<100ms), reprogrammable cells, and over 20 years of data retention.
• Flexible Architecture: Features 10 Output Logic Macrocells (OLMCs) configurable as registered or combinatorial I/O with individual polarity control.
• Active Pull-ups: Built-in active pull-ups 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

Programmable Logic Device Pld Procurement Notes

All devices in the GAL22V10 product line have been officially discontinued per Product Change Notifications PCN#09-10 and PCN#13-10. Verification of current availability requires direct contact with authorized distributors or secondary market suppliers, as standard manufacturing channels no longer stock this component.

Programmable Logic Device Pld Selection Notes

Select the GAL22V10D-25LJI only if legacy system compatibility with standard 22V10 fuse maps is required. Ensure design constraints accommodate the 25 ns propagation delay and 5V logic levels. Verify that the 28-pin PLCC footprint matches existing PCB layouts, as surface-mount transition may be necessary for new implementations.

Programmable Logic Device Pld Part Context

This part belongs to the GAL22V10 family of Generic Array Logic devices. It is functionally and parametrically compatible with standard bipolar and UVCMOS 22V10 devices. The 'I' suffix denotes Industrial temperature rating, while 'LJ' indicates a Lead-Free PLCC package.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the discontinuation status. Designers should evaluate modern CPLD or FPGA alternatives from Lattice or other manufacturers that offer pin-compatible packages and similar logic density.
