GAL22V10D-25QJN

Programmable Logic Device Pld Overview

The GAL22V10D-25QJN is a discontinued Electrically Erasable Programmable Logic Device (EEPROM-based PLD) manufactured by Lattice Semiconductor. It features 10 macrocells, 22 I/O pins, and a maximum propagation delay of 25 ns. The device utilizes E2CMOS technology with active pull-ups on all pins and operates at 5V. It is housed in a 28-pin PLCC package. Product Change Notifications confirm discontinuation for this part number.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: High-speed electrical erase (<100ms), 100 erase/write cycles, and >20-year data retention.
• Flexible Architecture: 10 Output Logic Macrocells (OLMCs) with configurable registered or combinatorial modes.
• Active Pull-ups: Built-in active pull-ups on all pins to prevent floating inputs.
• Electronic Signature: 64-bit reprogrammable memory for user-defined identification data.

Programmable Logic Device Pld Applications

• DMA Control
• State Machine Control
• High Speed Graphics Processing

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per PCN #13-10. No new production is available from the manufacturer. Verification of authenticity is critical when sourcing from third-party distributors due to potential obsolescence risks.

Programmable Logic Device Pld Selection Notes

Select only if legacy compatibility with standard 22V10 fuse maps is required. Consider modern FPGA/CPLD alternatives for new designs as this part is no longer supported. Verify voltage levels (5V) and package type (PLCC-28) match existing board layouts.

Programmable Logic Device Pld Part Context

Part of the GAL22V10 family, which includes variants like GAL22V10D-7LP and GAL22V10D-10LJ. All devices in this datasheet were discontinued around September 2010.

Programmable Logic Device Pld Replacement Considerations

No direct public substitutes are listed. Modern equivalents may include Lattice MachXO or ICE40 series FPGAs, though pinouts and logic architecture differ significantly.

Programmable Logic Device Pld FAQ

What is the maximum operating frequency?

The maximum clock frequency without feedback is 38.5 MHz for the -25 speed grade.

Does the device support asynchronous reset?

Yes, it includes an Asynchronous Reset (AR) product term that sets all registers to zero when asserted.

Is the device RoHS compliant?

The 'N' suffix indicates lead-free packaging, but the datasheet notes general RoHS non-compliance for older stock; verify specific batch compliance.
