GAL22V10D-20LJNI

Programmable Logic Device Pld Overview

The GAL22V10D-20LJNI is a discontinued Electrically Erasable Programmable Logic Device (EEPROM-based PLD) manufactured by Lattice Semiconductor. It features 10 output logic macrocells and a maximum propagation delay of 20 ns. The device utilizes E2CMOS technology, allowing for high-speed electrical erasure in under 100 ms and data retention exceeding 20 years. It operates within a supply voltage range of +4.50 V to +5.50 V and supports an industrial temperature range of -40°C to +85°C. The component is housed in a lead-free 28-pin PLCC package.

Programmable Logic Device Pld Procurement Notes

This product has been officially discontinued per PCN #13-10 issued by Lattice Semiconductor. Verification of availability should focus on surplus distributors or secondary market sources, as original manufacturer production has ceased. Compliance with RoHS standards is indicated by the 'Lead-Free' designation in the ordering suffix.

Programmable Logic Device Pld Selection Notes

Select this component only if legacy compatibility with standard bipolar or UVCMOS 22V10 devices is required. Ensure the design accommodates the 20 ns propagation delay limit and the specific 28-PLCC footprint. Verify that the industrial temperature grade (-40°C to +85°C) meets the operational environment requirements.

Programmable Logic Device Pld Part Context

The GAL22V10D series represents Lattice's high-performance Generic Array Logic devices built on E2CMOS technology. This specific part number denotes the Industrial grade variant with a 20 ns speed grade, packaged in a Lead-Free Plastic Leaded Chip Carrier (PLCC). It serves as a drop-in replacement for older bipolar 22V10 architectures while offering lower power consumption and reconfigurability.

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 consult Lattice Semiconductor for modern FPGA or CPLD equivalents suitable for new designs.
