GAL22V10D-5LJN

Programmable Logic Device Pld Overview

The GAL22V10D-5LJN is a discontinued high-performance Electrically Erasable Programmable Logic Device (PLD) from Lattice Semiconductor. It utilizes E2CMOS technology to achieve a maximum propagation delay of 5 ns and a maximum operating frequency of 200 MHz. The device features ten Output Logic Macrocells (OLMCs), active pull-ups on all pins, and an electronic signature for identification. It operates within a supply voltage range of 4.75 V to 5.25 V at commercial temperatures (0°C to +75°C). The component is housed in a lead-free 28-pin PLCC package.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Offers reconfigurable logic with high-speed electrical erasure (<100ms) and 20-year data retention.
• Performance: Maximum propagation delay of 5 ns and Fmax of 200 MHz with no feedback.
• Architecture: Contains ten OLMCs with variable product term access (8 to 16 terms per macrocell).
• Compatibility: Fully function, fuse-map, and parametric compatible with standard bipolar and UVCMOS 22V10 devices.

Programmable Logic Device Pld Applications

• DMA Control
• State Machine Control
• High Speed Graphics Processing
• Standard Logic Speed Upgrade

Programmable Logic Device Pld Procurement Notes

All devices in the GAL22V10 family have been officially discontinued per Product Change Notification (PCN) #13-10. The GAL22V10D-5LJN is no longer manufactured or supported by Lattice Semiconductor. Verification of current availability requires checking third-party distributors for remaining inventory, as original supply has ceased.

Programmable Logic Device Pld Selection Notes

Select this component only if legacy compatibility with standard 22V10 architectures is required. The -5 speed grade provides a 5 ns maximum propagation delay. Ensure designs account for the 5V supply requirement and the specific pinout of the 28-PLCC package. Note that the 'N' suffix indicates a lead-free package option.

Programmable Logic Device Pld Part Context

The GAL22V10D-5LJN belongs to the GAL22V10D series, which represents the high-performance variant of the generic array logic family. This series combines CMOS low power consumption with electrically erasable programmability, distinguishing it from older one-time programmable bipolar counterparts.

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 migration.

Programmable Logic Device Pld FAQ

What is the maximum clock frequency for the GAL22V10D-5LJN?

The maximum clock frequency (Fmax) is 200 MHz when configured with no feedback.

How many product terms are available for each Output Logic Macrocell?

The number of product terms varies by pin: two OLMCs have 8 terms, two have 10, two have 12, two have 14, and two have 16 terms.

Does the device support asynchronous reset?

Yes, the GAL22V10 includes a dedicated product term for Asynchronous Reset (AR) that sets all registers to zero when asserted.
