GAL22V10D-15LJNI

Programmable Logic Device Pld Overview

The GAL22V10D-15LJNI is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features 10 Output Logic Macrocells (OLMCs), 22 inputs, and 10 outputs within a 28-pin PLCC package. The device operates at a maximum propagation delay of 15 ns and supports a supply voltage range of 4.75 V to 5.25 V for commercial grade applications. Key specifications include active pull-ups on all pins, asynchronous reset, synchronous preset capabilities, and an electronic signature feature.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate technology with high-speed electrical erasure (<100ms) and 20-year data retention.
• Flexible OLMCs: Ten output logic macrocells 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 TTL high state.
• Electronic Signature: Includes 64 bits of reprogrammable memory for user-defined identification codes or revision numbers.

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, including the GAL22V10D-15LJNI, have been officially discontinued per Product Change Notification (PCN). Verification of current availability requires checking authorized distributors or secondary market suppliers, as original manufacturer stock is no longer produced.

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 28-pin PLCC package and 5V supply requirements. Consider that the device is obsolete; verify end-of-life status and potential obsolescence risks before finalizing the design.

Programmable Logic Device Pld Part Context

The GAL22V10D-15LJNI belongs to the GAL22V10D series, which offers high-performance CMOS processing compared to older bipolar counterparts. The 'L' indicates Low Power consumption, 'J' denotes the PLCC package, 'N' signifies lead-free packaging, and 'I' specifies the Industrial temperature grade (-40°C to +85°C).

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the discontinuation of the entire product line. Designers should evaluate modern SPLD or CPLD alternatives from Lattice or other manufacturers that offer similar pin counts and functionality.
