GAL22V10D-7LJN

Programmable Logic Device Pld Overview

The Lattice Semiconductor GAL22V10D-7LJN is a discontinued Simple Programmable Logic Device (SPLD) based on the GAL22V10 architecture. It utilizes E2CMOS technology to provide high performance with a maximum propagation delay of 7 ns and a maximum operating frequency of 167 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 4.5 V to 5.5 V and supports commercial temperature ranges from 0°C to +75°C.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Combines CMOS process with Electrically Erasable floating gate technology for reconfigurable logic and fast erase times (<100ms).
• High Performance: Achieves a maximum propagation delay of 7 ns and a maximum clock frequency of 167 MHz with external feedback.
• Flexible Architecture: Contains ten OLMCs with variable product term access (8 to 16 terms per macrocell) and configurable registered or combinatorial modes.
• Active Pull-ups: All pins feature active pull-up circuits, ensuring floating inputs default to a TTL high state.

Programmable Logic Device Pld Applications

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

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued by Lattice Semiconductor as per Product Change Notification (PCN) #13-10. No new production units are available from the manufacturer. Verification of availability should be restricted to existing inventory held by distributors or third-party suppliers. Procurement efforts must account for the end-of-life status and potential limitations in long-term supply.

Programmable Logic Device Pld Selection Notes

Selection requires compatibility with standard 22V10 function, fuse map, and parametric specifications relative to bipolar and UVCMOS devices. Designers must verify that the 7 ns speed grade meets timing requirements for the target application. The PLCC package variant necessitates appropriate footprint design. Consideration of power consumption differences between Low Power (L) and Quarter Power (Q) variants is necessary if power constraints exist.

Programmable Logic Device Pld Part Context

The GAL22V10D-7LJN belongs to the GAL22V10 family of Generic Array Logic devices. This series was designed to offer higher performance than traditional bipolar 22V10 devices while maintaining pinout and logical compatibility. The 'D' suffix indicates the specific die revision, and 'LJN' denotes the Lead-Free PLCC package with commercial temperature rating. The family represents a transition point in Lattice's programmable logic portfolio utilizing E2 technology.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Due to the discontinued status, alternative sourcing relies on identifying functionally compatible devices from other manufacturers or newer Lattice families that maintain pin and logic compatibility.
