ISPGAL22V10AB-75LN

Programmable Logic Device Pld Overview

The ISPGAL22V10AB-75LN is a Simple Programmable Logic Device (SPLD) from the ispGAL22V10 family, manufactured by Lattice Semiconductor. It utilizes E2CMOS technology to provide electrically erasable and programmable logic capabilities within a standard 22V10 pinout architecture. The device features ten output macrocells and supports in-system programming via the ISP interface. Key electrical parameters include a maximum propagation delay of 7.5 ns and a maximum operating frequency of 133 MHz. It operates with a supply voltage range typical for 5V CMOS logic devices.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate technology allowing rapid reprogramming without UV exposure.
• In-System Programming (ISP): Supports serial programming directly on the PCB, eliminating the need for socketed programmers.
• Standard Compatibility: Functionally and parametrically compatible with bipolar and UVCMOS GAL22V10 devices.
• High Performance: Achieves a maximum propagation delay of 7.5 ns and a maximum frequency of 133 MHz.

Programmable Logic Device Pld Applications

• State Machine Control
• DMA Controller Interfaces
• Address Decoding
• Bus Arbitration

Programmable Logic Device Pld Part Context

The ISPGAL22V10AB-75LN belongs to the ispGAL22V10 family, which represents the evolution of the classic GAL22V10 architecture into an electrically programmable format. This family bridges legacy discrete logic designs with modern reconfigurable requirements, maintaining pin compatibility while adding non-volatile, reprogrammable storage capabilities through Lattice's proprietary E2CMOS process.

Programmable Logic Device Pld Replacement Considerations

Direct replacements must match the 28-pin PLCC package and the 22V10 logical structure. Equivalent parts include the GAL22V10B series for fixed logic or other ispGAL22V10 variants with equal or faster speed grades (e.g., -100). Verify that the replacement supports ISP programming if in-circuit updates are required.
