ISPGAL22V10AV-23LN

Programmable Logic Device Pld Overview

The ispGAL22V10AV-23LN is a discontinued Simple Programmable Logic Device (SPLD) manufactured by Lattice Semiconductor. It utilizes E2CMOS technology for in-system programming via IEEE 1532 and boundary scan testing per IEEE 1149.1. Designed for 3.3V operation, it features a 2.3ns maximum propagation delay and supports up to 455 MHz frequency. The device includes ten Output Logic Macrocells with variable product terms, hot-socketing capability, and individually programmable output slew rates.

Programmable Logic Device Pld Feature Summary

• In-system programmable using IEEE 1532 compliant interface
• IEEE 1149.1 boundary scan testability support
• Hot-socketing tolerant for active signal environments
• Programmable output slew rate control

Programmable Logic Device Pld Applications

• DMA control
• State machine control
• High speed graphics processing
• Software-driven hardware configuration

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued under Product Change Notification #09-10. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Confirm the specific package type, as QFN variants were previously discontinued via PCN #13A-08.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with the ispGAL22LV10 or GAL22V10 families is required. Ensure the design accommodates the 3.3V core voltage and verify that the 2.3ns speed grade meets timing constraints. Consider modern SPLD replacements if new procurement is necessary due to discontinuation status.

Programmable Logic Device Pld Part Context

The ispGAL22V10AV-23LN belongs to the ispGAL22V10A family, which offers low-power E2CMOS logic. The 'AV' suffix indicates 3.3V supply voltage operation, while '-23' denotes the 2.3ns speed grade. The 'LN' suffix identifies the 32-pin Quad Flat No-lead (QFN) package variant.

Programmable Logic Device Pld Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Lattice Semiconductor for current equivalent devices suitable for replacing discontinued ispGAL series components.
