ISPGAL22V10AV-75LNNI

Programmable Logic Device Pld Overview

The ISPGAL22V10AV-75LNNI is a discontinued Simple Programmable Logic Device (SPLD) manufactured by Lattice Semiconductor. It utilizes E2CMOS technology with a 3.3V core supply and supports 3.3V LVCMOS I/O standards. The device features ten Output Logic Macrocells (OLMCs) within a 28-pin PLCC package, offering a maximum propagation delay of 7.5 ns and a maximum operating frequency of 100 MHz. Key capabilities include In-System Programming via IEEE 1532, boundary scan testability per IEEE 1149.1, hot-socketing tolerance, and individually programmable output slew rates.

• High Speed Graphics Processing
• Software-driven Hardware Configuration

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor under Product Change Notification (PCN) #09-10. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer inventory. Designers must confirm the specific package variant (Lead-Free QFN vs. PLCC) as legacy stock may vary in packaging compliance.

Programmable Logic Device Pld Selection Notes

Select this part only if existing designs require functional compatibility with GAL22V10 or ispGAL22LV10 families. The 'AV' suffix indicates a 3.3V core voltage, while '75' denotes the 7.5ns speed grade. Ensure the design accommodates the 28-pin PLCC footprint if sourcing original leaded packages, or verify pinout compatibility if migrating to the 32-pin QFNS alternative.

Programmable Logic Device Pld Part Context

The ISPGAL22V10AV-75LNNI belongs to the ispGAL22V10A family, which bridges the gap between traditional GAL devices and modern CPLDs. It offers low standby power consumption typical of CMOS processes while maintaining the ease of use associated with generic array logic. The device integrates an electronic signature register for identification and security features to prevent unauthorized readback of configuration data.

Programmable Logic Device Pld Replacement Considerations

Direct replacements are unavailable due to discontinuation. Consider the ispGAL22LV10 series for similar functionality or migrate to Lattice's MachXO or CrossLink-NX FPGA families for new designs requiring equivalent logic density and I/O flexibility.
