ISPGAL22V10AC-75LNI

Programmable Logic Device Pld Overview

The ispGAL22V10AC-75LNI is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, manufactured using low-voltage E2CMOS technology. It operates with a 1.8V core supply and supports 1.8V LVCMOS I/O standards. The device features ten Output Logic Macrocells (OLMCs), providing flexible combinatorial or registered logic configurations. Key electrical parameters include a maximum propagation delay of 7.5 ns and a typical standby power consumption of less than 300 µW. It supports In-System Programming via IEEE 1532 and boundary scan testing per IEEE 1149.1.

Programmable Logic Device Pld Feature Summary

• Low Voltage Operation: 1.8V core voltage with 1.8V LVCMOS I/O compatibility.
• High Performance: Maximum propagation delay of 7.5 ns for the -75 speed grade.
• In-System Programmability: Supports ISP via IEEE 1532 and boundary scan via IEEE 1149.1.
• Flexible Logic Architecture: Ten OLMCs with configurable product terms (8 to 16) and dedicated Asynchronous Reset/Synchronous Preset terms.

Programmable Logic Device Pld Applications

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

Programmable Logic Device Pld Procurement Notes

All devices in the ispGAL22V10A family, including the ISPGAL22V10AC-75LNI, have been officially discontinued by Lattice Semiconductor pursuant to Product Change Notification (PCN) #09-10. Verification of current availability should be conducted through authorized distributors or secondary market suppliers, as original manufacturer production has ceased.

Programmable Logic Device Pld Selection Notes

Select this component only if a 1.8V core supply and 1.8V I/O interface are required. The -75 suffix indicates a 7.5 ns maximum propagation delay. Ensure design compatibility with the 28-pin PLCC package (suffix 'J') and Industrial temperature grade (suffix 'I'). Verify that the target system can accommodate the discontinuation status and potential long-term supply constraints.

Programmable Logic Device Pld Part Context

The ispGAL22V10A family represents Lattice's low-voltage evolution of the classic GAL22V10 architecture. It combines CMOS performance with Electrically Erasable floating gate technology. The AC variant specifically targets 1.8V applications, offering functional compatibility with earlier GAL22LV10 and GAL22V10 devices while reducing power consumption significantly compared to bipolar counterparts.

Programmable Logic Device Pld Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers may consider migrating to modern Lattice FPGA or CPLD families for new designs due to the discontinued status of this SPLD line.
