ISPGAL22V10AV-75LSN

Programmable Logic Device Pld Overview

The ISPGAL22V10AV-75LSN is a Simple Programmable Logic Device (SPLD) from Lattice Semiconductor's ispGAL22LV10 family. It utilizes E2CMOS technology to provide reconfigurable logic in a 28-pin PLCC package. The device features 10 macrocells and supports a maximum propagation delay of 7.5 ns, with a typical operating frequency of approximately 133 MHz. Designed for low-voltage applications, it operates at 3.3 V with active pull-ups on all pins, offering significant power reduction compared to bipolar equivalents while maintaining functional compatibility with standard 22V10 devices.

Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'SN' against official Lattice documentation to confirm package type and temperature grade. Confirm RoHS compliance status as older variants may differ. Check current product lifecycle status, as mature GAL/ispGAL families often face discontinuation or limited availability.

Programmable Logic Device Pld Selection Notes

Select this component when a drop-in replacement for legacy bipolar 22V10 devices is required with lower power consumption. Ensure the system voltage supports 3.3 V operation. Verify that the 10-macrocell capacity meets the logic density requirements for the target application.

Programmable Logic Device Pld Part Context

This part belongs to the ispGAL22LV10 family, which extends the classic GAL22V10 architecture with In-System Programming capabilities. It bridges the gap between traditional mask-programmed PALs and complex CPLDs, offering flexibility for small-scale logic designs without the complexity of FPGA tools.

Programmable Logic Device Pld Replacement Considerations

Functionally compatible with GAL22V10D and GAL22V10B series devices. Electrical differences include supply voltage (3.3 V vs 5 V) and pin drive characteristics due to CMOS technology. Verify voltage levels on connected interfaces before substitution.
