M4A5-32/32-12VNI

Complex Programmable Logic Devices Overview

The M4A5-32/32-12VNI is a member of the Lattice ispMACH 4A family, specifically the 5-V E2CMOS CPLD series. It features 32 macrocells and 32 user I/Os housed in a 44-pin PLCC package. The device supports JTAG (IEEE 1149.1) for in-system programming and boundary scan testing. Key electrical parameters include a maximum propagation delay ($t_{PD}$) of 12 ns and a maximum count frequency ($f_{CNT}$) of 182 MHz. It operates within a commercial temperature range of 0°C to +70°C with a supply voltage of 5 V.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'VNI' against official Lattice documentation to confirm package type and temperature grade. Confirm end-of-life status and availability through authorized distributors as this component may be discontinued or subject to limited production runs.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 32 macrocells with 5-V I/O compatibility. Ensure the application fits within the 12 ns speed grade constraints. Consider the 44-pin PLCC package for prototyping or legacy board designs. Verify that the 5-V supply voltage aligns with the system power requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A family, which blends ispLSI 2000 and ispMACH 4A architectures. It offers high density and performance with low power consumption compared to older GAL devices. The family supports densities from 32 to 512 macrocells across various packages.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A5-32/32 variants with different speed grades (e.g., -10, -7). Cross-family migration to ispMACH 4000V/Z may require architectural adjustments due to differences in macrocell structure and I/O capabilities.
