M4A5-32/32-12VNI48

Complex Programmable Logic Devices Overview

The M4A5-32/32-12VNI48 is a member of the Lattice ispMACH 4A family, specifically the 5-V commercial-grade CPLD. It features 32 macrocells and 32 user I/Os housed in a 48-pin Thin Quad Flat Pack (TQFP) package. The device operates at a maximum frequency of 182 MHz with a typical propagation delay of 12 ns. It utilizes E2CMOS technology for non-volatile configuration via JTAG. Key architectural elements include a central switch matrix, dedicated input registers, and flexible macrocell configurations supporting synchronous or asynchronous modes.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'VNI48' against official Lattice documentation to confirm the exact package type and temperature grade. Ensure compatibility with existing design tools for the ispMACH 4A family. Check for lead-free status if required by environmental regulations.

Complex Programmable Logic Devices Selection Notes

Select this component when 32 macrocells are sufficient for the design. The 5-V operation makes it suitable for legacy systems requiring direct interfacing with 5-V logic without level shifting. Consider the 48-pin TQFP package constraints for PCB layout.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A family, which offers high performance and flexibility. The 'M4A5' designation indicates the 5-V variant. The '-12' speed grade corresponds to the 12 ns delay specification. The 'VNI48' suffix identifies the specific package and thermal characteristics.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A5-32 variants with different speed grades or packages. Cross-family migration may require significant redesign due to architectural differences.
