M4A5-128/64-10VNI

Complex Programmable Logic Devices Overview

The M4A5-128/64-10VNI is a 5-V ispMACH 4A CPLD featuring 128 macrocells and 64 user I/Os. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides a maximum propagation delay (tPD) of 10 ns and supports a maximum count frequency (fCNT) of 182 MHz. It utilizes an E2CMOS process for in-system programming via JTAG (IEEE 1149.1). The component is housed in a 100-pin TQFP package.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'VNI' against the manufacturer's current datasheet to confirm package type, temperature grade, and lead-free status. Ensure compatibility with existing design tools and verify that the 5-V operation aligns with system power requirements.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring high pin-out retention and fixed timing guarantees. The 1:1 macrocell-to-I/O ratio allows direct mapping of logic to pins. Consider the 10 ns speed grade if higher throughput than the -12 grade is needed while maintaining 5-V compatibility.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4A family, which combines features from previous generations. It offers densities from 32 to 512 macrocells. The M4A5 variant specifically supports 5-V operation, making it suitable for mixed-voltage systems where 5-V inputs are present without overdriving lower voltage components.

Complex Programmable Logic Devices Replacement Considerations

The M4A5-128/64-12YNI is a confirmed slower speed grade alternative within the same family. Verify pinout compatibility before substitution.
