M5LV-128/74-12VI

Complex Programmable Logic Devices Overview

The M5LV-128/74-12VI is a 3.3-V Complex Programmable Logic Device (CPLD) from the MACH 5 family, featuring 128 macrocells and 74 user I/O pins in a 100-pin TQFP package. It operates at a maximum propagation delay (tPD) of 12 ns and supports a maximum counter frequency (fCNT) of 182 MHz. The device utilizes E2CMOS technology, offering IEEE 1149.1 boundary scan compliance and in-system programmability. It includes features such as individually programmable output slew rates, four power/speed settings per block, and compatibility with mixed supply voltage systems.

Complex Programmable Logic Devices Procurement Notes

Verify component status before procurement, as select devices in the MACH 5 family have been discontinued. Confirm that the -12 speed grade meets specific timing requirements for the target application. Ensure the design environment supports the LatticePRO software for in-system programming via the IEEE 1149.1 Test Access Port.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 3.3-V operation with moderate logic density. The 12 ns speed grade is suitable for PCI Local Bus Specification version 2.1 compliance. Consider the 100-pin TQFP package for space-constrained designs needing 74 I/Os. Verify that the 128 macrocell count adequately covers the logic requirements without excessive unused resources.

Complex Programmable Logic Devices Part Context

This part belongs to the MACH 5 CPLD family, which offers densities from 128 to 512 macrocells. The M5LV prefix indicates 3.3-V operation, distinguishing it from the 5-V M5 series. The /74 suffix specifies the 74 I/O configuration within the 100-pin TQFP package option available for the 128-macrocell density.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult Lattice Semiconductor for current availability or alternative components within the same family if this specific variant is discontinued.
