M5LV-256/104-10VI

Complex Programmable Logic Devices Overview

The M5LV-256/104-10VI is a Complex Programmable Logic Device (CPLD) from the Lattice MACH 5 family, utilizing E²CMOS technology. It features 256 macrocells and supports up to 104 user I/O pins within a 144-pin TQFP package. The device operates at a 3.3-V supply voltage with a maximum pin-to-pin delay of 10 ns and a maximum counter frequency of 182 MHz. It includes IEEE 1149.1 compliant in-system programming and boundary scan capabilities.

Complex Programmable Logic Devices Feature Summary

Complex Programmable Logic Devices Procurement Notes

Verify component status as select devices in the MACH 5 family have been discontinued. Confirm availability through authorized distributors or secondary markets. Ensure design compatibility with the 144-pin TQFP footprint and 3.3-V power requirements before procurement.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 256 macrocells and high I/O density in a TQFP package. The -10 speed grade provides a 10 ns delay suitable for PCI-compliant systems. Choose this over the M5-256 variant if a 3.3-V core voltage is required while maintaining 5-V input tolerance.

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 designation indicates a 3.3-V device, distinct from the 5-V M5 series. The family utilizes a hierarchical architecture with block and segment interconnects to ensure 100% routability and pin-out retention across different density options.

Complex Programmable Logic Devices Replacement Considerations

For direct replacements, consider other M5LV-256 variants with different speed grades (e.g., -7VI or -12VI) if timing constraints allow. Pin-compatible alternatives within the same package and I/O count should be verified against the manufacturer's discontinuation notices.
