M4A3-256/128-10FANI

Complex Programmable Logic Devices Overview

The M4A3-256/128-10FANI is a Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4A family. It features 256 macrocells and supports up to 128 user I/Os. The device operates at a maximum frequency of 167 MHz with a typical propagation delay of 5.5 ns. It utilizes E2CMOS technology for in-system programming via JTAG. The component is housed in a fine-pitch Ball Grid Array (fpBGA) package, designed for high-density applications requiring flexible logic architecture and guaranteed fixed timing performance.

Complex Programmable Logic Devices Feature Summary

• High-performance E2CMOS architecture with 256 macrocells and 128 I/Os
• SpeedLocking feature ensures guaranteed fixed timing independent of design complexity
• Supports 3.3-V operation with JTAG boundary scan compliance
• Flexible routing via central switch matrix and output/input switch matrices

Complex Programmable Logic Devices Applications

• High-speed digital logic interfacing
• System integration in mixed-voltage environments
• Replacement for complex discrete logic circuits

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix '10FANI' against official Lattice documentation to confirm package type and speed grade. Confirm availability status as distribution channels may list end-of-life or limited stock items. Ensure compatibility with existing PCB footprints for the fpBGA package before procurement.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are required with a 5.5 ns speed grade. The '10' suffix indicates a specific speed bin within the commercial range. Verify that the fpBGA package fits the board space constraints. Consider the M4A3-256/128-7 variant if a slower speed grade is acceptable for cost optimization.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A family, which offers densities from 32 to 512 macrocells. The M4A3-256/128 variant provides a balance between logic density and I/O count. The family is known for its first-time-fit capability and pin-out retention during design revisions.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other speed grades of the M4A3-256/128 series, such as M4A3-256/128-7FANI, provided timing requirements allow for slower speeds. Ensure any substitute maintains the same fpBGA package footprint.
