M4A3-512/192-7FANC

Complex Programmable Logic Devices Overview

The M4A3-512/192-7FANC is a high-performance, E2CMOS Complex Programmable Logic Device (CPLD) from the ispMACH 4A family. It features 512 macrocells and supports up to 192 user I/Os in a 256-ball fine-pitch Ball Grid Array (fpBGA) package. Operating at a nominal 3.3 V supply voltage, this industrial-grade device (-7 speed grade) delivers a maximum propagation delay of 7.5 ns and a maximum operating frequency of 125 MHz. The architecture utilizes a central switch matrix for 100% routability and includes JTAG boundary scan compliance for system integration.

Complex Programmable Logic Devices Feature Summary

• High-density logic with 512 macrocells and up to 192 I/Os
• Industrial temperature range operation (-40°C to +85°C)
• Guaranteed fixed timing via SpeedLocking feature
• JTAG (IEEE 1149.1) compliant for boundary scan testing

Complex Programmable Logic Devices Applications

• Complex digital logic interfacing
• System bus bridging and protocol conversion
• Industrial control systems requiring robust timing

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized Lattice Semiconductor distributors or certified suppliers. Confirm that the fpBGA-256 package matches design footprint requirements. Ensure environmental specifications meet industrial standards if deployed in harsh conditions. Check for lead-free certification if RoHS compliance is mandatory for the target assembly process.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require high pin counts and significant logic density within a single CPLD. The -7 speed grade is suitable for applications needing 125 MHz performance with guaranteed timing. Compare against lower density options like the M4A3-384 if resource utilization permits, or consider higher speed grades if latency constraints are stricter than 7.5 ns.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which offers flexible architectures for rapid logic design. The M4A3-512 variant represents the highest density option in the 3.3-V series, providing extensive programmability. It shares architectural similarities with other M4A3 devices but distinguishes itself through its specific macrocell count and I/O configuration capabilities.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other M4A3-512 variants with different speed grades or package types. Cross-family migration to newer Lattice CPLDs may require schematic and code adjustments due to architectural differences.
