M4A3-512/192-14FANI

Complex Programmable Logic Devices Overview

The M4A3-512/192-14FANI is a high-performance Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4A family. It features 512 macrocells and supports up to 192 user I/Os within a 256-ball fine-pitch Ball Grid Array (fpBGA) package. Operating at a nominal 3.3 V supply, this industrial-grade device achieves a maximum propagation delay of 14 ns and a maximum count frequency of 125 MHz. The architecture utilizes E2CMOS technology for in-system programming via JTAG, ensuring 100% pin-out retention and predictable timing through SpeedLocking performance.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix corresponds to the required lead-free packaging and industrial temperature rating. Ensure handling procedures account for moisture sensitivity levels appropriate for BGA packages during reflow soldering processes.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require high macrocell density combined with extensive I/O connectivity in a surface-mount footprint. The -14 speed grade is suitable for applications needing moderate clock speeds up to 125 MHz while maintaining low static power consumption. Compare against lower density variants if fewer macrocells suffice, or consider commercial grades if industrial temperature ranges are not required.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which bridges the gap between simple PLDs and complex FPGAs. The M4A3-512 variant represents the highest density option in the 3.3-V series, offering significant logic capacity. Its design emphasizes ease of use with full pin-out retention across design revisions, simplifying the upgrade path from smaller CPLDs without board redesign.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package may include other speed grades of the M4A3-512 series, such as the -7 or -10 variants, provided timing requirements allow for faster propagation delays. Cross-family migration to newer Lattice architectures requires verification of software tool compatibility and architectural differences.
