M4A3-384/192-65FAC

Complex Programmable Logic Devices Overview

The M4A3-384/192-65FAC is a high-performance Complex Programmable Logic Device (CPLD) from the Lattice ispMACH 4A family. It features 384 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 device achieves a maximum propagation delay of 6.5 ns and a maximum operating frequency of 154 MHz. The architecture utilizes E2CMOS technology for in-system programming via JTAG.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required speed grade (-65) and package type (FAC). Ensure compliance with relevant RoHS directives if lead-free packaging is required for the assembly process.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require 384 macrocells with a 1:1 macrocell-to-I/O ratio. The -65 speed grade provides a 6.5 ns delay suitable for applications needing 154 MHz operation. Verify that the 256-ball fpBGA package fits the board space constraints and thermal requirements.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which offers flexible architecture with central switch matrices for 100% routability. The M4A3 series specifically targets 3.3 V applications while maintaining compatibility with 5 V systems through input tolerance features.

Complex Programmable Logic Devices Replacement Considerations

Check for other speed grades within the M4A3-384 series, such as -7 or -10, if lower performance is acceptable. Consider the M4A3-512 variant if additional macrocells are needed.
