Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and humidity sensitivity handling requirements prior to assembly. Check for specific revision markings on the device surface to ensure compatibility with existing design files.

Complex Programmable Logic Devices Selection Notes

Select this model when 96 macrocells and 48 I/O pins are required within a 3.3 V environment. Ensure the design fits within the 10 ns propagation delay constraint. Consider the TQFP-100 package availability if space constraints allow. Verify that the 167 MHz frequency meets the system clock requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4A CPLD family, which offers densities ranging from 32 to 512 macrocells. The M4A3 series specifically targets 3.3 V applications, providing flexibility for modern digital logic designs while maintaining backward compatibility with older 5 V systems through input tolerance features.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other speed grades of the M4A3-96 series, such as M4A3-96/48-7VNC or M4A3-96/48-5VNC, provided timing constraints allow. Cross-family replacements require careful verification of pinout compatibility and logic density.
