Complex Programmable Logic Devices Procurement Notes

Verify package type YNI corresponds to the specific pin count and footprint required for your PCB design. Confirm that the 5V supply voltage aligns with your system's power rails. Ensure your programming tool supports the JTAG interface for the ispMACH 4A family.

Complex Programmable Logic Devices Selection Notes

Select this model if your design requires 128 macrocells and 64 I/Os with a 7ns speed grade. Consider the M4A3 variant if your system operates at 3.3V instead of 5V. Check the package options table to ensure the YNI package is available for the 128 macrocell density.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A family, which offers flexible architecture with 32 to 512 macrocells. The family supports both 3.3V and 5V operations, providing designers with options for mixed-voltage systems and various performance grades ranging from 5ns to 14ns delays.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other speed grades of the M4A5-128 series, such as M4A5-128-7YNI or M4A5-128-10YNI, depending on timing requirements. Ensure the package remains compatible.
