Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm availability status as distribution data may vary. Ensure design tools support the ispMACH 4A family for proper compilation and programming.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring 32 macrocells with 5V operation. The -7 speed grade provides a 7.5 ns propagation delay suitable for moderate-speed applications. Consider the PLCC-44 package constraints during PCB layout. Verify that the design fits within the product term limits for the SpeedLocking feature if fixed timing is required.

Complex Programmable Logic Devices Part Context

This part is part of the ispMACH 4A CPLD family, which offers densities from 32 to 512 macrocells. The M4A5 series specifically denotes 5V operation, while the M4A3 series is for 3.3V. The 32/32 designation indicates a 1:1 macrocell-to-I/O ratio.

Complex Programmable Logic Devices Replacement Considerations

Other devices in the M4A5-32 family with different speed grades (e.g., -5, -55) or packages (e.g., TQFP-44) are pin-compatible. Verify that the replacement meets the specific timing requirements of the application.
