Complex Programmable Logic Devices Procurement Notes

Verify the specific package type associated with the CAI suffix against official documentation, as datasheets list fpBGA and caBGA options for this density. Confirm availability status through authorized distributors, as lead times and stock levels vary by region and date.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 128 macrocells and 64 I/Os with industrial temperature support. Ensure the design fits within the 167 MHz frequency limit and 7.5 ns propagation delay constraints. Verify that the required pinout can be accommodated by the available package options for the 1:1 macrocell-to-I/O ratio configuration.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4A CPLD family, which offers densities from 32 to 512 macrocells. The M4A3 series specifically targets 3.3 V operation, while the M4A5 series supports 5 V. The family emphasizes first-time-fit capabilities and pin-out retention across design revisions.

Complex Programmable Logic Devices Replacement Considerations
