Complex Programmable Logic Devices Procurement Notes

Verify component status before integration, as specific suffixes may indicate end-of-life or obsolescence stages. Confirm that the 56-pin CSBGA package dimensions align with the target PCB footprint. Ensure design tools support the ispMACH 4000ZE family for accurate timing analysis and programming.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 64 macrocells and high-speed operation up to 260 MHz. The 1.8 V core voltage makes it suitable for battery-powered applications. Compare against the LC4064ZE-4UMN64C if a UCBGA package is preferred, noting potential differences in pin count and thermal characteristics.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000ZE family, which blends ispLSI 2000 and ispMACH 4A architectures. The family emphasizes low power and high performance, offering global routing pools for predictable timing. It serves as a successor to older CPLD generations, providing density migration capabilities and enhanced I/O flexibility.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same density include other variants of the LC4064ZE series with different packages or speed grades. Verify pin compatibility when substituting with packages such as TQFP or FTBGA, as I/O counts may vary across form factors.
