Complex Programmable Logic Devices Part Context

This component is part of the ispMACH 4000V/B/C/Z family, which blends ispLSI 2000 and ispMACH 4A architectures. The 'Z' suffix indicates support for the 1.8V core voltage variant, offering lower power consumption compared to the 3.3V or 2.5V variants. The family utilizes Global Routing Pool and Output Routing Pool technology to ensure timing predictability and pin-out retention.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same density and package must be sought from the ispMACH 4000Z series. Verify that alternative parts support the required 1.8V core voltage and 5V tolerant I/O specifications. Note that older variants like the LC4064C may differ in supply voltage requirements and power characteristics.
