Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'B' against current manufacturer documentation, as the 'V' series is more prevalent in recent public listings. Confirm the package type matches the TN176 designation (TQFP-176). Ensure the 'I' suffix corresponds to the required industrial temperature range specifications for your application environment.

Complex Programmable Logic Devices Selection Notes

Select this component when 512 macrocells are sufficient for the design complexity. The 10ns speed grade offers a balance between performance and power consumption. Consider the 176-pin TQFP footprint for PCB layout constraints. Verify that the I/O count requirements do not exceed the 128 available pins on this specific package.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000B family, which succeeded earlier CPLD generations. It provides non-volatile configuration storage, eliminating the need for external configuration memory. The family is designed for applications needing moderate logic density with low power consumption and high reliability.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may include other parts within the LC4xxx series with compatible speed grades and package types. Verify electrical parameters such as VCCIO requirements and drive strength before substituting.
