Specialized Procurement Notes

Verify the exact suffix against official Renesas documentation, as 'IE' may denote specific environmental or packaging variants not fully detailed in general listings. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy bridge ICs often have complex regulatory histories. Ensure the supplier provides valid traceability documents for this specialized interface component.

Specialized Selection Notes

Select this component when designing VMEbus systems requiring direct connection to a local PCI bus. It is suitable for CPU or peripheral boards functioning as both master and slave. Consider the 313-PBGA package constraints and 5V operation requirements. Verify compatibility with IEEE 1149.1 JTAG standards if boundary scan testing is required for the design.

Specialized Part Context

The CA91C142D belongs to the Universe II family, recognized for high-performance PCI to VME interconnect solutions. This series eases development of VMEbus systems by providing robust bridging capabilities. The device supports advanced PCI processors and peripherals, offering flexible interrupt logic and automatic initialization for VME slave-only applications.

Specialized Replacement Considerations

Direct substitutes include other parts within the CA91C142D family, such as the CA91C142D-33CE or CA91C142D-25EE, depending on temperature range and packaging needs. Verify pinout and register compatibility before substitution.
