CA91C142D-33CEV

Specialized Overview

The CA91C142D-33CEV is a PCI to VME bridge IC from the Universe IID series, manufactured by Renesas Electronics. It provides high-performance interconnect between PCI and VME64 buses, supporting 32-bit or 64-bit data widths at a maximum clock frequency of 33 MHz. The device operates on a 5V supply voltage with an operating temperature range of -40°C to +85°C. It features a decoupled architecture with independent FIFOs for inbound, outbound, and DMA traffic to maximize throughput. The component is housed in a 313-PBGA package (35x35 mm) and supports IEEE 1149.1 JTAG for testing.

Specialized Feature Summary

• Zero wait state implementation for write transactions to enhance bus utilization

• Medical market peripherals

Specialized Procurement Notes

Verify the specific suffix 'CEV' against official Renesas documentation to confirm it denotes the commercial extended temperature variant (-40°C to +85°C). Ensure compatibility with VME64 standards and check for any lead-free or RoHS compliance certifications required for the target application environment before finalizing procurement.

Specialized Selection Notes

Select this component when a high-performance PCI to VME bridge is required for systems needing zero wait state writes and independent FIFO buffering. It is suitable for applications requiring both master and slave functionality on the VMEbus. Consider the 313-PBGA package size and 5V power requirements during board layout and power design phases.
