Procurement Notes

Verify current availability status with authorized distributors, as this component may be subject to limited supply or end-of-life conditions. Confirm RoHS compliance details and specific package variants before ordering. Cross-reference the manufacturer part number with official Renesas documentation to ensure compatibility with existing system designs and regulatory requirements.

Selection Notes

Select this component when a dedicated TSI solution is required for 3.3V digital environments. The 256 x 256 capacity defines the maximum channel count. Ensure the application matches the digital bus switch specifications rather than general-purpose memory or logic families. Validate interface timing against system clock requirements.
