Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm exact voltage and temperature ratings. Confirm current availability status as manufacturing lifecycles may have changed. Ensure compatibility with existing PCB footprints and soldering profiles for the CABGA package type before integration into production lines.

Memory IC Selection Notes

Select this component when dual-port functionality with synchronous operation is required for complex data handling tasks. Consider the 36-bit word width for applications needing wide data buses without external multiplexing. Evaluate power consumption requirements against the specified operating voltage range to ensure system stability under varying load conditions.
