Memory IC Procurement Notes

Verify the specific suffix PF8 against the official Renesas datasheet to confirm the package type and temperature grade match your design requirements. Ensure that the 100-TQFP footprint dimensions align with your PCB layout constraints. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 128K x 36 bit organization is required for wide data paths. Choose this part over asynchronous SRAMs if the system design relies on synchronous clocking for simplified timing closure. Consider the 9 ns access time and 95 MHz limit to ensure it meets the throughput demands of the target application bus speed.
