Memory IC Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics Corporation. Verification of availability is restricted to existing stock or surplus channels only. Procurement requires confirmation of part authenticity and physical condition. Buyers must review end-of-life notices and ensure compliance with RoHS non-compliance status before acquisition.

Memory IC Selection Notes

Engineers should evaluate the 71421SA55 series for legacy system maintenance where specific pinouts are required. Selection depends on verifying compatibility with existing 5V logic levels and 55 ns timing constraints. Designers must account for the discontinuation status when planning long-term production runs or replacement strategies.

Memory IC Part Context

The 71421SA55PF8 belongs to the Renesas 71421SA family of dual-port SRAMs. This series provides high-performance memory solutions for applications requiring concurrent read/write operations from separate ports. The PF8 suffix specifically denotes the 100-pin TQFP surface-mount package configuration.
