Memory IC Procurement Notes

Verify the specific suffix 'B' against official Renesas documentation to confirm package dimensions and tape/reel specifications. Ensure compatibility with system voltage requirements of 2.3V to 3.6V. Confirm that the 85 MHz clock speed aligns with the host controller's SPI capabilities. Check for any recent Product Change Notifications regarding labeling or assembly updates.

Memory IC Selection Notes

Select this component when a 16 Mbit capacity with dual SRAM buffers is required for optimized data throughput. It is suitable for designs needing byte-level write granularity similar to EEPROM but with NOR Flash density. Verify that the 8-SOIC package fits the PCB layout constraints and that the operating temperature range meets environmental specifications.

Memory IC Part Context

This part belongs to the AT45DB161E DataFlash series, designed for system-enhancing code and data storage. It integrates controllable SRAM buffers to reduce processor overhead and simplify software development. The series emphasizes power savings and comprehensive data security options for robust embedded memory applications.

Memory IC Replacement Considerations

AT45DB161E-SSHF2B-T is listed as a similar alternative with identical electrical characteristics but differs in packaging format (Tape & Reel vs. Tube). Verify pinout and command set compatibility before substitution.
