AT25SL641-SHE-T

Memory IC Overview

The AT25SL641-SHE-T is a 64Mbit SPI Serial Flash Memory component manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.7V to 2V and supports clock frequencies up to 104 MHz. The device utilizes an 8-UDFN (5x6) package with exposed pad for surface mount installation. It features non-volatile memory technology with a storage capacity organized as 8M x 8 bits. The operational temperature range extends from -40°C to +85°C in ambient conditions.

Memory IC Feature Summary

• Supports Dual I/O and Quad I/O operations via SPI interface
• Includes three security register pages for unique device serialization and locked key storage
• Standard block architecture optimized for code and data storage applications

Memory IC Applications

• Code shadowing from Flash memory into embedded or external RAM for execution
• System-level Electronic Serial Number (ESN) storage
• Unique device serialization and locked key storage

Memory IC Procurement Notes

Verify the specific suffix SHE-T against official Renesas documentation to confirm the exact package type and tape & reel specifications. Ensure compatibility with the 1.7V to 2V operating voltage range required by this component variant. Cross-reference the pinout and command set with standard SPI flash requirements to guarantee system integration integrity.

Memory IC Selection Notes

Select this component for 3V systems requiring low-voltage operation down to 1.7V. Consider the 8-UDFN package dimensions for space-constrained designs. Verify that the application requires Dual or Quad I/O support and benefits from the standard block architecture. Confirm thermal requirements align with the -40°C to +85°C operating range.

Memory IC Part Context

This part belongs to the AT25xF series of SPI flash memories designed for 3V systems. It shares universal pinout and command set compatibility with other members of the family. The architecture is tailored for modern code and data storage needs, offering optimized erase block sizes and enhanced security features for system-level applications.

Memory IC Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other manufacturers' devices without verifying electrical parameters and pinouts.
