AT25FF041A-SHN-B

Memory IC Overview

The AT25FF041A-SHN-B is a 4 Mbit SPI NOR flash memory device manufactured by Renesas Electronics. It operates within a wide supply voltage range of 1.65 V to 3.6 V and supports clock frequencies up to 133 MHz. The component features a 512 K x 8 organization and is housed in an SOIC-8 package. It is designed for single, dual, and quad SPI interface modes, ensuring compatibility with standard embedded systems.

Memory IC Feature Summary

• Supports Single, Dual, and Quad SPI interface modes for flexible data transfer options
• Operates across a wide voltage range from 1.65 V to 3.6 V
• Includes three security register pages for unique device serialization and key storage

Memory IC Applications

• Code execution from flash (XiP) in embedded systems
• Data storage for IoT devices
• Storage for system-level electronic serial numbers (ESN)

Memory IC Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package dimensions and tape/reel specifications. Ensure the selected variant matches the required operating temperature range and interface mode for your design.

Memory IC Selection Notes

Select this component when a low-voltage operation down to 1.65 V is required alongside high-speed access up to 133 MHz. Consider the SOIC-8 footprint and the need for security features like ESN storage in your application architecture.

Memory IC Part Context

This part belongs to the AT25FF series of SPI NOR flash memories. It shares architectural similarities with other members like the AT25FF161A but offers a smaller 4 Mbit density. The series is optimized for code and data storage in consumer and industrial applications.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades within the AT25FF family or cross-reference with similar density parts from other manufacturers if availability is constrained.
