AT25SF041B-SHB-T

Memory IC Overview

The AT25SF041B-SHB-T is a 4 Mbit SPI NOR flash memory IC manufactured by Renesas Electronics Corporation. It operates within a voltage range of 2.7 V to 3.6 V and supports single, dual, and quad SPI interfaces with a maximum clock frequency of 108 MHz. The device features a 512 K x 8 organization and is housed in an 8-SOIC package. It functions reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports Single, Dual, and Quad I/O SPI interface modes for flexible data transfer
• Includes three security register pages for unique device serialization and key storage
• Enables Execute-in-Place (XiP) operation for direct code execution from memory

Memory IC Applications

• Embedded systems requiring shadowed code execution from Flash to RAM
• Consumer electronics utilizing standard block architecture for data storage
• Industrial control applications needing secure device serialization

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing components. Confirm that the 8-SOIC package dimensions match the design footprint requirements. Ensure the operating voltage range aligns with the system power supply specifications. Check for RoHS compliance status relevant to the manufacturing date code.

Memory IC Selection Notes

Select this component for designs requiring a universally compatible pinout and command set within the AT25xF family. It is suitable for applications needing optimized erase block sizes for code and data storage. Consider the 108 MHz speed capability if high-performance sequential or random access is required.

Memory IC Part Context

This part belongs to the AT25SF041B series of SPI NOR flash memories designed for 3V systems. It shares architectural similarities with other members like the AT25SF041B-SSHB-B but differs in packaging and moisture sensitivity handling. The series emphasizes standard features for reliable code and data storage solutions.

Memory IC Replacement Considerations

The AT25SF041B-SSHB-B is a documented alternative offering identical electrical specifications but utilizes tube packaging instead of tape and reel. Verify package compatibility before substitution.
