Overview

The AT25SF041B-SSHB-T is a 4Mbit Serial-interface Flash memory device designed for a wide variety of high-volume consumer and industrial applications. It supports standard SPI as well as Dual and Quad I/O operations at clock frequencies up to 108 MHz, providing high-performance data throughput for code shadowing and data storage.

Why Choose This Part

This device offers a flexible erase architecture with support for uniform 4KB, 32KB, and 64KB blocks, allowing for efficient memory management. It features a wide operating voltage range of 2.7V to 3.6V and provides hardware-controlled lockout and software-based block protection for data security.

Applications

Firmware Storage
Ideal for storing boot code and application firmware in small-form-factor embedded systems.
Code Shadowing
Fast 108 MHz clock speeds enable efficient execution of code from RAM by quickly copying data from the Flash memory.
Data Logging
Useful for recording system parameters or sensor data across 100,000 program/erase cycles.
IoT Edge Devices
Low power consumption in deep power-down mode (1.2uA typical) makes it suitable for battery-operated connected devices.

Getting Started

Development can begin using any MCU with a standard SPI or Quad SPI peripheral. For rapid prototyping, use a standard SOIC-8 to DIP adapter or an SOP-8 test clip to interface with common development platforms like an STM32 Nucleo or Arduino. Ensure the SPI clock frequency and mode (0 or 3) are correctly configured in your driver to match the device specifications.
