Overview

The AT25FF041A-SSHN-T is a 4 Mbit serial NOR flash memory designed for high-speed data storage and retrieval via Single, Dual, or Quad SPI interfaces. It features a wide operating voltage range from 1.65V to 3.6V, making it compatible with both battery-powered and standard industrial power rails. With a maximum clock frequency of 104 MHz and low power consumption, it is well-suited for code shadowing and data logging applications.

Why Choose This Part

This device offers high throughput with Quad SPI performance and a fast 104 MHz clock. Its ultra-deep power-down mode and low standby current of 30 uA minimize energy consumption in battery-constrained designs. The wide voltage support (1.65V to 3.6V) eliminates the need for level shifters when interfacing with various MCU families.

Applications

Code Shadowing
Storing executable code for high-speed transfer to internal MCU RAM upon power-up.
Data Logging
Recording sensor data or event logs in systems requiring reliable non-volatile storage.
Firmware Updates
Acting as a temporary storage bank for Over-the-Air (OTA) firmware images before application.
Parameter Storage
Retaining user settings, calibration data, and system configuration profiles.

Getting Started

Integration is straightforward using standard SPI or QSPI drivers available in most MCU peripheral libraries. Engineers should verify the JEDEC ID (9Fh) to ensure software compatibility during the initialization sequence. For prototyping, the 8-pin SOIC package is compatible with standard TSSOP/SOIC breakout boards for breadboard use.

Also Consider

S25FL064L Infineon/Cypress - Consider this if your design requires higher memory density in a similar SPI footprint.
