Overview

The AT25XE041B-MAHN-T is a 4Mbit Serial Flash memory device designed for low-power applications requiring frequent data logging or firmware storage. It features a wide operating voltage range from 1.65V to 3.6V and supports clock frequencies up to 85 MHz via SPI or Dual-I/O interfaces. The 8-UDFN package provides a compact 2mm x 3mm footprint suitable for space-constrained designs.

Why Choose This Part

This device excels in power management with typical active read currents of 3.5 mA and a dedicated Ultra Deep Power Down mode. It includes advanced features such as hardware-controlled locking, sequential program mode for faster data writes, and an OTP security register for unique device identification.

Applications

Wearable Device Data Logging
Ideal for storing sensor logs in fitness trackers or smartwatches due to its ultra-low power consumption modes.
Firmware Storage
Reliable storage for boot code and application firmware in IoT endpoints and small consumer electronics.
Battery-Powered Remote Sensors
The Ultra Deep Power Down mode minimizes energy draw between active transmission cycles in remote monitoring nodes.

Getting Started

To interface with this memory, configure your MCU SPI master for Mode 0 or Mode 3 operation. Implementation should leverage the JEDEC standard ID read command to verify device presence before executing program or erase operations. Developers can use standard SPI libraries available for most toolchains to manage the 512K x 8 memory organization.
