Overview

The AT25XE081D-MAHN-T is an 8Mbit SPI NOR Flash memory device designed for low-power applications operating between 1.65V and 3.6V. It features a Quad I/O interface supporting clock frequencies up to 104 MHz and includes specialized features like Ultra Deep Power Down mode and a 128-byte unique identifier.

Why Choose This Part

This device offers exceptional power efficiency with a 7uA shutdown current and an Ultra Deep Power Down mode. The flexible erase architecture and Read-Modify-Write command simplify data management by allowing smaller portions of memory to be updated without external buffering.

Applications

IoT Edge Nodes
Ideal for battery-powered sensors requiring low standby current and fast wake-up times to store local sensor data or firmware.
Wearable Technology
Utilizes the compact 2x3mm UDFN package for space-constrained health trackers and smartwatches.
Secure Boot Storage
Provides OTP security registers and a unique factory ID to support secure boot processes and device authentication.
Firmware Over-the-Air (FOTA) Updates
Supports read-modify-write and erase/program suspend functions to handle background updates while maintaining system responsiveness.

Getting Started

Interface this memory with any MCU using standard SPI or Quad SPI protocols; the device supports JEDEC SFDP for automated parameter discovery. For development, ensure your SPI driver accounts for the 4ms word write cycle and utilize the status register to monitor the active status interrupt for efficient write operations.
