Overview

The AT25SF081B-MAHB-T is an 8Mbit Serial Flash memory device designed for systems where high reliability and fast performance are required. It supports Standard SPI as well as Dual and Quad I/O modes, reaching clock frequencies up to 108 MHz. The device operates from a 2.7V to 3.6V supply and is housed in a compact 8-pad UDFN package measuring 2x3mm.

Why Choose This Part

This NOR flash offers high-speed data transfer with Quad I/O throughput and maintains excellent reliability with a 20-year data retention rating. Its small 2x3mm UDFN footprint and low standby current of approximately 13.3uA make it suitable for power-sensitive portable designs.

Applications

Microcontroller Boot Code
Storing executable code for fast shadow-loading into RAM upon system startup.
Firmware Updates
Providing non-volatile storage for OTA (Over-the-Air) firmware images and rollback versions.
Configuration Logging
Storing calibration data and user settings in space-constrained embedded systems.

Getting Started

Engineers can interface with this memory using standard SPI libraries on any MCU. For development, ensure the SPI controller supports Quad I/O if maximum throughput is required, and refer to the Serial Flash Discoverable Parameters (SFDP) register for automated driver configuration.

Also Consider

W25Q80DVSSIG Winbond Electronics - A widely used alternative 8Mbit SPI flash with similar Quad SPI performance and a standard SOIC-8 footprint.
MX25L8006EM1I-12G Macronix - Offers 8Mbit capacity with lower clock speeds for applications where power consumption is more critical than raw throughput.
