Overview

The AT25XE081D-SHN-T is an 8Mbit SPI-based NOR Flash memory device designed for high-performance data storage and code execution. It supports Quad I/O operations at clock frequencies up to 104 MHz, providing high throughput for embedded applications while maintaining a wide supply voltage range from 1.65V to 3.6V. This component is optimized for power-sensitive designs, featuring an Ultra-Deep Power-Down mode that reduces current consumption to approximately 7uA.

Why Choose This Part

The device offers exceptional power management flexibility with its Ultra-Deep Power-Down mode and a low standby current of 30uA. Its high-speed 104 MHz Quad I/O capability ensures fast data retrieval, and the wide operating voltage allows it to interface directly with both 1.8V and 3.3V logic families without level shifters.

Applications

Firmware Storage
Storing bootloaders and application code for microcontrollers that lack sufficient internal flash.
Data Logging
Recording sensor data or event logs in battery-powered IoT devices where low-power sleep modes are critical.
User Interface Assets
Storing small graphic icons, fonts, and localized text strings for embedded display systems.
Configuration Management
Storing network credentials and device settings that must persist across power cycles.

Getting Started

To interface with this memory, configure your microcontroller's SPI peripheral for Mode 0 or Mode 3. Engineers can use standard SPI flash libraries, but will need to implement specific instruction codes for the Ultra-Deep Power-Down and Quad I/O features as defined in the Renesas datasheet. Hardware verification can be performed using any logic analyzer capable of decoding SPI or Quad SPI traffic at 104 MHz.
