AT45DB081E-SSHN-T
Overview
The AT45DB081E-SSHN-T is an 8 Mbit DataFlash SPI NOR memory device designed for data-intensive applications. Unlike standard NOR flash, it features a flexible SRAM buffer system that allows for page reprogramming without requiring an external sector erase, simplifying firmware overhead for logging and buffering. It operates over a wide voltage range of 1.7V to 3.6V, making it suitable for low-power battery-operated systems.
Why Choose This Part
The DataFlash architecture provides a unique advantage by allowing byte-level writes through its dual 264-byte SRAM buffers, which significantly reduces the software complexity of wear leveling. It features an ultra-low-power mode with a shutdown current of 0.4 uA and supports high-speed SPI clock frequencies up to 85 MHz for rapid data retrieval.
Applications
Key Specifications
Getting Started
To begin development, interface the device via a standard 4-wire SPI bus and utilize the manufacturer's provided C-based drivers for DataFlash commands. For prototyping, use an 8-pin SOIC breakout board or a Microchip Curiosity Nano board to verify the 1.7V to 3.6V operation and command set compatibility.
