Overview

The AT45DB161E-SHF-B is a 16-Mbit DataFlash NOR memory device designed for high-performance sequential data access. It features a unique architecture with two internal buffers, allowing for continuous data streaming and simultaneous read/write operations. Operating between 2.3V and 3.6V, it is optimized for systems requiring non-volatile storage with fine-grained page management.

Why Choose This Part

The device offers an Ultra-Deep Power-Down mode with a typical current consumption of 0.4 uA, making it ideal for battery-operated devices. Its dual-buffer architecture enables programmers to write to one buffer while the other is being programmed into the main memory, significantly reducing system overhead.

Applications

System Boot Code
Storing executable firmware for microcontrollers that require reliable non-volatile storage during the power-up sequence.
Data Logging
Capturing sensor readings or event logs in industrial equipment using its 528-byte page size for efficient data organization.
Voice Storage
Recording and playing back audio clips in consumer electronics thanks to its high-speed sequential read capabilities.

Getting Started

To interface with this part, use a standard SPI bus (Mode 0 or 3). Engineers can utilize existing DataFlash drivers available for common MCU ecosystems like STM32 or AVR, and hardware prototyping can be done using the AT45DB161E-SHF-T variant on an SOIC-8 breakout board.
