Overview

The AT25FF161A-SSHN-T is a 16Mbit Serial-interface Flash memory device designed for a wide range of applications. It supports standard SPI as well as Dual and Quad I/O operations with a maximum clock frequency of 133 MHz. Operating over a wide voltage range of 1.65V to 3.6V, it is optimized for systems requiring high-speed data transfer and low power consumption.

Why Choose This Part

This device features Ultra-Deep Power-Down modes and a standby current of only 30uA, making it ideal for battery-operated systems. Its support for Quad I/O at 133 MHz enables high throughput for fast boot times and efficient data handling. The wide 1.65V to 3.6V supply range ensures compatibility with both legacy 3.3V systems and modern low-voltage chipsets.

Applications

Firmware Storage
Storing boot code and execution-in-place (XiP) application code for microcontrollers and SoCs.
Data Logging
Recording sensor data or event logs in industrial and consumer devices where non-volatile storage is required.
IoT End Nodes
Serving as local storage for wireless modules and smart home devices that operate on battery power.
Wearable Electronics
Providing compact memory storage for fitness trackers and smartwatches utilizing its small 8-SOIC footprint.

Getting Started

Engineers can interface this memory with any MCU supporting SPI or Quad SPI protocols using standard serial flash commands. For development, ensure the host controller's logic levels match the 1.65V to 3.6V supply range and use a SOIC-8 breakout board or socket for prototyping. Proper PCB layout with a decoupling capacitor near the VCC pin is recommended to maintain signal integrity at high clock speeds.
