Overview

The AT25160B-SSHL-T is a 16Kbit industrial-grade serial EEPROM utilizing the SPI bus interface for high-speed data transfers up to 20 MHz. It is organized as 2,048 words of 8 bits each and operates across a wide voltage range of 1.8V to 5.5V, making it compatible with various logic levels. This non-volatile memory is housed in a standard 8-pin SOIC package and is designed for reliable data retention in embedded systems.

Why Choose This Part

The device features a high-speed SPI interface supporting up to 20 MHz clock rates for fast read/write operations. Its wide supply voltage range from 1.8V to 5.5V allows for seamless integration into both legacy 5V systems and modern low-power 1.8V designs without level shifters.

Applications

Microcontroller Configuration Storage
Storing boot parameters, calibration data, and system settings that must persist across power cycles.
Event Logging
Recording error logs, usage statistics, or sensor data history in low-power industrial devices.
User Preference Retention
Saving user-defined profiles and interface settings in consumer electronics and smart home devices.

Getting Started

To interface with this EEPROM, configure your MCU SPI peripheral for Mode 0 or Mode 3. Use the standard SPI instruction set including WREN (Write Enable), WRITE, and READ commands while monitoring the RDY/BUSY bit in the status register during write cycles. Ensure the CS pin is toggled correctly for every instruction frame to reset the internal logic.
