Working Principles

The AT25160BN-SH-B is a Serial EEPROM that utilizes the SPI interface to communicate with a microcontroller or other digital systems. It stores and retrieves digital information by using electrical charges to represent data bits. The device can be accessed by enabling the Chip Select (/CS) pin and transferring data through the Serial Clock (SCK), Serial Data Input (SI), and Serial Data Output (SO) pins. Write protection can be enabled using the Write Protect (/WP) pin, and serial communication can be paused using the Hold (/HOLD) pin.

Detailed Application Field Plans

The AT25160BN-SH-B is commonly used in various electronic systems that require non-volatile memory storage. Some of its application fields include:

1. Consumer Electronics: Used in smart TVs, set-top boxes, and audio systems for storing configuration settings and user preferences.
2. Automotive: Employed in car infotainment systems, instrument clusters, and engine control units for data logging and firmware storage.
3. Industrial Automation: Utilized in programmable logic controllers (PLCs), motor drives, and industrial sensors for parameter storage and system configuration.
4. Medical Devices: Integrated into medical equipment such as patient monitors, infusion pumps, and diagnostic devices for storing patient data and device settings.
