Working Principles

The AT24C164-10SI-2.5 utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. It uses a serial I2C bus for communication with the host microcontroller. The device is organized into multiple memory pages, each consisting of 128 bytes.

To write data, the microcontroller sends a start condition followed by the device's 7-bit address and a write command. The memory address is then transmitted, and the actual data is sent in subsequent bytes. The device acknowledges each byte received.

During a read operation, the microcontroller initiates communication similarly but with a read command. The requested memory address is transmitted, and the device responds by sending the requested data.

Detailed Application Field Plans

The AT24C164-10SI-2.5 finds application in various electronic devices that require non-volatile storage, such as: - Consumer electronics (e.g., TVs, set-top boxes, audio players) - Industrial control systems - Automotive electronics - Medical devices - IoT (Internet of Things) devices

It is commonly used for storing configuration settings, user preferences, calibration data, and small amounts of frequently accessed information.
