CAT24C256YI-GT3 Working Principle

CAT24C256YI-GT3 utilizes a two-wire serial interface. It is compatible with the I2C-bus protocol defined in the I2C-bus Specification Version 2.1. Power supply to the CAT24C256YI-GT3 can range from 1.7V to 5.5V. Power down circuitry to conserve power is also included.

The CAT24C256YI-GT3 is divided into 256 pages, each containing 64 bytes of data. The CAT24C256YI-GT3 has a flexible addressing system to write/read individual bytes, sequential bytes, and entire pages. The data can also be written or read in multiple bytes. Writing data can be initiated internally or externally, depending on the state of the write enable (WE) pin. Internal erase and write cycles are self-timed and automatically initiate an internal write cycle when the data is received without external instructions. Internal erase cycles are automatically initiated by the internal write cycles.

The CAT24C256YI-GT3 supports the I2C bus protocol for read and write operations. The CAT24C256YI-GT3 is accessed via the serial clock (SCK) and the serial data (SDA) lines. The SCK line is used to initiate and synchronize the data transfer timing while the SDA line is used to transfer data in and out of the CAT24C256YI-GT3.

CAT24C256YI-GT3 also have several features to enhance programming, read operations and erase/write cycles. These features include write protect, hardware write protect control, hardware write protect verify, soft write protect, and second write cycle verification. These features provide additional levels of security to protect the data stored in the device.

Overall, the CAT24C256YI-GT3 is a versatile, reliable and low power serial EEPROM device suitable for many memory applications. It is a great choice for designers to store and protect data in products requiring extended temperatures, small form factor, low power operation, and easy interface to microcontrollers.
