Organized as 32K x 8 bits, it supports the I2C Fast-mode Plus protocol at up to 1MHz clock speed for rapid data access. The device features 64-byte page write capability for efficient storage operations, with a 5ms write cycle time. An additional 256-byte Identification Page can be used to store a unique serial number or application-specific data, with permanent write-lock capability for secure storage. The EEPROM offers exceptional endurance of 4 million write cycles and 50-year data retention.","working_principle":"The M24256-BRMN6TP operates using a standard I2C serial interface protocol. (1) The I2C interface receives device address, word address, and data via the SDA line synchronized to the SCL clock. The 7-bit device address consists of a 4-bit preset code (1010) and three programmable address bits (E0-E2), allowing up to 8 devices on the same I2C bus. (2) The memory array is organized as 512 pages of 64 bytes each, supporting random read, sequential read, byte write, and page write operations. During page write, up to 64 bytes can be written in a single write cycle, with the internal address counter incrementing within the page boundary. (3) The write protection (WP) pin controls whether the upper quadrant of the memory array is write-protected, preventing accidental data corruption. The Identification Page is accessed through a separate I2C address and can be permanently locked.","pin_description":"
