Organized as 128K x 8 bits, the device supports high-speed I2C communication up to 1MHz with 256-byte page write capability for efficient data updates. Hardware write protection via the WP pin safeguards the entire memory array against inadvertent writes. The AT24CM01 is available in a standard 8-SOIC package and is suitable for industrial, consumer, and automotive applications where dependable data storage is essential.","working_principle":"The AT24CM01-SSHD-T communicates via the I2C two-wire serial protocol. 1) I2C Interface Subsystem: The SDA (data) and SCL (clock) pins support standard (100kHz), fast (400kHz), and high-speed (1MHz) modes. Device addressing uses a 7-bit address with two configurable address pins allowing up to four devices on a single bus. 2) Memory Array Subsystem: The 1Mb EEPROM array is organized as 128K x 8 bits with 256-byte page boundaries for efficient write operations. 3) Write Protection Subsystem: The WP pin provides hardware data protection for the entire array when driven high; a status register provides software write protection. 4) Write Cycle Subsystem: Upon receiving a write command, the device executes a self-timed internal programming cycle completing within 5ms, during which the inputs are disabled and acknowledge polling can be used to detect completion.","pin_description":"
