It supports Fast Mode Plus at 1 MHz (above 2.5V) and operates from 1.7V to 5.5V, making it versatile across voltage domains. With over 1 million write cycle endurance, 100-year data retention, and a hardware write-protect pin, it provides reliable nonvolatile storage for consumer, industrial, and automotive applications.","working_principle":"The AT24C02C communicates via the I2C 2-wire protocol (SDA, SCL). The master initiates communication by sending a device address byte (1010+A2A1A0+R\/W), followed by the memory address and data. During a write operation, up to 8 bytes can be written in a single page write cycle, which completes internally within 5 ms. During read operations, data is output sequentially with automatic address incrementing. The WP pin, when tied to VCC, prevents any write operations to the entire memory array, providing hardware data protection.","pin_description":"\n
