The device operates from 2.5V to 5.5V with low-power CMOS technology, consuming only 1mA read current and 1uA standby current. It supports I2C fast mode up to 400kHz with Schmitt trigger inputs for robust noise immunity. The 8-byte page write buffer allows up to 8 bytes to be written in a single operation with 5ms maximum write cycle time. Hardware write protection via the WP pin protects the entire memory array from unintended writes. The device is available in an 8-pin SOIC package for the industrial temperature range of -40\u00b0C to +85\u00b0C.","working_principle":"The 24LC02BT-I\/SN communicates via a standard I2C 2-wire bus (SDA and SCL). The master initiates communication with a START condition followed by the device address byte (1010+A2A1A0+R\/W). For write operations, the master sends the byte address and up to 8 bytes of data; the device then performs a self-timed internal write cycle lasting up to 5ms. For read operations, the master sends the address then issues a repeated START with the read bit set. The device outputs data sequentially with the master acknowledging each byte. Schmitt trigger inputs on SCL and SDA provide noise immunity, while output slope control minimizes ground bounce during data transmission.","pin_description":"
