The 24LC02BT-I/OT is a 2Kbit I²C non-volatile EEPROM manufactured by Microchip, organized as 256×8-bit memory array in a compact SOT-23-5 package. Built with low-power CMOS technology, it supports 100kHz and 400kHz standard I²C communication with Schmitt trigger noise suppression. It features 8-byte page write operation, million-cycle endurance and long-term data retention, widely used for storing device configuration, calibration data and system information in embedded systems.

Memory Capacity: 2Kbit / 256Byte Interface: Standard I²C, up to 400kHz Supply Voltage: 2.5V～5.5V (minimum 1.7V) Package: SOT-23-5 Operating Temperature: -40℃～+85℃ industrial grade Write/Erase Endurance: ≥1,000,000 cycles per address Data Retention: 200 years at 25℃ Page Size: 8Byte, typical page write time 3ms Power Consumption: 1μA standby current, 1mA operating current Protection: WP pin hardware global write protection

Ultra-small package saves PCB space, suitable for portable devices and miniature sensor modules Wide voltage compatibility supports 3.3V and 5V systems without level shifting Ultra-low standby power consumption, ideal for battery-powered and low-power IoT terminals Hardware write protection prevents accidental erasure and abnormal data modification Schmitt trigger inputs enhance noise immunity for stable operation in industrial EMI environments
