24LC08BT-I-OT – 8Kbit I2C EEPROM Memory IC | 400kHz SOT23-5 Package
The 24LC08BT-I-OT from Microchip Technology Inc. is a high-performance 8-Kbit (1024×8) serial EEPROM designed for reliable non-volatile data storage in compact, low-power applications. This device operates through a Two-Wire (I2C-compatible) serial interface and is organized as four blocks of 256×8-bit memory. With support for 100 kHz, 400 kHz, and 1 MHz communication speeds, it ensures flexible and fast data access for embedded systems. Operating at a supply voltage of 2.5 V to 5.5 V, this EEPROM offers low power consumption, with only 1 A standby current and 1 mA read current, making it ideal for battery-powered and portable devices. The 16-byte page write buffer, hardware write-protect, and self-timed erase/write cycle deliver reliable performance, while the SOT23-5 package provides space-saving integration for compact PCBs.
