24LC04BT-I/OT - EEPROM Memory IC | 4Kbit, I2C Interface, 400kHz | SOT-23-5 Package

The 24LC04BT-I/OT from Microchip Technology is a compact, low-power 4Kbit (512x8-bit) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) featuring an I2C-compatible (2-wire) interface. Designed for applications that require reliable non-volatile data storage, this EEPROM operates at clock speeds up to 400kHz and provides exceptional endurance, low power consumption, and fast write capability. With its page write buffer, hardware write protection, and robust ESD protection, the 24LC04BT-I/OT ensures long-term data reliability in both industrial and consumer systems.
