The 24LC04BT-I/OT is a 4K bit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Microchip. It uses the I2C interface and has a storage capacity of 32K bits (4K bytes). The device can operate from a supply voltage of 1.5V to 5V, with a maximum speed of 400 kHz. It features low power consumption and is suitable for low power applications. The memory array is organized into 256-bytes (128) words of 8-bit each. The device support hardware write protection, so that data can be write-protected with two bits, individually or both. The device is also equipped with an emergency write protection feature that prevents accidental overwriting or erasing of data.
