Description

The 24LC01BT-I/OT is a 1Kb (kilobit) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Microchip Technology. It operates using the I²C (Inter-Integrated Circuit) serial bus protocol, which requires only two wires—SDA (Serial Data) and SCL (Serial Clock)—for data communication, making it efficient for low-pin-count applications.
This EEPROM is organized as 128 x 8 bits, allowing byte-level read and write operations. It supports a wide operating voltage range from 1.7V to 5.5V, ensuring compatibility with different microcontroller systems. The 24LC01BT-I/OT is known for low power consumption, with active current typically around 1mA and standby current around 1µA, making it suitable for battery-powered devices.
The device is equipped with a write-protect feature to prevent accidental data overwrites, and offers a 100kHz clock frequency for standard mode and up to 400kHz for fast mode operation. It comes in a small SOT-23-5 package, which is ideal for space-constrained applications. The 24LC01BT-I/OT is used in various applications requiring reliable non-volatile memory storage.
