Pinout

The 24LC02BT-I/SN is an EEPROM (Electrically Erasable Programmable Read-Only Memory) with a 2K (256 x 8) capacity, manufactured by Microchip Technology. It comes in an 8-pin Small Outline Integrated Circuit (SOIC) package. The pin functions are as follows:
1. A0, A1, A2 (Pins 1, 2, 3): These are device address inputs used for multiple device selection in a single bus system.
2. VSS (Pin 4): Ground reference for the power supply.
3. SDA (Pin 5): Serial Data Line used for bi-directional data transfer.
4. SCL (Pin 6): Serial Clock Line used to synchronize data transfer to and from the memory device.
5. WP (Pin 7): Write Protect input; when connected to VCC, it disables all write operations.
6. VCC (Pin 8): Supply voltage input.
The 24LC02BT-I/SN communicates via the I2C bus protocol, which requires only two wires for communication, making it suitable for applications where low pin count and simplicity are desired.
