EEPROM (commonly known as I2C bus protocol), a wide range of applications, such as: common baseband chips, logic chips, display interface, camera interface, fingerprint interface, photosensitive interface , vibrator interface and more. Manufacturers often use the I2C bus protocol to match and communicate. If the data does not match, the function will not work properly. The I2C interface defines the communication mode as follows: VCC, SDA, SCL, and GND can be used by reading and writing the original accessory data and writing it to a new accessory. All WL chip test stands support I2C protocol communication, which can read, save, write, erase, verify, repair and other functions.
