Pin Function

SCL (Serial clock)

The SCL signal is used to control serial input data timing. The SCL is used to latch input data synchronously

at the rising edge and read output data synchronously at the falling edge.

SDA (Serial input / output data)

The SDA pin is bidirectional for serial data transfer. It is an open-drain structure that needs to be pulled up by

resistor.

WP (Write protect)

When the WP input is high, write protection is enabled. When WP input is either low or floating, write

protection is disabled. The read operation is always activated irrespective of the WP pin status.

VDD2 (Power supply for WP pin pull-up)

VDD2 pin is for the pull-up power supply to WP pin. Voltage impression of 0.5 V to VDD +0.5 V is permitted

like other pins about the pin voltage.
