Pin Functions
SCL (serial clock input) pin
SDA (serial data input/output) pin
WP (write protect) pin
The SCL pin is a serial clock input pin that processes signals at the rising and falling edges of SCL clock signals.
The SDA pin is used to transfer serial data to the input/output, and it consists of a signal input pin and n-channel
transistor open drain output pin.
Like the SCL pin, the SDA pin must be pulled up by a resistor to the V DD level and wired-ORed with an open drain
(or open collector) output device for use.
When the WP pin is high, write protection is enabled, and writing into the 64k bit memory areas is prohibited. When
the pin is low, writing is possible to all memory areas. Read operations can be performed regardless of the WP pin
status.
