R1EX24512BSAS0A/R1EX24512BTAS0A
Pin Function
Serial Clock (SCL)
The SCL pin is used to control serial input/output data timing. The SCL input is used to positive edge clock data into
EEPROM device and negative edge clock data out of each device. Maximum clock rate is 1 MHz.
Serial Input/Output Data (SDA)
The SDA pin is bidirectional for serial data transfer. The SDA pin needs to be pulled up by resistor as that pin is open-
drain driven structure. Use proper resistor value for your system by considering V OL , I OL and the SDA pin capacitance.
Except for a start condition and a stop condition which will be discussed later, the SDA transition needs to be completed
during the SCL low period.

Note:
High-to-low and low-to-high change of SDA should be done during the SCL low period.
