HN58X24512I
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
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 SCL low period.
Data Validity (SDA data change timing waveform)

SDA
High-to-low and low-to-high change of SDA should be done during SCL low periods.
