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 400
kHz.
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 SCL low period.
Data Validity
(SDA data change timing waveform)
Note:
High-to-low and low-to-high change of SDA should be done during SCL low periods.
Device address
(A0, A1, A2)
Eight devices can be wired for one common data bus line as maximum. Device address pins are used to
distinguish each device and device address pins should be connected to V
CC
or V
SS
. When device address
code provided from SDA pin matches corresponding hard-wired device address pins A0 to A2, that one
device can be activated. As for 4k EEPROM, some device address pins don't need to be fixed since device
address code provided from the SDA pin is used as memory address signal.
