Pin Functions
1. A2 (TEST) pin
The slave address can not be assigned in the S-24C16C since addressing function is removed.
The A2 pin should be connected to the GND pin.
2. SDA (Serial data input / output) pin
The SDA pin is used for the bi-directional transmission of serial data. This pin is a signal input pin, and an Nch open-
drain output pin.
In use, generally, connect the SDA line to any other device which has the open-drain or open-collector output with
Wired-OR connection by pulling up to VCC by a resistor (Figure 7 shows the relation with an output load).
3. SCL (Serial clock input) pin
The SCL pin is used for the serial clock input. Since the signals are processed at a rising or falling edge of the SCL
clock, pay attention to the rising and falling time and comply with the specification.
4. WP (Write protect input) pin
The write protect is enabled by connecting the WP pin to VCC. When not using the write protect, connect this pin to
the GND pin or set in open.
