The descriptions of the pins are listed in
TABLE 3-1:
3.1
The SDA is a bidirectional input/output pin, used to
serially transmit data to and from the host controller.
This pin requires a pull-up resistor to output data.
3.2
The SCLK is a clock input pin. All communication and
timing is relative to the signal on this pin. The clock is
generated by the host controller on the bus.
3.3
The V
specified in the DC electrical specification table, is
applied on this pin.
3.4
The GND pin is the system ground pin.

The MCP9800/1/2/3’s ALERT pin is an open-drain
output pin. The device outputs an alert signal when the
ambient

These pins are device or slave address input pins and
are available only with the MCP9801/03. The device
addresses for the MCP9800/02 are factory-set.
The address pins are the Least Significant bits (LSb) of
the device address bits. The Most Significant bits
(MSb) (A6, A5, A4, A3) are factory-set to <1001>. This
is illustrated in
