Pin Functions

PIN I/O TYPE(1) DESCRIPTION
NAME NO.
SDA 1 I/O Serial data line for I2C, open-drain; requires a pull-up resistor to VDD
GND 2 G Ground
NC 3,4 - These pins may be left floating, or connected to GND
VDD 5 P Supply Voltage
SCL 6 I Serial clock line for I2C, open-drain; requires a pull-up resistor to VDD
DAP DAP - Die Attach Pad. Should be left floating. (On bottom of the device, not shown in the figure)
(1) P=Power, G=Ground, I=Input, O=Output
