Pin # Pin Name Description Notes
1 VDD Power supply
Device power is supplied through the VDD line. Power supply decoupling capacitors
should be placed as close as possible to pin 1 and pin 8 of the device.
2SCL
(1)
1. The control signals SCL and SDA are not tolerant of voltages higher than VDDIO + 0.3 V. If VDDIO is removed, then the control signals SCL
and SDA will clamp any logic signals with their internal ESD protection diodes. The SDA and SCL I
2
C connections are open drain, and
therefore require a pullup resistor to VDDIO.
