I
Reset (active LOW) - A longer than 40 ns LOW
pulse on this pin will reset the internal registers and
all outputs. The UART transmitter output will be
idle and the receiver input will be ignored.

Auto CTS Hardware Flow Control or as a general
purpose input.

I
I2C-bus device address select A0 or SPI chip
select. If I2C-bus configuration is selected, this pin
along with the A1 pin allows user to change the
device’s base address. If SPI configuration is
selected, this pin is the SPI chip select pin
(Schmitt-trigger, active LOW).

I
I2C-bus device address select A1 or SPI data input
pin. If I2C-bus onfiguration is selected, this pin
along with A0 pin allows user to change the
device’s base address. If SPI configuration is
selected, this pin is the SPI data input pin.

O
SPI data output pin. If SPI configuration is
selected then this pin is a three-stateable output
pin. If I2C-bus configuration is selected, this pin is
undefined and must be left unconnected.

PAD
-
Pwr The center pad on the backside of the QFN pack-
ages is metallic and is not electrically connected to
anything inside the device. It must be soldered on
to the PCB and may be optionally connected to
GND on the PCB. The thermal pad size on the
PCB should be the approximate size of this center
pad and should be solder mask defined. The sol-
der mask opening should be at least 0.0025"
inwards from the edge of the PCB thermal pad.
NC
-
No Connection.
