PIN DESCRIPTIONS
Pin Description
NAME
40-QFN
PIN #
TYPE
DESCRIPTION
I2C (SPI) INTERFACE
GPIO0
2
I/O
General purpose I/O pin. If this pin is an input and is unused, it should be con-
nected to VCC or GND. If this pin is an output and is unused, it should be left
unconnected. See IODir register.
GPIO1
5
I/O
General purpose I/O pin. If this pin is an input and is unused, it should be con-
nected to VCC or GND. If this pin is an output and is unused, it should be left
unconnected. See IODir register.
I2C/SPI#
6
I/O
I2C-bus or SPI interface select. I2C-bus interface is selected if this pin is HIGH.
SPI interface is selected if this pin is LOW
GPIO2
8
I/O
General purpose I/O pin. If this pin is an input and is unused, it should be con-
nected to VCC or GND. If this pin is an output and is unused, it should be left
unconnected. See IODir register.
XTAL1
13
I
Crystal or external clock input.
XTAL2
14
O
Crystal or buffered clock output.
GPIO3
16
I/O
General purpose I/O pin. If this pin is an input and is unused, it should be con-
nected to VCC or GND. If this pin is an output and is unused, it should be left
unconnected. See IODir register.
SDA
18
O
I2C-bus data input/output (open-drain). If SPI configuration is selected, then this
pin is undefined and must be connected to VCC.
SCL
23
I
I2C-bus or SPI serial input clock.
When the I2C-bus interface is selected, the serial clock idles HIGH. When the
SPI interface is selected, the serial clock idles LOW.
IRQ#
27
OD
Interrupt output (open-drain, active LOW).
RESET#
28
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.
VCC
35
Pwr
2.97V to 3.63V power supply.
A0
CS#
36
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).
A1
SI
37
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.
SO
40
O
SPI data output pin. If SPI configuration is selected then this pin is a three-state-
able output pin. If I2C-bus configuration is selected, this pin is undefined and
must be left unconnected.
