PIN DESCRIPTIONS
Pin Description
NAME
48-QFN
PIN #
TYPE
DESCRIPTION
UART Channel A Signals
RXA
31
I
UART Channel A Receive Data or IR Receive Data. This pin has an inter-
nal pull-up resistor. Internal pull-up resistor is not disabled during suspend
mode.
TXA
30
O
UART Channel A Transmit Data or IR Transmit Data.
GPIOA0/RIA#/
RWKA#
21
I/O
UART Channel A general purpose I/O or UART Ring-Indicator input
(active low) or Remote Wakeup Input (
See ”Section 1.5.12, USB Sus-
pend” on page 14.). This pin has an internal pull-up resistor which is
disabled during suspend mode. If using this GPIO as an input, an external
pull-up resistor is required to minimize the power consumption in the sus-
pend mode.
GPIOA1/CDA#
20
I/O
UART Channel A general purpose I/O or UART Carrier-Detect input
(active low). This pin has an internal pull-up resistor which is disabled dur-
ing suspend mode. If using this GPIO as an input, an external pull-up
resistor is required to minimize the power consumption in the suspend
mode.
GPIOA2/DSRA#
17
I/O
UART Channel A general purpose I/O or UART Data-Set-Ready input
(active low).
See ”Section 1.5.6, Automatic DTR/DSR Hardware
Flow Control” on page 13. This pin has an internal pull-up resistor
which is disabled during suspend mode. If using this GPIO as an input, an
external pull-up resistor is required to minimize the power consumption in
the suspend mode.
GPIOA3/DTRA#
16
I/O
UART Channel A general purpose I/O or UART Data-Terminal-Ready out-
put (active low).
See ”Section 1.5.6, Automatic DTR/DSR Hard-
ware Flow Control” on page 13. This pin has an internal pull-up
resistor which is disabled during suspend mode. If using this GPIO as an
input, an external pull-up resistor is required to minimize the power con-
sumption in the suspend mode.
GPIOA4/CTSA#
7
I/O
UART Channel A general purpose I/O or UART Clear-to-Send input
(active low).
See ”Section 1.5.5, Automatic RTS/CTS Hardware
Flow Control” on page 13. This pin has an internal pull-up resistor
which is disabled during suspend mode. If using this GPIO as an input, an
external pull-up resistor is required to minimize the power consumption in
the suspend mode.
GPIOA5/RTSA#/
RS485A
6
I/O
UART Channel A general purpose I/O or UART Request-to-Send output
(active low) or auto RS-485 half-duplex control.
See ”Section 1.5.5,
Automatic RTS/CTS Hardware Flow Control” on page 13. This
pin has an internal pull-up resistor which is disabled during suspend mode.
If using this GPIO as an input, an external pull-up resistor is required to
minimize the power consumption in the suspend mode.
UART Channel B Signals
RXB
9
I
UART Channel B Receive Data or IR Receive Data. This pin has an inter-
nal pull-up resistor. Internal pull-up resistor is not disabled during suspend
mode.
