PIN DESCRIPTIONS
NAME
16-QFN
PIN #
TYPE
DESCRIPTION
UART Signals
RX
10
I
UART Channel A Receive Data or IR Receive Data. This pin has an internal
pull-up resistor. Internal pull-up resistor is not disabled during suspend mode.
TX
9
O
UART Channel A Transmit Data or IR Transmit Data.
GPIO0/RI#/RWK#
8
I/O
General purpose I/O or UART Ring-Indicator input (active low) or Remote
Wakeup input. See
“Section 1.5.13, Remote Wakeup” on page 11.
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 device power consumption in the suspend mode.
GPIO1/CD#
7
I/O
General purpose I/O or UART Carrier-Detect input (active low). 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
device power consumption in the suspend mode.
GPIO2/DSR#
6
I/O
General purpose I/O or UART Data-Set-Ready input (active low).
See ”Sec-
tion 1.5.6, Automatic DTR/DSR Hardware Flow Control” on
page 9.
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 device power consumption in the suspend mode.
GPIO3/DTR#
5
I/O
General purpose I/O or UART Data-Terminal-Ready output (active low).
See
”Section 1.5.6, Automatic DTR/DSR Hardware Flow Control” on
page 9.
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 device power consumption in the suspend mode.
GPIO4/CTS#
4
I/O
General purpose I/O or UART Clear-to-Send input (active low).
See ”Sec-
tion 1.5.5, Automatic RTS/CTS Hardware Flow Control” on page 9.
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 device power consumption in the suspend mode.
GPIO5/RTS#/RS485
3
I/O
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 Hard-
ware Flow Control” on page 9 or “Section 1.5.8, Auto RS-485 Half-
Duplex Control” on page 10. 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 device power consumption
in the suspend mode.
USB Interface Signals
USBD+
15
I/O
USB port differential data plus. This pin has a 1.5 K Ohm internal pull-up.
USBD-
14
I/O
USB port differential data minus.
