EP
Exposed Paddle. The 32-lead LFCSP_VQ has an exposed paddle that must be left unconnected.
1
RESET
I
Reset Pin. Input pin, active low. An external 1 k pull-up resistor is recommended with this pin.
2
TMS
I
JTAG Test Mode Select. Input pin used for debug and download. An external pull-up resistor
(~100 k) should be added to this pin.
3
P1.0/IRQ1/SIN/T0
I/O
General-Purpose Input and General-Purpose Output P1.0/External Interrupt Request 1/Serial
Input/Timer0 Input. This is a multifunction input/output pin offering four functions.
4
P1.1/SOUT
I/O
General-Purpose Input and General-Purpose Output P1.1/Serial Output. This is a dual function
input/output pin.
5
DAC0
O
DAC Output. Analog output pin.
6
ADC5/EXT_REF2IN
I
Single-Ended or Differential Analog Input 5/External Reference Negative Input. This is a dual
function analog input pin. The ADC5 serves as the analog input for the auxiliary ADC. The
EXT_REF2IN serves as the external reference negative input by ADC for the auxiliary channel.
7
ADC4/EXT_REF2IN+
I
Multifunction Analog Input Pin. This pin can be used for the single-ended or differential Analog
Input 4, which is the analog input for the auxiliary ADC, or it can be used for the external
reference positive input for the auxiliary channel.
8
ADC3
I
Single-Ended or Differential Analog Input 3. Analog input for primary and auxiliary ADCs.
9
ADC2
I
Single-Ended or Differential Analog Input 2. Analog input for primary and auxiliary ADCs.
10
IEXC1
O
Programmable Current Source. Analog output pin.
11
IEXC0
O
Programmable Current Source. Analog output pin.
12
GND_SW
I
Switch to Internal Analog Ground Reference. When this input pin is not used, connect it directly
to the AGND system ground.
13
ADC1
I
Single-Ended or Differential Analog Input 1. Analog input for the primary ADC. Negative differential
input for primary ADC.
14
ADC0
I

17
VREF+
I
External Reference Positive Input for the Primary Channel. Analog input pin.
18
VREF
I
External Reference Negative Input for the Primary Channel. Analog input pin.
19
P0.0/SS/ADC6
I/O
General-Purpose Input and General-Purpose Output P0.0/SPI Slave Select (Active Low)/Input to
Auxiliary ADC6. This is a multifunction input/output pin. Single-ended or differential Analog
Input 6. Analog input for the auxiliary ADC.
20
