Description
Reset Pin. Input pin, active low. An external 1 kΩ pull-up resistor is recommended with this pin.
JTAG Test Mode Select. Input pin used for debug and download. An external pull-up resistor
(~100 kΩ) should be added to this pin.
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.
General-Purpose Input and General-Purpose Output P1.1/Serial Output. This is a dual function
input/output pin.
DAC Output. Analog output pin.
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.
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.
Single-Ended or Differential Analog Input 3. Analog input for primary and auxiliary ADCs.
Single-Ended or Differential Analog Input 2. Analog input for primary and auxiliary ADCs.
Programmable Current Source. Analog output pin.
Programmable Current Source. Analog output pin.
Switch to Internal Analog Ground Reference. When this input pin is not used, connect it directly
to the AGND system ground.
Single-Ended or Differential Analog Input 1. Analog input for the primary ADC. Negative differential
input for primary ADC.
Single-Ended or Differential Analog Input 0. Analog input for the primary ADC. Positive differential
input for primary ADC.
Analog Ground.
Analog Supply Pin.
External Reference Positive Input for the Primary Channel. Analog input pin.
External Reference Negative Input for the Primary Channel. Analog input pin.
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.
General-Purpose Input and General-Purpose Output P0.1/SPI Clock/I
ADC7. This is a multifunction input/output pin. Single-ended or differential Analog Input 7.
Analog input for the auxiliary ADC.
Exposed Paddle. The 32-lead LFCSP_VQ has an exposed paddle that must be left unconnected.
