PIN DESCRIPTIONS
PIN
NAME
DESCRIPTION
H6
VALIVE
The Always-On Low Power LDO Output. Bypass to GA with a 1μF high quality ceramic capacitor.
H7
AUX0
The Auxiliary ADC Input AUX0.
H8
GD
The Ground Node of the ADC Circuit in the IC.
H9
XPOS
One of ADC Input, Internally Configured as the Touch Screen Force-Sense Node XPOS with an
internal force switch.
J1
CLK32
The 32kHz Oscillation Output, OD. A pull-up resistor at load end in range of 150kΩ to 300kΩ is
recommended.
J2
VP1
The Switch Power Input Node of the Step-down DC/DC REG1. Same function as pin H2.
J3
OUT1
The Step-down DC/DC REG1 Feedback Node. Connect it to the output node of REG1.
J4
XTAL-
The 32kHz Oscillator Crystal Node. This node is pick-up node. Connect it to any terminal of an
external crystal.
J5
XTAL+
The 32kHz Oscillator Crystal Node. This node is driving node. Connect it to any terminal of an
external crystal.
J6
VBBAT
The Back-up Battery Node. Connect it to the positive node of a back-up battery or storage super cap.
The back-up battery charger circuit charges battery or super cap at this node with limited current
and outputs a programmable voltage after charging for powering the always-on low power LDO.
J7
AUX1
The Auxiliary ADC Input AUX1.
J8
BBCIN
The Back-up Battery Charger Circuit Input. Bypass to GA with a 1μF high quality ceramic capacitor.
J9
AUX2
The Auxiliary ADC Input AUX2.
