(By default is GPIO input, internal pull-low) PWM channel 0, output. 43 VCC1V2 P +1.2V core voltage. This is internal regulator output and core voltage input. Connect 4.7uF and 0.1uF decoupling capacitors to GND. 44 VCCIO3V3 P +3.3V supply voltage. This is the supply voltage for all the I/O ports. Connect a 0.1uF decoupling capacitor. 45 XI/CLKIN AI 12MHz clock frequency. Input to the Oscillator circuit. 46 XIO AI/O Output from the Oscillator amplifier. Input to the internal clock generator circuit. 47 VCC1V2 P +1.2V core voltage. This is internal regulator output and core voltage input. Connect 4.7uF and 0.1uF decoupling capacitors to GND. 48 VUSB3V3 P +3.3V supply voltage. This is the supply voltage for USB Device I/O ports. Connect 10uF and 0.1uF decoupling capacitors. This pin can be connected to all +3.3V power supply pins without the 10uF capacitor. 49 D_DM AI/O USB Device bidirectional DM line. 50 D_DP AI/O USB Device bidirectional DP line. 51 DRREF AI USB Device reference voltage input. Connect 12k ohm +/- 1% resistor to GND. 52 ADC3 AI 8-bit A/D converter 3, input. 53 ADC2 AI 8-bit A/D converter 2, input. 54 ADC1 AI 8-bit A/D converter 1, input. 55 ADC_REFP P ADC positive reference voltage. 56 VCC3V3A P +3.3V supply voltage. This is the supply voltage for Analog I/O ports. Connect 10uF and 0.1uF decoupling capacitors. This pin can be connected to all VCC3V3 pins without the 10uF capacitor. 57 AGND P Analog Ground. 58 DAC_REFP P DAC positive reference voltage. |
