HIGH-CURRENT POWER PINS PP_5V0 A11, B11, C11, D11 Power NA 5-V supply for VBUS. Bypass with capacitance CPP_5V0 to GND. Tie pin to GND when unused PP_HV A6, A7, A8, B7 Power NA HV supply for VBUS. Bypass with capacitance CPP_HV to GND. Tie pin to GND when unused PP_CABLE H10 Power NA 5-V supply for C_CC pins. Bypass with capacitance CPP_CABLE to GND when not tied to PP_5V0. Tie pin to PP_5V0 when unused. VBUS H11, J10, J11, K11 Power NA 5-V output from PP_5V0. Input or output from PP_HV up to 20 V. Bypass with capacitance CVBUS to GND. LOW-CURRENT POWER PINS VIN_3V3 H1 Power NA Supply for core circuitry and I/O. Bypass with capacitance CVIN_3V3 to GND. VDDIO B1 Power NA VDD for I/O. Some I/Os are reconfigurable to be powered from VDDIO instead of LDO_3V3. When VDDIO is not used, tie pin to LDO_3V3. When not tied to LDO_3V3 and used as a supply input, bypass with capacitance CVDDIO to GND. VOUT_3V3 H2 Power NA Output of supply switched from VIN_3V3. Bypass with capacitance COUT_3V3 to GND. Float pin when unused. LDO_3V3 G1 Power NA Output of the VBUS to 3.3 V LDO or connected to VIN_3V3 by a switch. Main internal supply rail. Used to power external flash memory. Bypass with capacitance CLDO_3V3 to GND. LDO_1V8A K1 Power NA Output of the 3.3 V or 1.8 V LDO for Core Analog Circuits. Bypass with capacitance CLDO_1V8A to GND. LDO_1V8D A2 Power NA Output of the 3.3 V or 1.8 V LDO for Core Digital Circuits. Bypass with capacitance CLDO_1V8D to GND. LDO_BMC E1 Power NA Output of the USB-PD BMC transceiver output level LDO. Bypass with capacitance CLDO_BMC to GND. TYPE-C PORT PINS C_CC1 L9 Analog I/O Hi-Z Output to Type-C CC or VCONN pin. Filter noise with capacitance CC_CC1 to GND. C_CC2 L10 Analog I/O Hi-Z Output to Type-C CC or VCONN pin. Filter noise with capacitance CC_CC2 to GND. RPD_G1 K9 Analog I/O Hi-Z Tie pin to C_CC1 when configured to receive power in dead-battery or no-power condition. Tie pin to GND otherwise. RPD_G2 K10 Analog I/O Hi-Z Tie pin to C_CC2 when configured to receive power in dead-battery or no-power condition. Tie pin to GND otherwise. C_USB_TP K6 Analog I/O Hi-Z Port side Top USB D+ connection to Port Multiplexer. C_USB_TN L6 Analog I/O Hi-Z Port side Top USB D– connection to Port Multiplexer. C_USB_BP K7 Analog I/O Hi-Z Port side Bottom USB D+ connection to Port Multiplexer. C_USB_BN L7 Analog I/O Hi-Z Port side Bottom USB D– connection to Port Multiplexer. C_SBU1 K8 Analog I/O Hi-Z Port side Sideband Use connection of Port Multiplexer. C_SBU2 L8 Analog I/O Hi-Z Port side Sideband Use connection of Port Multiplexer. PORT MULTIPLEXER PINS SWD_DATA F4 Digital I/O Resistive Pull High SWD serial data. Float pin when unused. SWD_CLK G4 Digital Input Resistive Pull High SWD serial clock. Float pin when unused.
