NAME F1 I2C_ADDR Analog I/O Digital core I/O and control pins Analog input Sets the I2C address for both I2C ports as well as determine the master and slave devices for memory code sharing. F10 BUSPOWERZ (GPIO10) Analog Input Digital core I/O and control pins Input (Hi-Z) General purpose digital I/O 10. Sampled by ADC at boot. Tie pin to LDO_3V3 through a 100-kΩ resistor to disable PP_HV and PP_EXT power paths during dead-battery or no-battery boot conditions. Refer to the BUSPOWERZ table for more details. F11 RESETZ (GPIO9) Digital I/O Digital core I/O and control pins Push-pull output (Low) General purpose digital I/O 9. Active-low reset output when VOUT_3V3 is low (driven low on start-up). Float pin when unused. F2 UART_RX Digital input Port multiplexer pins Digital input UART serial receive data. Connect pin to another TPS65982 UART_TX to share firmware. Connect UART_RX to UART_TX when not connected to another TPS65982 and ground pin through a 100-kΩ resistance. F3 No Ball Blank Ground and no connect pins — Unpopulated ball for A1 marker and unpopulated inner ring. F4 SWD_DATA Digital I/O Port multiplexer pins Resistive pull high SWD serial data. Float pin when unused. F5 GND Ground Ground and no connect pins — Ground. Connect all balls to ground plane. F6 F7 F8 F9 No Ball Blank Ground and no connect pins — Unpopulated ball for A1 marker and unpopulated inner ring. G1 LDO_3V3 Power Low-current power pins — 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. G10 GPIO6 Digital I/O Digital core I/O and control pins Hi-Z General purpose digital I/O 6. Float pin if it is configured as a push-pull output in the application. Ground pin with a 1-MΩ resistor when unused in the application. G11 GPIO3 Digital I/O Digital core I/O and control pins Hi-Z General purpose digital I/O 3. Float pin if it is configured as a push-pull output in the application. Ground pin with a 1-MΩ resistor when unused in the application. G2 R_OSC Analog I/O Digital core I/O and control pins Hi-Z External resistance setting for oscillator accuracy. Connect R_OSC to GND through resistance RR_OSC. G3 No Ball Blank Ground and no connect pins — Unpopulated ball for A1 marker and unpopulated inner ring. G4 SWD_CLK Digital input Port multiplexer pins Resistive pull high SWD serial clock. Float pin when unused. G5 GND Ground Ground and no connect pins — Ground. Connect all balls to ground plane. G6 G7 G8 G9 No Ball Blank Ground and no connect pins — Unpopulated ball for A1 marker and unpopulated inner ring. H1 VIN_3V3 Power Low-current power pins — Supply for core circuitry and I/O. Bypass with capacitance CVIN_3V3 to GND. H10 PP_CABLE Power High-current power pins — 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. H11 VBUS Power High-current power pins — 5-V output from PP_5V0. Input or output from PP_HV up to 20 V. Bypass with capacitance CVBUS to GND. H2 VOUT_3V3 Power Low-current power pins — Output of supply switched from VIN_3V3. Bypass with capacitance COUT_3V3 to GND. Float pin when unused. H3 No Ball Blank Ground and no connect pins — Unpopulated ball for A1 marker and unpopulated inner ring. H4 GND Ground Ground and no connect pins — Ground. Connect all balls to ground plane. H5 H6 GPIO8 Digital I/O Digital core I/O and control pins Hi-Z General purpose digital I/O 8. Float pin if it is configured as a push-pull output in the application. Ground pin with a 1-MΩ resistor when unused in the application. |
