PIN TYPE(2) REST STATE ASSOCIATED ESD SUPPLY DESCRIPTION
NAME NO.
VDD3V3 B2 PWR N/A N/A 3.3V Supply Voltage
VDD1V8 D2, E3 PWR N/A N/A 1.8V Supply Voltage
VSS A3, D3 GND N/A N/A GND
RESETB D1 I N/A VDD1V8
  • Active Low Reset
  • Upon deassertion of RESETB, the repeater is enabled and be in eUSB2 default mode awaiting configuration from eDSPr or eUSPr.
  • If RESETB is not actively controlled, a pullup resistor 100kΩ to VDD1V8 is required.
SCL C3 I Internal pulldown 1MΩ typical (disabled after reset)(1) VDD1V8 I2C Clock Device Mode Matrix SCL SDA Mode

GPIO2 C2 I/O Internal pulldown 1MΩ typical (disabled after reset) VDD1V8
  • In I2C mode GPIO2 is an open-drain active low level interrupt output. Connect GPIO2 to input of APU and a pullup resistor to use interrupt features
  • In non I2C mode GPIO2 defaults to USB configuration input at power up reset.
  • When a pullup resistor is used to set high input, ensure VIH is met accounting for internal pulldown as small as 500kΩ
  • GPIO2 is an open-drain output after reset and can be left floating when not used.
GPIO0 B1 I/O Internal pulldown 1MΩ typical (disabled after reset)(1) VDD1V8 Defaults to an input mode at power up reset. RESETB assertion and deassertion or soft reset reverts GPIO0 to input mode
  • In I2C mode GPIO0 defaults to control Carkit UART mode: active low to enable Carkit UART mode. Default Carkit UART direction is DP → eDP (RX) and eDN → DN (TX). GPIO0 must be pulled up to be in USB repeater mode.
  • In non I2C mode GPIO0 defaults to USB configuration input at power up reset.
  • When a pullup resistor is used to set high input, ensure VIH is met accounting for internal pulldown as small as 500kΩ
GPIO1 C1 I/O Internal pulldown 1MΩ typical (disabled after reset)(1) VDD1V8 Defaults to an input mode at power up reset. RESETB assertion and deassertion or soft reset reverts GPIO1 to input mode
  • In I2C mode GPIO1 defaults to debug input
  • In non I2C mode GPIO1 defaults to USB Configuration input at power up reset.
  • When a pullup resistor is used to set high input, ensure VIH is met accounting for internal pulldown as small as 500kΩ

(1) When configured as an input but not actively driven, use 1MΩ external pulldown to strap low.
(2) I = input, I/O = input or output, PWR= power, GND = ground
