User Expansion Connector

The AM62x-Low Power SK EVM supports RPi expansion interface using a 40-pin User expansion connector Mfr. Part# PEC20DAAN. Four mounting holes must be oriented with the connector to allow for connection of these boards.

The following interfaces and IOs are included on to the 40 pin User Expansion connector.

  • 2x SPI : SPI0 with 2 CS and SPI2 with 3 CS
  • 2x I2C: SoC_I2C0 and SoC_I2C2
  • 1x UART: UART5
  • 2x PWM: EHRPWM0_A, EHRPWM1_B1xCLK: CLKOUT0
  • 10x GPI0: GPIOs from main domain
  • 5V and 3.3V supply (current limited to 155mA and 500mA)

Each of the power supplies 5V and 3.3V are current limited to 155mA and 500mA respectively. This is achieved by using two individual load switches TPS22902YFPR and TPS22946YZPR. The Enable signals for the load switches is driven via I2C based GPIO Port expander.
