2.22.1 User Expansion Connector

The AM62P SK EVM supports RPi expansion interface using a 40-pin User expansion connector Mfr. Part# PEC20DAAN. Three mounting holes are oriented with the connector to allow for connection of any generic HAT boards.

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_B
  • 1x CLK: CLKOUT0
  • 10x GPI0: GPIOs from main domain
  • 5Vand 3.3V supply (current limited to 155 mA and 500 mA)

Each of the power supplies 5 V and 3.3V are current limited to 155 mA and 500 mA respectively. This is achieved by using two individual load switch TPS22902YFPR and TPS22946YZPR. Enable for the load switches are controllable by an I2C based GPIO port expander.

Signals routed from User Expansion connector are listed in Table 3-23.
