I/O

The GPIOs of a GR5526 SoC can be connected to various digital and mixed-signal interfaces, and the features are as follows:

  • Up to 34 General Purpose I/Os (GPIOs): normal digital GPIOs in MCU domain
  • 8 AON_GPIOs: digital GPIOs in the AON domain
  • 8 MSIOs: digital and analog mixed-signal GPIOs, no interrupt
  • All I/Os have internal pull up/down registers
  • All I/Os except fast speed I/Os (QSPI, OSPI, and XQSPI) can retain their last state when the system enters the sleep mode.
  • GPIO_0–GPIO_15 are supplied by VDDIO_1.
  • MSIO_A0–MSIO_A7 are supplied by VBATL.
  • AON_GPIO_0–AON_GPIO_7 and GPIO_16–GPIO_33 are supplied by VDDIO_0.
