I/O DC Parameters
This section includes the DC parameters of the following I/O types:
General Purpose I/O and High-Speed General Purpose I/O (GPIOxx/HSGPIOxx)
Low Voltage I/O (LVIO)
Ultra High Voltage I/O (UHVIOxx)
WLAN
PMIC_GPO, PMIC_PWRON, PMIC_STDBY, PMIC_INT, PMIC_PWDRV, PMIC_SE,
PMIC_CHRGLED, and PMIC_LED
Ethernet (ETH)
Analog RGB
ADC subsystem (ADIN)
Digital and analog USB (DIG_USB, AN)USB)
The I/O type associated to each I/O signal of the module is shown in the paragraph “Module
Pinout” of Chapter 1.
The following table shows the General Purpose I/O and High-Speed General Purpose I/O
(GPIOxx/HSGPIOxx) DC parameters. The “xx” reference signifies the supply voltage level.
