One USB2.0 interface, slave mode only
Three SPI interfaces One standard SPI interface supports only master mode
One LCD-dedicated SPI interface
One camera-dedicated SPI interface
Four 12-bit ADC interfaces, can detect voltages ranging from 0 V to VBAT.
Two SDIO interfaces SDIO2 for WLAN SDIO1 is used for SD card connection
and needs to be multiplexed by a dedicated pin that supports multiplexing. For
more details, see the pin multiplexing table.
One PCM interface
One I2C interface, master mode only
One headset interface
One MIC interface, bias voltage ranging from 2.2 V to 3 V, V
norm
=2.2 V
One SPK interface, supporting differential output only, with built-in class-AB or
class-D power amplifier. Maximum output power:
Class AB: 600 mW@4.2 V, with an 8 Ω load.
Class D: 800 mW@4.2V, with an 8 Ω load.
One EAR interface, for a maximum of 50 mV power when loading 32 Ω.
If the output power is not enough, connect this interface to an external power
amplifier.
