4 Peripherals

Feature List

• Two I2C controllers: one in the main system and one in the low-power system

• Standard mode (100 Kbit/s)

• Fast mode (400 Kbit/s)

• Up to 5 MHz, yet constrained by SDA pull-up strength

• Support for 7-bit and 10-bit addressing, as well as dual address mode

• Supports continuous data transmission with disabled Serial Clock Line (SCL)

• Supports programmable digital noise filter

Users can program command registers to control I2C interfaces, so that they have more flexibility.

For details, see ESP32 Technical Reference Manual > Chapter I2C Controller.

Pin Assignment

For regular I2C, the pins used can be chosen from any GPIOs via the GPIO Matrix.

For more information about the pin assignment, see ESP32 Series Datasheet > Section Peripheral Pin

Configurations and ESP32 Technical Reference Manual > Chapter IO_MUX and GPIO Matrix.

4.2.5

I2S Interface

The I2S Controller in the ESP32 chip provides a flexible communication interface for streaming digital data in

multimedia applications, particularly digital audio applications.

Feature List

• Master mode and slave mode

• Full-duplex and half-duplex communications

• A variety of audio standards supported

• Configurable high-precision output clock

• Supports PDM signal input and output

• Configurable data transmit and receive modes

For details, see ESP32 Technical Reference Manual > Chapter I2S Controller.

Pin Assignment

The pins for the I2S Controller can be chosen from any GPIOs via the GPIO Matrix.

For more information about the pin assignment, see ESP32 Series Datasheet > Section Peripheral Pin

Configurations and ESP32 Technical Reference Manual > Chapter IO_MUX and GPIO Matrix.

4.2.6 Remote Control Peripheral

The Remote Control Peripheral (RMT) controls the transmission and reception of infrared remote control

signals.
