The processor supports multiple instances of UART, Serial Peripheral Interface (SPI), I2C, Multichannel Audio Serial Port (MCASP), Enhanced Pulse Width Modulator (EPWM), Enhanced Quadrature Encoder Pulse (EQEP), ECAP, CAN with CAN-FD support and GPIO modules.
For I2C interfaces with open-drain output type buffer (MCU_I2C0 and WKUP_I2C0), an external pullup is recommended irrespective of peripheral usage and IO configuration. Refer Pin Connectivity Requirements section of device-specific data sheet.
When these open-drain output type buffer I2C interfaces are pulled to 3.3 V supply, the inputs have slew rate limit requirements. An RC is recommended to limit the slew rate.
An external pullup is recommended for the I2C interfaces with LVCMOS IOs emulated open-drain outputs. For the available LVCMOS IOs with emulated open-drain output I2C instances, refer the device-specific data sheet.
For more information, see the [FAQ] AM625 / AM623 / AM625SIP / AM625-Q1 / AM620-Q1 Custom board hardware design – I2C interface.
The number of peripheral instances available depends on the processor selection. The required interfaces can be configured using the SysConfig-PinMux tool based on the application.
For more details, refer the Peripherals chapter of the device-specific TRM.
