The processor family supports multiple instances of UART, Multichannel Serial Peripheral Interface (MCSPI), I2C, Multichannel Audio Serial Port (MCASP), Enhanced Pulse Width Modulator (EPWM), Enhanced Quadrature Encoder Pulse (EQEP), Enhanced Capture (ECAP), MCAN (Modular Controller Area Network) with Full CAN-FD support and GPIO. All LVCMOS IOs can be configured as GPIO.
For I2C interfaces with open-drain output type buffer (MCU_I2C0 and WKUP_I2C0), an external pull is recommended irrespective of peripheral usage and IO configuration. Refer Pin Connectivity Requirements section of device-specific data sheet.
When the open-drain output type buffer I2C interfaces are pulled to 3.3V supply, the inputs have slew rate limit specified. An RC can be used to limit the slew rate. For RC implementation, refer Starter Kit SK-AM62P-LP for implementation.
An external pullup is recommended for the I2C interfaces (I2C0-3) with LVCMOS IOs emulated open-drain outputs when the IOs are configured for I2C interface. For the available LVCMOS IOs with emulated open-drain output I2C instances, refer the device-specific data sheet.

[FAQ] AM62A7-Q1: Internal pull configuration registers for MCU_I2C0 and WKUP_I2C0
Above FAQs are generic and can also be used for AM62D-Q1 family of processors.
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.
