4 - Microcontroller

 

4.1 - Overview

 

The microcontroller on Karbon 300 controls several systems, including:

  

Automotive ignition power sensing

 

CAN bus

 

DIO

 

Status LEDs

 

Power management and wake-up

 

DisplayPort CEC and persistent EDID

 

 

A segment is exposed for user control via two serial ports. By reading and writing to these serial

 

ports, the user can send and receive CAN messages, read/set the DIO state, and select from a number

 

of configuration options. One port is dedicated to K300’s CAN bus, while another doubles as a serial

 

terminal and the DIO interface. Any configuration settings may be saved to non-volatile memory. This

 

means that upon a long power-off, the MCU settings will be retained.

  

 

To learn more about how to use the Karbon series MCU and Pykarbon interface tools, visit our 

Karbon

 

Series technical support site

5 - Power Management

 

5.1 - Wake-Up Events

 

Karbon 300 supports multiple power states. The wake-up events can be configured in the MCU and

 

BIOS. This section describes the power management functions you can perform and gives

 

information on protection circuitry for power adapters.
