3. Integrated oscillator for clock generation
4. Support for multiple power modes, including power-down and sleep modes
5. Multiple communication interfaces, including I2C and SPI
6. Built-in keyboard scanning and decoding algorithms
7. Programmable LED control for indicator lights
Pinout
An embedded controller typically consists of a microcontroller, memory, input/output (I/O) interfaces, and other peripheral components. The microcontroller is the heart of the embedded controller and is responsible for executing the program code that controls the device. The memory is used to store the program code and data, while the I/O interfaces allow the embedded controller to communicate with other devices or systems. By integrating a dedicated controller into a system, designers can optimize the performance and functionality of the system, while also reducing its size, cost, and power consumption.
