Working Principle

The MB90F543GSPF-GS-9009 uses an ARM Cortex-M3 processor core, written in embedded C language. The processor core is responsible for the efficient execution of application code, while the SCI (Serial Communication Interface) interface provides the communication link between the processor and external peripherals. The 8K bytes of instruction RAM memory and the 24K bytes of external SRAM are used as needed, allowing the user to store and run unlimited amounts of data.

The embedded C language allows the configuring of I/O devices’ specific functions, such as serial data transmission and reception, through dedicated registers for each port. The processor also offers access to ports for further configuring I/O’s, both on and off-chip, such as keyboard, ADC, DAC, CAN bus, Infrared, and 2-wire serial devices.

The processor also contains an interrupt controller for managing and managing interrupt events, as well as an on-chip clock generator for configuring external memory and other peripheral interfaces. The two USB ports provide a convenient connection for external USB devices, and both USB 2.0 and 3.0 protocols are supported.

In summary, the MB90F543GSPF-GS-9009 is a compact, powerful and user-friendly microcontroller that is suitable for a wide range of embedded applications. It provides the combination of a powerful Cortex-M3 processor core and optimized peripherals at an attractive price point.
