Working Principle

The S9S12VR48AF0CLC microcontroller’s architecture is based on a Harvard Memory System, where the program and data memories are kept separate. This architecture allows for the highest access speed for both system code and RAM data. It also supports 8 million byte real-time program and RAM data.

The microcontroller\'s ROM provides pre-defined libraries for all major peripherals, including Timers, Interrupts, System Events, and I/O Registers. The on-chip FLASH memory can store program code and data during power-down condition. The LCD controller allows display of 1 to 256 characters on the LCD display.

The microcontroller offers three operating modes, depending on the application requirements – Normal, Power-down, and Stop2 mode. Each operating mode switches the clock rates, frequency of interrupts, and power consumption. This ensures that the operation is always performed with the lowest power and highest efficiency.
