Additionally, the D12321VF20V provides a wide range of external memory options including SRAM and flash.

Working Principle

The D12321VF20V microcontroller operates on a two-wire serial bus where data is transmitted between two controllers. This bus is capable of connecting up to four slave controllers and a master controller. The microcontroller consists of four basic blocks: a CPU, an interrupt controller, a memory controller, and a timer. When a request is issued to the master controller, the CPU sends a signal to the interrupt controller, which then sends an interrupt signal to the timer. The timer then triggers the request for data from the slave controllers, which then sends the data back to the master controller.

Subsequently, the slave controllers send the read/write requests back to the CPU. The CPU then responds with an acknowledgement that it has received the request. The processor then interacts with the memory controller to access the required data. Once the data has been accessed and processed, the slave controller sends an acknowledge signal back to the processor indicating that the data has been received and stored, and then the data is sent to the requesting master controller.

The D12321VF20V has a built-in watchdog timer that monitors the execution of the processor. If a fault occurs or the program stalls, the watchdog timer will reset the processor and start the process again. This feature helps to ensure that the processor is running properly and increases the system reliability. The microcontroller also has a low power mode that can be used to reduce the static power consumption.

The D12321VF20V is a highly versatile and powerful microcontroller. With a wide range of integrated features and peripherals, the D12321VF20V provides the user with maximum flexibility and robust programming options. Its wide range of features, and its integrated peripherals, make it ideal for a variety of applications that demand low power consumption and accuracy.
