Working Principle of PIC12F1840-I/SN

The PIC12F1840-I/SN works on a Harvard architecture, which is based on the Von Neumann architecture. It consists of two memories, a Program Memory (PM) and a Data Memory (DM). The Program Memory stores the instruction code which is executed by the processor. The Data Memory, on the other hand, stores data that is manipulated by the program code. The processor can access the Program Memory or Data Memory and can modify the contents of the Data Memory.

The PIC12F1840-I/SN has a CPU core that can fetch, decode, and execute instructions from the Program Memory. Each instruction is 16 bits wide and is either a single cycle or multi-cycle architecture. The PIC12F1840-I/SN can generate interrupt signals in response to events such as timer/counter overflows, software interrupts, and external interrupts. In addition, the device has several I/O ports, which enables it to interact with external peripherals.

The PIC12F1840-I/SN includes several peripherals and support functions. For example, it includes a 10-bit A/D converter, two 8-bit timer/counters, a watchdog timer, and a serial port. The device also includes an enhanced interrupt controller, which allows the CPU to respond quickly to interrupts. The device also includes an Xtal oscillator, Vcap, and an onboard low power voltage reference.
