Working Principle

DSPIC33FJ128MC708T-I/PT microcontrollers operate on the same principle as other modern MCUs. It operates using an instruction set, using programming language such as Assembly or C. In addition, it can be operated using embedded software, such as Boot Loader and firmware. Instructions are loaded into the microcontroller in the form of a program, which is stored in the Flash memory. The program is then executed on the microcontroller, performing the instructions in order to control the connected devices.

The microcontroller interacts with the external devices or peripherals by passing information in and out of the microcontroller by means of the two ports. The Control register, or the Program Counter (PC), enables the microcontroller to select the appropriate instruction to be executed, which is stored in the Flash memory. The control register can also be programmed to control the peripheral devices. The Data register, or the Stack Pointer (SP), enables the microcontroller to store data which has been sent from or retrieved from the external devices.

The microcontroller uses various types of permanent and temporary variables, known as registers and stack memory. Registers store data that is used frequently. The stack memory stores data that is used temporarily. The microcontroller can store up to 32 bytes of data in each register, which is sufficient for the most common loop-based operations. The stack memory stores only 8 bytes of data, enough for short term operations, such calculation of return address after an indirect jump.

DSPIC33FJ128MC708T-I/PT microcontrollers include an on-chip peripherals, enabling them to interact with external devices. These peripherals consist of I/O pins, analog/digital converters, timers, comparators, and UARTs. The external devices are interfaced with the microcontroller, via the I/O pins. The device drivers allow the microcontroller to detect and control the connected devices. The timer is used to generate time delays and interrupt, and the UART is used to transfer serial data with the connected devices.

Conclusion

The DSPIC33FJ128MC708T-I/PT is a powerful, low-power, and high-performance 8-bit microcontroller. It is well-suited for a variety of embedded applications, such as communications, motor control, lighting control, and industrial control. It includes a range of digital signal controllers and peripherals, allowing it to interact with a range of external devices. It operates on the same principle as other modern MCUs, and it enables the programmer to store program instructions and data in the Flash memory.
