These peripherals include ADC, EUSART, Capture/Compare PWM modules, CCP modules, Windowed Watchdog timer, Brown-out Reset, Power-on Reset and Power-pin, I2C and SPI interfaces. These peripherals are specifically designed to provide easy, low cost, and robust operation with low power and low noise.

Working Principle

The PIC16LC554T-04I/SS microcontroller is an 8-bit, Harvard architecture microcontroller, which means it is based on a modified von Neumann architecture. This architecture divides space in instruction space, data space and program space. The instruction space includes the program memory that stores the sequence of machine language instructions and their addresses in the memory. The data space is where data and variables are stored. The program space contains the executable program the processor follows when executed. The PIC16LC554T-04I/SS implements the 8-bit Instruction Set Architecture (ISA) with provisions for 32-bit operations. This ISA consists of three categories of instructions: register operations, I/O, and memory operations. The microcontroller contains two basic types of operations: arithmetical operations and logical operations. These operations are performed on 16-bit registers, with each register containing 8-bit data. The microcontroller also contains a wide range of specialized registers for memory mapped I/O, interrupt vectors, and user defined flags and variables.

Conclusion

The PIC16LC554T-04I/SS microcontroller is a high-performance, embedded 8-bit microcontroller with a powerful instruction set and on-chip peripheral set, making it suitable for a wide range of applications requiring extreme accuracy and safety. Its working principle is based on a modified von Neumann architecture, with separate instruction, data and program storage. Furthermore, the microcontroller implements the 8-bit ISA, with instructions categories of arithmetical and logical operations, I/O and memory operations.
