Working Principle

The PIC14000T-20I/SS microcontroller operates in two modes: Accumulator Based and RISC (Reduced Instruction Set Computing).In Accumulator Based mode, it consists of a single Accumulator, a Program Counter and an Instruction Bank. The Accumulator is used to store the intermediate results of computation and used to move the data between the internal and external memory. The Program Counter is used to store the address of the Instruction to be executed. The Instruction Bank consists of 80 instructions divided into five groups; Conditional Output, Conditional Input, Conditional Jump, Arithmetic and Miscellaneous Operations. In RISC mode, it instead consists of three independent General Purpose Registers (GPRs), an Internal Stack, a Program Counter and Instruction Analyzer which is used to identify the instruction type and to fetch the associated parameters from the data memory.The PIC14000T-20I/SS uses an 8-bit data bus for data manipulation and the 16-bit instruction bus for fetching the instructions from the instruction memory. The instruction memory consists of a programmable Flash memory and an 8K x 16bits SRAM.

Conclusion

The PIC14000T-20I/SS is a powerful 8-bit microcontroller with a wide range of applications. It is mainly used in embedded systems, automotive, industrial control and consumer applications. It operates in two modes: Accumulator Based and RISC, and it consists of an 8-bit data bus, a 16-bit instruction bus, an 8-bit DMA controller, an 8-channel 13-bit A/D converter and two 8-bit and one 16-bit Timers. With its high speed, low power consumption and extended temperature range, the PIC14000T-20I/SS is a reliable choice for many applications.
