PIC18F2585-H/SP

PIC18F2585-H/SP application field and working principle

The PIC18F2585-H/SP is a type of embedded micro-controller (MCU) manufactured by Microchip. It falls under their 8-bit PIC family and is used in a number of applications requiring basic control and signal processing. There are several different types of PIC18F2585-H/SP MCUs, each optimised for different applications and users. This article aims to provide an overview of their application fields, working principle and main features.

Applications Fields

The PIC18F2585-H/SP family of micro-controllers are widely used in a range of applications that require basic control and signal-processing capabilities. These include medical systems, automotive systems, home appliances, industrial equipment, audio systems, and communications systems. MCUs in this family are particularly suitable for motor control, as they offer motor-speed control, high pulse-width modulation rate, and bidirectional motor control.

Working Principle

The PIC18F2585-H/SP micro-controllers are based on the PIC18 architecture, which utilises a Harvard-architecture-structured Harvard Machine-Level (HML) instruction set. The HML instruction set contains operations that allow the MCU to access memory and manipulate data. The memory and data manipulations are performed through the program counter, which keeps track of the location of the current instruction being executed. The MCU has two types of memory – program memory, which stores the program instructions, and data memory, which stores the data used by the program.

Features

The PIC18F2585-H/SP micro-controllers offer several features to enhance their performance. These include an instruction set with dedicated registers, a Programmable-Interrupt Controller (PIC), an 8-bit timer/counter to time/measure pulse widths, Power control/DMA (direct memory access) module, a power save mode, integrated real-time clock, and an integrated Programmable-Logic Interface (PLI). These features make the micro-controllers suitable for a wide range of applications.

Conclusion

The PIC18F2585-H/SP family of micro- controllers is an excellent choice for applications requiring basic control and signal-processing capabilities. Its suite of features, as well as its HML instruction set, make it suitable for a wide range of applications, including automotive systems, medical systems, audio systems, industrial equipment, and communications systems.
