The fast response rate and wide command set of the PIC16C620-04/P make it a suitable solution for complex industrial control systems.2.Automation.
The PIC16C620-04/P can be regarded as the hub of an automation system. Its unique features, such as its low power dissipation, small chip size and high performance, make it an obvious choice for industrial automation. As an embedded solution, the PIC16C620-04/P can be employed to construct an automation system consisting of both sensors and actuators.3.Data Display.
The PIC16C620-04/P can be used as the heart of a data display system. Its built-in intelligence and rich command set enables the PIC16C620-04/P to automatically respond to user input throughout the whole data display process.4.Communication.
In today’s fast-and-connected society, communication is an essential function. The PIC16C620-04/P supports both serial and parallel communications, making it an ideal solution for data exchange between microcontrollers and external devices.

Working Principle

The PIC16C620-04/P ECU is based on the same Mi core architecture as its predecessors. The Mi core is an 8-bit microcomputers architecture designed by Microchip Technology Inc. and runs on an 8-bit wide data bus. The architecture adopts the Harvard style, with the instruction and data being stored in separate memory elements.The PIC16C620-04/P is a medium-cost microcontroller featuring four 8-bit I/O ports, two timer and counter modules, a parallel slave port, two pulse-width modulation (PWM) outputs and one asynchronous serial port. All pins are in a 20-pin DIP package. The device is powered by an internal voltage regulator and supports both parallel and serial communications.The main memory of the PIC16C620-04/P is 16 Kilobyte of RAM, 4 Kilobyte of ROM, and 4 Kilobyte of EEPROM. All of these are mapped together to form a single, linear memory space. The PIC16C620-04/P supports up to two 16-bit counter and two 8-bit timer/counter modules. All interrupts are individually maskable. The PIC16C620-04/P also supports two PWM outputs and two independent internal oscillators.The device is programmable using the familiar Mi Assembly language. Languages such as C and Basic are also supported by third-party tools. The programmers can, of course, monitor and debug the code in real-time. The commands can also be tuned from distances, so the device wouldn\'t have to be physically connected all the time.

Conclusion

The PIC16C620-04/P is an economical, feature-rich 8-bit Electronic Control Unit suitable for most embedded applications. It features on-chip oscillators, four 8-bit I/O ports, two timer and counter modules, a parallel slave port, two pulse-width modulation (PWM) outputs and one asynchronous serial port. All these functions, combined with its powerful Mi core architecture and excellent instruction set, enables the device to respond to user input quickly, accurately and in real-time. The PIC16C620-04/P is a perfect solution for cost-sensitive, embedded application.
