Design and simulation of electronic circuit

Abstract

With the advancement of technology, microcontroller (MCUs) has been an integral part of today’s society. With the rise of popularity for its functionality and processing capability, MCUs are used on almost all electronic systems. 8 and 16-bit processors are typically used for low processing capacity due to the ease of implementation and low cost. While 32 and 64-bit processors are used for high processing capacity. The selection of microcontrollers is different based on the choice of integrated circuits, operating environments, and programming complexity

Microcontrollers contain microprocessors allowing mathematical and logical operations, memory units such ad RAM, ROM, EPROM and EEPROM, input-output interfaces, analogy-to-digital conversion (ADC), pulse width modulation (PWM) and various control and communication modules. There are many MCUs available in the market to date, however, the MCU of interest in this paper is PIC18F46J50.

PIC18F46J50 is an 8bit MCU, integrated with full-speed USB 2.0 belongs to the high-performance category of the PIC family. The low power and high-performance chip allow for application requiring cost-effective and low power USB solutions with a robust peripheral set in a small package. Altium designer is a designer tool used to integrate this MCU along with other peripherals to create an MCU for a mini-computer and control system.

This report aims to document and understand the process of circuit design of an MCU using PIC18F46J50 with the use of Altium designer.
