Inside any electronic device, from an old television remote to a global positioning system, there will be at least one microcontroller unit (MCU) and, in many cases, several. MCUs are used in ...

While microcontroller specs may be the first thing engineers look at when deciding on a device for their system, the ecosystem that surrounds the microcontroller is certainly very important, and ...

This project presents a custom-designed RISC-based microcontroller implemented using Verilog, featuring a simplified instruction set, Harvard architecture, and non-pipelined execution. The design ...

When designing a system, one of the most important design decisions is choosing what voltage domain(s) to use. Some voltage domains, such as 5 V, are good for noisy and harsh operating environments ...

This paper describes the design and implementation of a version of the 8051 microcontroller, one of the most commercially used microcontrollers in FPGA with reconfigurable instruction set.

This project implements a custom 8-bit microcontroller on an FPGA using VHDL/Verilog. It includes a simple RISC-style instruction set, an ALU, register file, program counter, control unit, and memory.

Members can download this article in PDF format. In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to ...

Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...
