Major companies such as Texas Instruments, PIC, ST, and others provide many microcontrollers with different features and prices. But when it comes to differentiating these microcontrollers based on features and form factor versus price, choosing the right MCU for application between them will be very difficult. However, in 2008, a Taiwan-based semiconductor company called Nuvoton which was spun off as a subsidiary of Winbond offered many useful cost-effective microcontrollers, cutting-edge … [Read more...]
What is AVR Microcontroller : PinOut, Working & Its Applications
The advanced version of a microprocessor is a microcontroller that includes a CPU, Interrupts controller, RAM, ROM, I/O unit, etc. A microcontroller is mainly used for the operation of high-speed signal processing in an embedded system. So it performs like a major component while designing an embedded system. There are different kinds of microcontrollers available which are used based on requirements like 8051, PIC, AVR, etc. So this article gives brief information on one of the types of … [Read more...]
What is I2C Protocol : Architecture, Timing Diagram & Its Applications
In the process of establishing a connection between multiple devices in a microcontroller, the data and address line of every single device would take up important pins in the microcontroller which leads to more traces on the PCB board. And also it requires more components which further results in cost enhancement of the system and they are even easily subjective to noise and intrusion. So, to stay back from this complication Philips introduced IC buses which were also called I2C in the year the … [Read more...]
ATtiny85 Microcontroller & Its Working
In 1999, the ATMEL introduced ATtiny Microcontrollers. There are several 8-pin based ATtiny microcontrollers are available like ATtiny11, ATtiny12, ATtiny22, ATtiny26, ATtiny24, ATtiny44, ATtiny84, ATtiny25, ATtiny45, ATtiny202/204/402/804/404 & ATtiny85 microcontroller with microchip technology. These microcontrollers became popular as tiny AVR controllers. These are designed in small size with all the features of a microcontroller. They contain few Input-Output pins and limited program … [Read more...]
8051 Microcontroller Projects for Engineering Students
In 1981, Intel Company manufactured the first 8-bit 8051 based microcontroller and it was referred to as MCS-51 (Microcontroller System-51). The components such as ROM, RAM, timer, input/output ports, serial communication, and interrupt logic all are in-built in a controller so that the size of the overall system will be small. When we design a system with the help of a microcontroller, it will be not bulky. So, it can be used in different applications for a specific operation like electronic … [Read more...]
What is PIC Microcontroller and Its Architecture
PIC microcontroller was developed in the year 1993 by microchip technology. The term PIC stands for Peripheral Interface Controller. Initially this was developed for supporting PDP computers to control its peripheral devices, and therefore, named as a peripheral interface device. These microcontrollers are very fast and easy to execute a program compared with other microcontrollers. PIC Microcontroller architecture is based on Harvard architecture. PIC microcontrollers are very popular due to … [Read more...]
