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...]
