He talked about it’s very few advantages and it’s five disadvantages like UART, timer ,large number of sets, ADC and memory capacity. Then he continued how those disadvantages were overcome by many other microcontrollers, from PIC controller to the most frequent used microcontrollers like raspberry pi series and the arm series. Then he also told us about the various arm series like series 11 and how they are used in apple smart phones. The advantages and the applications of these microcontrollers were explained. Lastly he finished with a question section in which few of the students clarified their doubts.
