Milestone of Microcontrollers

The document summarizes the evolution of microcontrollers from 1974 to 2009, listing key milestones in processing speed, transistor count, and applications. It outlines the introduction of early microcontrollers like the Motorola 6800 and Intel 8048, which had integrated memory, timers, and I/O ports. Later microcontrollers like the NEC V25 and NXP LPC1100 added features like serial communications and analog to digital conversion, finding use in consumer electronics and other applications. The timeline shows the progression towards higher speeds, more transistors, and increasingly integrated and full-featured microcontroller chips over several decades.
