Types of Microcontroller
Here are important types of Microcontroller:
8 bit Microcontroller 16 bit Microcontroller 32 bit Microcontroller Embedded Microcontroller External memory Microcontroller
History of Microprocessor
Here, are the important landmark from the history of Microprocessor
Fairchild Semiconductors invented the first IC (Integrated Circuit) in 1959. In 1968, Robert Noyce, Gordan Moore, Andrew Grove found their own company Intel. Intel grew from 3 man start-up in 1968 to industrial giant by 1981. In 1971, INTEL created the first generation Microprocessor 4004 that would run at a clock speed of 108 kHz From 1973 to 1978, second-generation 8-bit microprocessors were fabricated like Motorola 6800 and 6801, INTEL-8085, and Zilog’s-Z80. In 1978, Intel 8008 third-generation process came into the market. In the early 80s, Intel released fourth-generation 32-bit processors. In 1995, intel released in fifth-generation 64-bit processors .
History of Microcontroller
Here, are important landmarks from the history of Microcontroller:
First used in 1975(Intel 8048) The introduction of EEPROM in 1993 The same year, Atmel introduced the first microcontroller using Flash memory.
