MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Intel purchased the rights from Nippon Calculating Machine Corporation and launched the Intel® 4004 processor and its chipset with an advertisement in the November 15, 1971, issue of Electronic News: ‘’Announcing A New Era In Integrated Electronics.”

Detailed explanation-2: -The Intel 4004 was the world’s first microprocessor-a complete general-purpose CPU on a single chip. Released in March 1971, and using cutting-edge silicon-gate technology, the 4004 marked the beginning of Intel’s rise to global dominance in the processor industry.

Detailed explanation-3: -The first generation microprocessors were introduced in the year 1971-1972 by Intel Corporation. It was named Intel 4004 since it was a 4-bit processor. It was a processor on a single chip. It could perform simple arithmetic and logical operations such as addition, subtraction, Boolean OR and Boolean AND.

Detailed explanation-4: -The first microprocessors were designed and manufactured in the 1970s. Intel’s 4004 of 1971 is widely regarded as the first commercial microprocessor. Designers predominantly used MOSFET transistors with pMOS logic in the early 1970s, switching to nMOS logic after the mid-1970s.
