IInd Generation Microprocessor :

The second generation microprocessor by using n MOS technology seemed in the market in 1973.

The Intel  8080, of nMOS  technology  and an 8-bit  microprocessor was  developed  in 1974  which required only 2 additional  devices to design a functional  CPU. Since 8080 was n MOS device, it was Quicker and had several more instructions than 8008 that facilitated the programming. The advantages of IInd generation microprocessors were:

 

  1. Large chip size (170 x 200 mil) with 40-pins.
  2. More chips on decoding circuits.
  3. Ability to address large memory space (64-K Byte) and I/O ports (256).
  4. More powerful instruction sets.
  5. Dissipate less power.
  6. Better interrupt handling facilities.
  7. Cycle time reduced to half (1.3 to 9 µ sec.)
  8. Sized 70x200 mil) with 40-pins.
  9. Less Support Chips Required
  10. Used Single Power Supply
  11. Faster Operation
