MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The 8085 is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology that can address 64K Byte of memory. It has 40 pins DIP (Dual Inline Package) IC.

Detailed explanation-2: -The 40 pins of the microprocessor can be divided into six groups such as address bus, data bus, control signals & status signals; power supply & frequency, externally started signals and serial input/output ports.

Detailed explanation-3: -The Pin diagram of the 8085 microprocessor has 40 pins that are classified into seven groups: address bus, data bus, control signals and status signals, power supply, and frequency, Reset signals, DMA signals, and serial input/output ports.

Detailed explanation-4: -8086 was the first 16-bit microprocessor available in 40-pin DIP (Dual Inline Package) chip.

Detailed explanation-5: -The 8085 is supplied in a 40-pin DIP package. To maximise the functions on the available pins, the 8085 uses a multiplexed address/data (AD0-AD7) bus. However, an 8085 circuit requires an 8-bit address latch, so Intel manufactured several support chips with an address latch built in.
