Why 8085 processor is called 8 bit processor?

The 8085 processor is called an 8-bit processor because its data bus can only transfer 8 bits of data at a time, meaning it can process information in units of 8 binary digits simultaneously; essentially, all its internal registers and operations are designed to handle data in 8-bit chunks. 

Key points about the 8085 processor:

Data bus width:

The primary reason for calling it an 8-bit processor is that its data bus is 8 bits wide. 

Register size:

All the general-purpose registers within the 8085 can store 8 bits of data. 

Arithmetic operations:

The arithmetic logic unit (ALU) in the 8085 is also designed to perform calculations on 8-bit data. 

8085 Microprocessor!

8085 is articulated as "eighty-eighty-five" chip. It is an 8-bit chip planned by Intel in 1977 utilizing NMOS innovation.

It has the accompanying arrangement -  

• 8-bit Data Bus 
• 16-bit address bus, which can address up to 64KB  
• A 16-bit program counter  
• A 16-bit stack pointer  
• Six 8-bit registers orchestrated in sets: BC, DE, HL  
• Requires +5V supply to work at 3.2 MHZ single stage clock  

It is utilized as a part of a microwave, washing machine, cell phones, and so forth.

8085 Microprocessor consists of 8-Bit  of Arithmetic Logic Unit. thus, it is called as 8-Bit Microprocessor.
