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.\ ## Further, you can visit on to the link for verification: 8085 Microprocessor **\** ![Why 8085 processor is called 8 bit processor?](https://answers.mindstick.com/questionanswer/2151e5f3-0333-4b5d-8c93-42d41d858eee/images/11b728d0-16f3-42b3-9dd7-dea60d3b76aa.png)**\** ## Cheers! ### Answer by Anubhav Sharma 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. ![Why 8085 processor is called 8 bit processor?](https://answers.mindstick.com/questionanswer/2151e5f3-0333-4b5d-8c93-42d41d858eee/images/e1916416-e6b4-4b4a-b2da-4e5b5fc1c5b0.jpg) --- Original Source: https://answers.mindstick.com/qa/31598/why-8085-processor-is-called-8-bit-processor Copyright © MindStick Software Pvt.
