Question

Following statements are given in reference to 8085 Microprocessor:
(A) Its memory size is 64 KB
(B) It is a 40-pin IC
(C) Its clock frequency lies between 3 to 5 MHz
(D) It has 16 bit of each data and address lines.
Choose the correct answer from the options given below:

• A. (A), (B) and (D) only
• B. (A), (B) and (C) only
• C. (A), (B), (C) and (D)
• D. (B), (C) and (D) only

Hint:

The 8085 microprocessor has a 40-pin configuration, a clock frequency range of 3-5 MHz, and a 16-bit address bus but an 8-bit data bus.

Answer 1

The Correct Option is C

The 8085 microprocessor is a 40-pin Integrated Circuit (IC) and has a memory size of 64 KB. Its clock frequency typically ranges from 3 to 5 MHz, which was common for microprocessors of that era. However, the 8085 has an 8-bit data bus and a 16-bit address bus, not a 16-bit data and address bus as stated in option (D). Therefore, option (D) is incorrect.
Final Answer: \[ \boxed{\text{(3) (A), (B), (C) and (D)}} \]
