How is the 8085 microprocessor different from the previous 8 series microprocessors?..

Answer / Shailendra Kumar Dwivedi

The Intel 8085 microprocessor was an improvement over the earlier 8080 microprocessor with several key differences:
1. Increased Speed: The 8085 operated at a higher clock speed (6 MHz) compared to the 8080 (2 MHz).
2. Built-in Interrupts: The 8085 had built-in hardware interrupt handling, while the 8080 required software interrupts.
3. Increased Memory Addressing: The 8085 could address up to 64 KB of memory, compared to the 8080's 16 KB.
4. Direct Memory Access (DMA): The 8085 had a DMA channel for transferring data between I/O devices and memory without CPU intervention.
