Question

Write features of 8085 Microprocessor.

Answer 1

The main features of the 8085 microprocessor are given below:

1. Intel’s 8085 is an 8-bit microprocessor, which means it has an 8-bit data bus and can transfer 1 byte of data at a time.
2. The 8085 is available in a 40-pin plastic or ceramic DIP package.
3. It has a 16-bit address bus, allowing it to access up to 64 KB of physical memory.
4. The address bus is split into two parts: the lower 8 address lines are multiplexed with the data bus, while the higher-order address lines are carried on separate lines.
5. For selecting external memory or I/O devices, the 8085 uses an I/O-mapped I/O scheme.
6. Communication with external devices is carried out using the interrupt method (hardware interrupts).
7. The microprocessor operates on a single +5V power supply and works with a 3 MHz single-phase clock.
