Here are some key features and characteristics of the Intel 8085:
1.)Architecture:
- The 8085 microprocessor has an 8-bit architecture, meaning it processes data in 8-bit chunks.
- It has a 16-bit address bus, allowing it to address up to 64 KB of memory.
2.)Register:
- The 8085 has various registers, including:
- Accumulator (A): Used for arithmetic and logic operations.
- General-purpose registers (B, C, D, E, H, L): Used for various data manipulation tasks.
- Stack Pointer (SP): Manages the stack operations.
- Program Counter (PC): Keeps track of the address of the next instruction to be executed.
3.) Instruction Set:
- The instruction set of the 8085 is designed to perform a wide range of operations, including arithmetic, logic, data transfer, and control flow.
- Instructions are encoded as 8-bit or 16-bit binary codes.
4.) Clock Speed:
- The 8085 typically operates at clock speeds ranging from 3 to 6 MHz.
5.) Memory Addressing:
- With its 16-bit address bus, the 8085 can address a maximum of 64 KB of memory.
- It supports both ROM (Read-Only Memory) and RAM (Random Access Memory).
6.) Input/Output:
- The 8085 includes instructions and hardware support for input and output operations, allowing it to communicate with external devices.
7.) Interrupts:
- The 8085 supports interrupts, allowing external devices to request the CPU’s attention during certain events.
8.) Power Supply:
- The 8085 typically operates on a +5V power supply.
9.) Buss Structure:
- The 8085 has a multiplexed address and data bus, meaning the same set of lines is used for both address and data transfer.
- It has control signals to manage various operations, including data transfer, memory read/write, and interrupt handling.
10.) Application:
- The 8085 found applications in various fields, including early personal computers, educational environments, and industrial control systems.
11.) Legacy:
- While the 8085 is an older microprocessor, its legacy and influence are still felt in the field of computer architecture and microprocessor design.
