The Motorola 6800 microprocessor, introduced in 1974, is an early microprocessor that has influenced many other designs in its architecture and functionality. Here are its key specifications:
### Key Specifications:
1. **Architecture**
- 8-bit microprocessor
- 16-bit address bus that allows access to 64 KB of memory
2. **Data Width**
- 8 bits (it processes data in 8-bit chunks)
3. **Instruction Set**
- Uses a simple instruction set with around 56 instructions, supporting various addressing modes including:
- Immediate
- Direct
- Indirect
- Register
- Indexed
4. **Registers**
- 3 general-purpose registers (A, B) of 8 bits each for data manipulation
- 1 16-bit program counter (PC)
- 1 16-bit stack pointer (SP)
- 1 status register (SR) including flags such as carry, zero, interrupt disable, etc.
5. **Clock Speed**
- Typically operates at clock speeds ranging from 0.5 MHz to 1 MHz
6. **Power Supply**
- Requires a power supply of approximately +5 volts
7. **Packaging**
- Available in a 40-pin dual in-line package (DIP)
8. **Bus Interface**
- 8-bit data bus
- 16-bit address bus for memory addressing
9. **Interrupts**
- Supports hardware interrupts allowing for real-time processing
10. **Memory Management**
- Uses an external memory system since it does not have built-in memory.
11. **Development Tools**
- Typically used with assemblers, debuggers, and emulators for software development.
The Motorola 6800 was widely used in early home computers, embedded systems, and various consumer electronics, laying the groundwork for future microprocessors, including those in the Motorola 680x0 family.
