The 6504 Datasheet is a critical document for anyone interested in retro computing, electronics, or the history of personal computers. This datasheet provides all the essential information about the 6504 microprocessor, a simplified version of the more famous 6502, detailing its architecture, pinouts, electrical characteristics, and instruction set. Understanding the 6504 Datasheet is key to understanding how early computer systems functioned.
Decoding the 6504 Datasheet Technicalities
A datasheet, such as the 6504 Datasheet, is essentially a technical manual provided by the chip manufacturer. It’s designed to give engineers and hobbyists all the information they need to properly integrate the chip into a circuit. In the case of the 6504, the datasheet covers a variety of key aspects, including:
- Pin Configuration: Showing which pin does what.
- Electrical Characteristics: Detailing voltage, current, and timing specifications.
- Instruction Set: Explaining all the commands the processor can execute.
The 6504 Datasheet is used in several critical ways. Firstly, it helps hardware designers to understand how to connect the 6504 to other components in a system, such as memory chips, input/output devices, and clock circuits. Secondly, software developers use the information about the instruction set to write programs that run on the 6504. Thirdly, it serves as a troubleshooting guide when problems arise in a 6504-based system. Ultimately, without the 6504 Datasheet, it would be virtually impossible to design, build, or program systems using this processor.
The 6504, while similar to the 6502, has some key differences that are clearly outlined in its datasheet. Notably, it only has a 13-bit address bus compared to the 6502’s 16-bit address bus. This limitation reduces the amount of directly addressable memory from 64KB to 8KB. Understanding these differences is crucial for designing systems that work properly with the 6504.
| Feature | 6502 | 6504 |
|---|---|---|
| Address Bus | 16-bit | 13-bit |
| Maximum Memory | 64KB | 8KB |
