Discussion Overview

The discussion centers on the interfacing of the 8086 microprocessor to a single 8-bit wide RAM module. Participants explore the connections required for the 8086's address and control pins, specifically A0, BHE, and A1-A19, in this context.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant asks how to connect the 8086's A0, BHE, and A1-A19 pins to a single 8-bit wide RAM.
  • Another participant suggests that the question is easily answered through online resources or Intel's documentation.
  • A different participant expresses difficulty in finding information specifically about interfacing a single bank of RAM, questioning how to connect A0 and BHE with only one RAM available.
  • One participant proposes that an 8088 might be more suitable than an 8086 for interfacing with an 8-bit data bus.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the interfacing method, with multiple viewpoints and uncertainties expressed regarding the connections and the suitability of the 8086 versus the 8088.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about the RAM configuration and the specific requirements for interfacing, which remain unresolved.

How to interface 8086 to a single 8 bit wide RAM (only one RAM is given)? How to connect 8086's A0, BHE, A1-A19 pins to the mentioned RAM?

What have you found so far? This is a very easy question to find an answer for by using Google, or even looking at Intel's website...
 
I only found the interfacing to low bank and high bank. I can't find anything about interfacing to a single bank. How do I connect both A0 and BHE when there's only one RAM available? Not two.
 
I would think you'd need an 8088 instead of an 8086 in order to get an 8 bit data bus.
