I have been working with the AT89C2051 for a while, but the problem with it is that the memory is limited, and it requires special logic functions to program it.
What I would like to do is store the code on the ROM chip, so that when it is connected to the microcontroller, the microcontroller executes the code on the rom chip starting at address 0 (beginning of the chip).
I don't want a chip that shares an address and data line together like the intel 8088.
The 8051 chips seem to be more my style, but I need advice.
So to sum up, this is what I want to achieve:
#1. Transfer code from my computer to the ROM chip
#2. Connect the ROM chip to a microcontroller
#3. Connect the HD47780 compatible LCD to the microcontroller's output pins
#4. Run ROM code when circuit is turned on.
I'm looking for a low-cost microcontroller that satisfies this.
