Background
Some of my sketches or ideas require a common data buss to all perph chips.
The issue
This way issue still lays before me, how then, if I am going for a common data buss. how do I address each chip via this microcontroller?
However, Using a microprocessor is a plus in that direction, but i rather not design something that takes more chips when i can just handle with one central chip to work out the calculations and decisions.
Main idea
My question is. What is a good microcontroller that offers me
- 16 bit parallel ports.
- easy adressing to perph chips
- able to handle a wide variety of brands.
Documents and data sheets that are related
Here are some related documents that I intended to use.
8bit Atmel Atmega640 microcontroller
HS cmos ARING bus interface 16bit
AD5207 2 channel 256 position digital potentiometer
RIRWE416D4 series 4M high speed SRAM 256kbit × 16 bit
Finding a good microcontroller will be a step into finding a good 16 ADC.
Why this question
The intersil 80cxx platform is cringe worthy in my view because, the address and the data is share a common pin set and I need extra hardware to demux the data and the address. Also, the platform they give is byte oriented I need word.
Replacement requirements.
I need something that gives me good high speed performance that I can use in a microcomputer esk layout.
My number one priority is finding something that is highly customizable with the requirement that I can use the standard 15 pin serial com ports or at least
The parallax propellor 8 core is close could go down to two core.
