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.

The propeller core is flexible to allow 16 bit ports and SPI, I2C or any data buss nterfacing protocol. Without the need for interrupts.
