8-Bit Architecture

Hello All,

My doubt is whether all 8-bit freescale microcontrollers are having Von Neumann architecture.

Hello Thunder,

AFAIK all 8-bit MCUs from Freescale are CISC and Von Neumann devices.

Best,

Hello thunderbolt,

Which devices in particular are causing this doubt?
Given that there is only two cores in current use (HC08 and S08) I fail to see where it may be coming from.

Hello Peg,

I am preparing for a seminar on Freescale architecture,and I came across different cores like

S08, RS08 ,HC08,HC11 etc .When I read different documents ,I could find that all are VonNeumann .But for others like PIC ,ATMEL there are 8-bit controllers with Harvard architecture.So to clarify the doubts only I posted this.

So the conclusion is like all are VonNeumann architecture.
