Unraveling 8051 and the MCU
« on: May 07, 2009, 07:54:41 PM »
Are those AVR MCU's you guys use (like the ATMega8) etc 8051 devices(or compatible)?

A microcontroller i found has:
5v Operation
3.5MHz to 40MHz
Three 16-bit Timer/Counters
256 Bytes of on-chip data RAM
64 Kbytes on-chip Flash memory
32 Programmable I/O lines
6 interrupt Sources
Four 8-bit I/O ports
Full-duplex enhanced UART compatible with the standard 80C51 and the 80C52


Is there any other criteria a chip needs to be used in hobby robotics?

8051's are different architecture for same thing (loosely) they use a different instruction set than the AVR's and various other types of MCU. They were started by Intel.

Just to close this out so someone else doesn't have to spend as long figuring it out.

some atmel mcu's use 8051 architecture.....    I tjink most of atmel avr range are based on modified harvard architechture but there are definately some based around intel 8051
