Re: microcontroller selection

Hi, I want to select a 8 bit microcontroller which can be run under 3V

Strange criteria indeed. Both data width and clock speed are usually determined by processing requirements, cost of goods requirements, development system cost, peripheral requirements, etc., etc. They are rarely independant variables.

Still, perhaps you've got 10000 12 MHz crystals in the junkbox and need to use your fingers to program in hex. If that's the case, various 8051's (from 6 to upwards of 100 pins - more if a core inside an FPGA) can run from a 12 MHz clock, some just under 1 MIPS some just under to 100 MIPS (spooky eh?).

Smells of USB?

Or an unlooper.
