Need Advice please: microcontroller with RS-232 Output

The 8051/2 architecture was very popular in the Smartcard/cell phone SIM market. There were other contenders such as the Motorola HC08. There are other processors as well but PICs did not feature. The 8051/2 might therefor still be the overall micro volume leader.

?? Could have fooled me. New devices all the time. They're like roaches. Want a 100MIPS 8-bit processor with 12-bit ADC or an on-board

24-bit delta-sigma? Where's my PIC, dude?

Microchip should be able to carry their success in the low end (12-bit instruction core) and their concentration (only one supplier as opposed to a couple of dozen for the 8051 core) and their broad base (lots of small companies and developers) to their 18 series and maybe the dsPIC/24F, at least enough to make some good profits, but very high volume will probably remain elusive.

Microchip has been doing some interesting business in low-end "untested" parts for noncritical applications.

Atmel make one heck of a lot of AT89 flash 8051s. They are very popular in Asia.

I mostly see 6805 and 8051s in 8-bit processor smart cards.

BUT:

---> ARM is the new 8051

An Atmel ATmega8 should do trick. Plenty of software on:
