Well, ok but the little mcu I'm thinking of will run at 8 mips,
needs no xtal, has 16 i/o lines, has an 8 chan 10 bit a/d,
2 high speed pwm channels, timers, power supply monitoring,
is a 20 pin dip, costs $1.50,
can be programmed "in situ", and will support high level
language!



Sounds cool. Is that price for Qty 1? Got a part number?

Hi Roy,

This particular one is an Atmel ATTINY26, 1pc $2.58 from
Digi-Key. Much less in quantity from more major suppliers.
Atmel has a large family of these things in 8 pin to 64
pin packages, with internal flash memory from 1 to 128k.
They call them "AVR" RISC controllers. Atmel provides free
development software, really cheap development and programming
hardware, and freeware "C" compiler suites are available that
support the devices and the programmers. These things are
much faster while requiring less power than 8031 products.
They can be programmed "in system" so the devices do not need
to be socketed to allow program development or upgrading.
Check them out at www.atmel.com
