Which microcontroller?

I am making a small project that will require a microcontroller  It
does not have to be powerful.  IE 1 MHZ would be fine.  I want one that
has built in a real time clock.  IE time and date. EE proms, and A-D.  I
looked at the PIC ones and i did not find one with a clock.  I know that
one could make program and use the onboard timer. The timmer must be
accurate.
        Any Suggestions?

HELP: H8/300H dev tools info

I’m about to start a microcontroller project and the H8/300H series from
Hitachi seems to fit the bill, especially the 3002 because of its 2 serial
ports.

Does anyone know how much the C-ompilers, Assemblers, In-Ciruit emualtors
and evaluation boards cost? I’ve read about Hitachis on their US weeb
page, but they dont give prices. I’m in the UK so suppliers and prices in
the UK would be great thanks!

Any info ASAP much appreciated.
