help: low power microcontroller chosen

[gzeds]

could you advise me about a 8 bit low power consumption microcontroller.

These are the other characteristics:

2 kB/4kB flash

real time clock

20 pin o similar...

Hi,

If you want to use a Freescale 8-bitter then you will need to use an external RTC say from Maxim/Dallas. Could interface using SPI or I2C.

Some application specific ones that are fairly big have an RTC but none of the general purpose ones do.

A QG8 might fit the bill, but only 16 pin (See under HCS08 menu, top left).
