Could interface using SPI or I2C.</P><P>Some application specific ones that are fairly big have an RTC but none of the general purpose ones do.</P><P>A QG8 might fit the bill, but only 16 pin (See under HCS08 menu, top left).</P><P>Regards David</P><P>&nbsp;</P></BODY></HTML> Sun, 23 Jul 2006 05:55:39 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/help-low-power-microcontroller-chosen/m-p/124687#M409 peg 2006-07-23T05:55:39Z
