[ts-7000] REAL TIME CLK

[joel garner <>]

Hi All,

 

why do we have such a bulky REAL TIME CLK on the 7250 BOARD?

can't we do our task with a smaller chip...somethink similar to one in a cellphone..

 

and where does the chip gets its power from.. do i need a battery on the dev. board so that the RTC can function and show me the right time when i switch it on...

 

Chill,

Joel.
