BS2e Max. Current Consumption

hmlittle59

Hello All,

I'm trying to calculate the Max. Power consumption I will use and the voltage regulator needed. I have all the Data Sheets for the parts I'm using (DS1302,shift register, BackLight Display...etc) that show ratings, but I could not find Current Consumption on the 20 MHz SMT part and the BS2e(Interpreter)SMT. The BS2e would be the main one needed. I've purchased a 5vdc 1.5a SMT regulator which appears to be way over the rule of thumb double the amounted needed....Anyway

1) I can not find the Max. Current of the BS2e?
2) 20 MHz Resonator...Is there much current draw at all???

thanks all

The Basic Stamp comparison chart gives the current consumption: www.parallax.com/tabid/436/Default.aspx

The actual current drawn depends a lot on what's connected to the Stamp, but this is a good starting point.

The resonator does not draw power by itself. It uses energy supplied by the Stamp's oscillator to work.

thanks Mike,

I was trying to get it for the interpreter itself(I mixed up what I was asking for...My bad) but I will use these figures and see what I come up with. So far its 505 mA (max.). (8 I/O x 60 mA + 25 mA).

thanks again
