at89s52 power usage
Hi,
I have been prototyping a small project of mine based on the AT89S52 for sometime now. Now as I am nearing completion I am thinking of the power consumption issues I might have with the finished stuff, which will run on battery power.
Till now, I was prototyping using an evaluation board which runs on a 5 VDC power supply. So I did not have any power consumption issues.
However, in a few days time when I would be creating a battery powered version
of my project, how will it be w.r.t the power consumption?? Any prior experience from any one of you folks out here?
I am planning to use 4x1.5 VDC cells in series to get about 6 Volts. My project runs an RTC and an LCD. Basically it is a digital clock based on the 89S52 micro.
I was also thinking of adding a temperature display based on the DS18S20 temperature sensor. Will it be overkill?
If anyone in EDABOARD has the experience of using AT89S52 for battery powered applications before, then I would be grateful to know how it performs w.r.t power consumption.

Seemanta
P.S. I searched in ATMEL website and discovered that there is a AT89LP series which offer single cycle execution and low power, but after making some enquiries I realized that unfortunately LP series is not available in India(Hyderabad) till now. Duh!
