Low Voltage Stamps?

Greetings!

Anyone know if there's any plans for a low voltage BS chip?
2.5V to 3V would be grand...
(I'm working on a VERY small project, and batteries are taking up a lot of
space)

A step up DC-DC chip isn't the answer either because that means I have to
use batteries that can deliver double the Amperage. (I'm trying to make do
with 'button' size cells together with a BS1 )


Just wondering...

    We've had no discussions about building a low-voltage Stamp. I think, for
    the time being, that would not be a fruitful project for us. Despite
    appearances, we're very small and have limited resources. Right now our
    target is cross-platform compiler so that customers can program BASIC Stamps
    with nearly any OS they choose.

    The BS1 is based on a PIC16C56, which does not have a brownout
    detector built in. That chip is supposed to operate down to 3.0
    volts at 4mhz. I see no reason you could not make yourself an OEM
    BS1 to run at 3.0 volts. It would really get to micro power at that
    level. That was always a great feature of the BS1--low power
    operation.

    I have made BS2 circuits that run on a stack of two coin cells in one
    holder (6 volts). The circuit had a pushbutton to activate, then at
    the end of the action, the BS2 turned off its own power supply for
    zero-power standby.
