Hi Everyone.
I am a noob to the MSP430 line... and I just picked up a few launchpad's. We chose the msp430g2231 for it's low power and small foot print and ADC lines. I want to put this microcontroller in to an existing product which has some op-amps and sensors connected to a 2.5V linear regulator and talk to an Ember chip. My question is I'd like to power the msp430 with 2.5V since the chip will use less power at that and it's available in the existing circuit... but, will I be able to use the internal 2.5V reference even though Vcc is 2.5V? Or would I have to connect the 2.5V to VREF+?
I guess I could use the internal 1.5V as well, right? Then some of my sensors may require a voltage divider.
thanks
Jeff
