[1] For reliable oscillator start-up at power on use V
DD
greater than 1.3 V. If powered up at 1.0 V the oscillator will start but it might be a bit
slow, especially if at high temperature. Normally the power supply is not 1.0 V at start up and only comes at the end of battery discharge.
V

min of 1.0 V is specified so that the customer can calculate how large a battery or capacitor they need for their application. V
