Notes:
(a) Production testing of the device is performed at 25°C. Functional operation of the device and parameters specified from -40°C to +125°C are
guaranteed by design, characterization and process control.
(b) Between 1.2V and 2.2V the device will run in the Low Voltage Startup Mode (for details refer to section "Low Voltage Operation")
