Factory programming of a customer secret key is available upon request. The microcontroller runs within a wide 1.7V to 3.6V operating range. For the ultimate in low-power performance, an ultra-lowpower stop mode 300nA typ is available. In this mode, only a minimum amount of circuitry is powered to support detection of the start of a 1-Wire transaction. When 1-Wire activity is detected, the microcontroller is turned on and the command is executed in an atomic fashion. This allows for stateless operation between commands, providing the highest reliability and lowest power consumption.
