6.2 Power Management Unit
The Integrated Power Management Unit (PMU) supplies internal analog modules,
internal digital logic, memories and pads. It also provides regulated voltages for the
contactless and the contact interfaces. The PMU automatically adjusts the internal
regulators to minimize the power consumption during all possible power modes. The
power management unit embeds also mechanisms to prevent the IC from overheat,
current overconsumption and overloading the DC-to-DC converter. For the RF
transmitter stage, a separated low-drop output regulator is embedded. This module also
integrates a temperature sensor and Power On Reset generator. The PMU is made of
analog modules and digital control unit embedding the registers
