substituted for the RC oscillator under software control. In normal operation the RTC is
always powered up, even in the Power up state.
The dc_dc_cntl programmable counter is 48-bits and provides up to 272 years worth of
standby duration.
For the other RTC_IO pins, the programmable embedded counters (32-bit) are provided to
enable periodic wake-up of the remainder of the external system, and provide a 1.5 days
max period. The RTC_IO pins can be configured as inputs (ALARMS) or output (WAKE
UP) pins.
The RTC includes a Power-On Reset (POR) circuit, to eliminate the need for an external
component. The RTC contains low-leakage non-volatile (battery-powered) RAM, to enable
storage of data that needs to be preserved. It also includes a brown-out detector that can be
disabled by SW.
Total current consumption of the RTC is typically less than 5 μA with 1Kbyte of data
storage, using the 32.768 kHz oscillator.
