Functional overview

The RTC is an independent BCD timer/counter. It supports the following features:

• Calendar with subsecond, seconds, minutes, hours (12 or 24 format), week day, date,

month, year, in BCD (binary-coded decimal) format.

• Automatic correction for 28, 29 (leap year), 30, and 31 days of the month.

• Two programmable alarms with wake up from Stop and Standby mode capability.

• On-the-fly correction from 1 to 32767 RTC clock pulses. This can be used to

synchronize it with a master clock.

• Digital calibration circuit with 1 ppm resolution, to compensate for quartz crystal

inaccuracy.

• Two anti-tamper detection pins with programmable filter. The MCU can be woken up

from Stop and Standby modes on tamper event detection.

• Timestamp feature which can be used to save the calendar content. This function can

be triggered by an event on the timestamp pin, or by a tamper event. The MCU can be

woken up from Stop and Standby modes on timestamp event detection.

• 17-bit Auto-reload counter for periodic interrupt with wakeup from STOP/STANDBY

capability.

The RTC clock sources can be:

• A 32.768 kHz external crystal

• A resonator or oscillator

• The internal low-power RC oscillator (typical frequency of 40 kHz)

• The high-speed external clock divided by 32.
