automatically. The RTC provides a programmable alarm and programmable periodic
interrupts with wakeup from Stop and Standby modes.

The RTC can be calibrated with an external 512 Hz output, and a digital compensation
circuit helps reduce drift due to crystal deviation.
There are twenty 32-bit backup registers provided to store 80 bytes of user application data.
They are cleared in case of tamper detection.
GPIOs (general-purpose inputs/outputs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the
GPIO pins are shared with digital or analog alternate functions, and can be individually
remapped using dedicated AFIO registers. All GPIOs are high-current-capable except for
analog pins. The alternate function configuration of I/Os can be locked if needed following a
specific sequence in order to avoid spurious writing to the I/O registers. The I/O controller is
connected to the AHB with a toggling speed of up to 16 MHz.
External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 23 edge detector lines used to generate
interrupt/event requests. Each line can be individually configured to select the trigger event
(rising edge, falling edge, both) and can be masked independently. A pending register
maintains the status of the interrupt requests. The EXTI can detect an external line with a
pulse width shorter than the Internal APB2 clock period. Up to 83 GPIOs can be connected
to the 16 external interrupt lines.
The programmable wakeup time ranges from 120 µs to 36 hours
Stop mode consumption with LSI and Auto-wakeup: 1.2 µA (at 1.8 V) and 1.4 µA (at
3.0 V)
Stop mode consumption with LSE, calendar and Auto-wakeup: 1.3 µA (at 1.8V), 1.6 µA
(at 3.0 V)
