automatically. The RTC provides a programmable alarm and programmable periodic
interrupts with wakeup from Stop and Standby modes.
The programmable wakeup time ranges from 120 s to 36 hours
Stop mode consumption with LSI and Auto-wakeup: 1.2 A (at 1.8 V) and 1.4 A (at
3.0 V)
Stop mode consumption with LSE, calendar and Auto-wakeup: 1.3 A (at 1.8V), 1.6 A
(at 3.0 V)
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.
