• Standby Mode, mix of Idle and Backup Mode, peripheral running at low frequency, processor
• Backup Mode, Main Power Supplies off, VDDBU powered by a battery
• Includes a 20-bit Periodic Counter, with less than 1 µs accuracy
• Includes a 12-bit Interval Overlay Counter
• Real Time OS or Linux
• 16-bit key-protected only-once-Programmable Counter
• Windowed, prevents the processor to be in a dead-lock on the watchdog access
• Real-Time Timer, allowing backup of time with different accuracies
• Low power consumption
• Full asynchronous design
stopped waiting for an interrupt
– 32-bit Free-running back-up Counter
– Integrates a 16-bit programmable prescaler running on slow clock
– Alarm Register capable to generate a wake-up of the system through the Shut Down
