10-bit ADC with input multiplexing among 8 pins.

10-bit DAC.

Four general purpose timers/counters with 8 capture inputs and 10 compare

outputs. Each timer block has an external count input.

Two PWM/timer blocks with support for three-phase motor control. Each PWM has

an external count inputs.

RTC with separate power domain, clock source can be the RTC oscillator or the

APB clock.

2 kB SRAM powered from the RTC power pin, allowing data to be stored when the

rest of the chip is powered off.

WatchDog Timer (WDT). The WDT can be clocked from the internal RC oscillator,

the RTC oscillator, or the APB clock.

Standard ARM test/debug interface for compatibility with existing tools.

Emulation trace module supports real-time trace.

Single 3.3 V power supply (3.0 V to 3.6 V).

Three reduced power modes: idle, sleep, and power-down.

Four external interrupt inputs configurable as edge/level sensitive. All pins on port 0

and port 2 can be used as edge sensitive interrupt sources.
