32-bit Arm® Cortex®-M3 processor core
Up to 96 MHz operating frequency
Single-cycle multiplication and hardware division
Integrated Nested Vectored Interrupt Controller (NVIC)
24-bit SysTick timer
The Cortex®-M3 processor is a general-purpose 32-bit processor core especially suitable for products requiring high performance and low power consumption microcontrollers. It offers many special features such as a Thumb-2 instruction set, hardware divider, low latency interrupt respond time, atomic bit-banding access and multiple buses for simultaneous accesses. The Cortex®-M3 processor is based on the ARMv7 architecture and supports both Thumb and Thumb-2 instruction sets.

I/O Ports — GPIO

Up to 51 GPIOs
Port A, B, C, D are mapped as 16 external interrupts – EXTI
Almost I/O pins are configurable output driving current
There are up to 80 General Purpose I/O pins, GPIO, named from PA0 ~ PA15 to PE0 ~ PE15 for the implementation of logic input/output functions. Each of the GPIO ports has a series of related control and configuration registers to maximize flexibility and to meet the requirements of a wide range of applications. The GPIO ports are pin-hared with other alternative functions to obtain maximum functional flexibility on the package pins.

Power Management — PWRCU

Single VDD power supply: 2.0 V to 3.6 V
Integrated 1.5V LDO regulator for CPU core, peripherals and memories power supply
VBAT battery power supply for RTC and backup registers
Three power domains: VDD, 1.5 V and Backup
Four power saving modes: Sleep, Deep-Sleep1, Deep-Sleep2, Power-Down
