Core
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. The GPIO pins can be used as alternative functional pins by configuring the corresponding registers regardless of the input or output pins. The external interrupts on the GPIO pins of the device have related control and configuration registers in the External Interrupt Control Unit, EXTI.
