–
System timer (SysTick), providing a simple, 24-bit clear-on-write, decrementing, wrap-on-zero
counter with a flexible control mechanism
Thumb®-compatible Thumb-2-only instruction set processor core for high code density
50-MHz operation
Hardware-division and single-cycle-multiplication
Integrated Nested Vectored Interrupt Controller (NVIC) providing deterministic interrupt
handling
30 interrupts with eight priority levels
Memory protection unit (MPU), providing a privileged mode for protected operating system
functionality
Unaligned data access, enabling data to be efficiently packed into memory
Atomic bit manipulation (bit-banding), delivering maximum memory utilization and streamlined
peripheral control
128 KB single-cycle flash
•

•
32 KB single-cycle SRAM
Four General-Purpose Timer Modules (GPTM), each of which provides two 16-bit
timer/counters. Each GPTM can be configured to operate independently as timers or event
counters as a single 32-bit timer, as one 32-bit Real-Time Clock (RTC) to event capture, or
for Pulse Width Modulation (PWM)

User-managed flash block protection on a 2-KB block basis
User-managed flash data programming
User-defined and managed flash-protection block
Programmable one-shot timer
Programmable periodic timer
Real-Time Clock when using an external 32.768-KHz clock as the input
User-enabled stalling in periodic and one-shot mode when the controller asserts the CPU
Halt flag during debug
General-purpose timer function with an 8-bit prescaler
