Integrated Nested Vectored Interrupt Controller (NVIC) providing deterministic interrupt
handling
42 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
256 KB single-cycle flash
•
•
•
64 KB single-cycle SRAM
Four General-Purpose Timer Modules (GPTM), each of which provides two 16-bit timers.
Each GPTM can be configured to operate independently:
•
•
•
•
32-bit Timer modes
•
•
•
•
•
16-bit Timer modes

•
User-managed flash block protection on a 2-KB block basis
User-managed flash data programming
User-defined and managed flash-protection block
As a single 32-bit timer
As one 32-bit Real-Time Clock (RTC) to event capture
For Pulse Width Modulation (PWM)
To trigger analog-to-digital conversions
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
ADC event trigger
General-purpose timer function with an 8-bit prescaler
Programmable one-shot timer
