Key Features 

• Operating characteristics – Voltage range: 2.7 V to 5.5 V – Ambient temperature range: -40 °C to 105 °C for HSRUN, -40 °C to 125 °C for RUN 

• ARM™ Cortex-M4F/M0+ core, 32-bit CPU – Supports up to 112 MHz frequency (HSRUN) with 1.25 Dhrystone MIPS per MHz – ARM Core based on the ARMv7 Architecture and Thumb®-2 ISA – Integrated Digital Signal Processor (DSP) – Configurable Nested Vectored Interrupt Controller (NVIC) – Single Precision Floating Point Unit (FPU) 

• Clock interfaces – 4 - 40 MHz fast external oscillator (SOSC) – 48 MHz Fast Internal RC oscillator (FIRC) – 8 MHz Slow Internal RC oscillator (SIRC) – 128 kHz Low Power Oscillator (LPO) – Up to 112 MHz (HSRUN) System Phased Lock Loop (SPLL) – Up to 50 MHz DC external square wave input clock – Real Time Counter (RTC) 

• Power management – Low-power ARM Cortex-M4F/M0+ core with excellent energy efficiency – Power Management Controller (PMC) with multiple power modes: HSRUN, Run, Stop, VLPR, and VLPS – Supports peripheral specific clock gating. Only specific peripherals remain working in low power modes.
