Extreme Low-Power
Multiple Power Management Options for Extreme Power Reduction:VBAT allows for lowest power consumption on backup battery (with or without RTCC)Deep Sleep allows near total power-down with the ability to wake-up on external triggersSleep and Idle modes selectively shut down peripherals and/or core for substantial power reduction and fast wake-upDoze mode allows CPU to run at a lower clock speed than peripheralsAlternate Clock modes allow On-the-Fly Switching to a Lower Clock Speed for Selective Power ReductionExtreme Low-Power Current Consumption for Deep Sleep WDT: 650 nA @ 2V typical RTCC: 650 nA @ 32 kHz, 2V typical Deep Sleep current, 60 nA typical160 uA/MHz in Run modeCPUModified Harvard ArchitectureUp to 16 MIPS Operation @ 32 MHz8 MHz Internal Oscillator: 96 MHz PLL option Multiple clock divide options Run-time self-calibration capability for maintaining better than ±0.20% accuracy Fast start-up17-Bit x 17-Bit Single-Cycle Hardware Fractional/Integer Multiplier32-Bit by 16-Bit Hardware Divider16 x 16-Bit Working Register ArrayC Compiler Optimized Instruction Set ArchitectureTwo Address Generation Units for Separate Read and Write Addressing of Data MemoryAnalog FeaturesDual Partition Flash with Live UpdateCapability
