EFM32 Zero Gecko FamilyEFM32ZG Data SheetThe EFM32 Zero Gecko MCUs are the world’s most energy-friend-ly microcontrollers.The EFM32ZG offers unmatched performance and ultra low power consumption in bothactive and sleep modes. EFM32ZG devices consume as little as 0.5 μA in Stop modeand 114 μA/MHz in Run mode. It also features autonomous peripherals, high overall chipand analog integration, and the performance of the industry standard 32-bit ARM Cortex-M0 processor, making it perfect for battery-powered systems and systems with high-performance, low-energy requirements.EFM32ZG applications include the following:KEY FEATURES• ARM Cortex-M0 at 24 MHz• Ultra low power operation• 0.5 μA current in Stop (EM3), withbrown-out detection and RAM retention• 48 μA/MHz in EM1• 114 μA/MHz in Run mode (EM0)• Fast wake-up time of 2 µs• Hardware cryptography (AES)• Up to 32 kB of Flash and 4 kB of RAM• Energy, gas, water and smart metering• Health and fitness applications• Smart accessories• Alarm and security systems• Industrial and home automation32-bit busLowest power mode with peripheral operational:EM2 – Deep SleepEM1 - SleepEM4 - ShutoffEM0 - ActiveEM3 - StopCore / MemoryFlash ProgramMemoryDebug InterfaceARM CortexTM M0 processorRAM MemoryDMA ControllerSecurityHardware AESEnergy ManagementPower-onResetVoltageRegulatorVoltageComparatorBrown-outDetectorClock ManagementHigh FrequencyRC OscillatorLow FrequencyCrystal OscillatorLow Freq.RC OscillatorAuxiliary HighFreq.
