Silicon Labs, a provider of microcontroller, sensing and wireless connectivity solutions for the Internet of Things (IoT), has released a new line of energy-friendly USB-enabled microcontrollers (MCUs). This latest addition to Silicon Labs’ EFM32 32-bit MCU portfolio, the new Happy Gecko MCUs are designed to deliver the lowest USB power drain in the industry, enabling longer battery life and energy harvesting applications.
Based on the ARM Cortex-M0+ core and low-energy peripherals, the Happy Gecko family simplifies USB connectivity for a wide range of IoT applications including smart metering, home and building automation, alarm and security systems, smart accessories and wearable devices.
Happy Gecko USB MCUs feature an advanced energy management system with five energy modes enabling applications to remain in an energy-optimal state by spending as little time as possible in active mode. In deep-sleep mode, Happy Gecko MCUs have an industry-leading 0.9 μA standby current consumption (with a 32.768 kHz RTC, RAM/CPU state retention, brown-out detector and power-on-reset circuitry active). Active-mode power consumption drops down to 130 µA/MHz at 24 MHz with real-world code (prime number algorithm). The USB MCUs further reduce power consumption with a 2-microsecond wakeup time from standby mode.
