Said to be the industry's most energy friendly USB enabled MCUs, the Happy Gecko range from Silicon Labs is designed to deliver longer battery life and support energy harvesting.
Based on the ARM Cortex-M0+ core and featuring low energy peripherals, the Happy Gecko has been developed to address rising demand for cost effective, low power USB connectivity solutions.
The MCUs, which consume 0.9µA in stand by, draw 130µA/MHz at 24MHz and are said to wake up from stand by in 2µs. Also featured is the six channel Peripheral Reflex System, which enhances overall energy efficiency. This monitors system level events and allows different MCU peripherals to communicate with each other autonomously.
Other peripherals include an analogue comparator, supply voltage comparator, on-chip temperature sensor, programmable current D/A converter and a 12bit A/D converter.
"Happy Gecko MCUs bring the benefits of Silicon Labs' EFM32 architecture to developers seeking an economical, plug and play solution for adding USB connectivity to their battery powered IoT applications," said Daniel Cooley, general manager of Silicon Labs' MCU and wireless products.
