Internet of Things (IoT) art microcontrollers, sensors and wireless connectivity solutions, a leading provider of Silicon Labs (Silicon Technology Co., Ltd.) today announced the industry's most energy-efficient USB microcontroller (MCU). The new Happy Gecko MCU Silicon Labs is an award-winning EFM32® 32 位 newest member of the MCU product family offers the industry's lowest USB power, enabling longer battery life and energy harvesting applications. ARM®Cortex®-M0 + core and low-power peripherals, Happy Gecko family of products for all types of IoT applications simplify USB connection design based on these applications include: smart meters, intelligent home and building automation, alarm and security systems, smart accessories and Wear equipment.

As a USB bridge chip and intelligent interface IC leading supplier, Silicon Labs Happy Gecko develop products to meet customer demand for low-cost, low-power USB connectivity solutions growing. With more than 3 billion annually USB device shipments, USB has become the fastest growing consumer applications interfaces, and also gain the favor of industrial automation. IoT In today's world, developers have found a portable battery-powered devices can be connected to add USB connection may lead to the application of a double current consumption. Silicon Labs' Happy Gecko MCU for these power-sensitive IoT applications provide an ideal energy-efficient USB connectivity solution.

Happy Gecko USB MCU with advanced energy management system, with five power consumption mode, by spending as little time in work mode, so that the application can be maintained at optimum energy state. In deep sleep mode, Happy Gecko MCU has industry-leading 0.9μA standby current consumption (and at the same time be able to enable 32.768kHz RTC, keep the RAM / CPU Enable the brownout detection and power-on reset circuit). 24MHz operating speed of execution when the actual code (prime number search algorithms), operating mode, power consumption can be lowered to 130μA / MHz. In addition, USB MCU can wake-up with a standby time of 2μs further reduce power consumption.

Like all EFM32 MCU Like, Happy Gecko products also include peripheral reflex system (Peripheral Reflex System, PRS) feature, which greatly improved the energy efficiency of the overall system. 6-channel PRS can monitor complex system-level events, allowing autonomous communication between different MCU peripherals, without CPU involvement. PRS can wake up the CPU before to capture a specific event occurs, it can be maintained as long Cortex-M0 + core in a power saving standby mode to reduce system power consumption and extend battery life.

EFM32 popular with many low-power chip precision analog peripherals, Happy Gecko MCU also have the same characteristics. These low-power peripherals include an analog comparator, the power supply voltage comparator, on-chip temperature sensor, programmable current DAC (IDAC), and the conditions at 1MHz sampling rate while consuming only 350μA current 12-bit analog to digital converter (ADC ). The on-chip AES encryption provides security for IoT applications such as smart meters and wireless sensor networks, wireless connectivity deployments.

Happy Gecko series outstanding single chip (single-die) integration feature enables developers to reduce the number of chip devices and materials (BOM) cost. Although typical USB connectivity solutions such as chip devices typically require crystal and other regulators, but highly integrated Happy Gecko MCU by having a full-speed USB PHY, on-chip-free crystal structure of the regulator and the resistor cut almost all of these separate devices. Happy Gecko MCU supports space-saving QFN, QFP and chip scale package (CSP) options, small package size is sufficient for the USB connector and slim profile wearable designs.

Silicon Labs vice president and general manager, MCU and wireless products introduced Daniel Cooley: "Happy Gecko MCU for developers to bring many benefits to Silicon Labs EFM32 energy-efficient architecture for adding USB in their battery-powered applications offer the coveted IoT connection Cheap plug and play solution .Happy Gecko USB MCU and Simplicity Studio development environment we provide combined, making the system designers to lowest energy consumption and lowest cost BOM their 32-bit applications to connect to almost any device. "

Simplify USB Development

Silicon Labs' Simplicity Studio development platform to support Happy Gecko products to help developers simplify low-power design. Simplicity Energy Profiler enables real-time energy configuration and code debugging. Simplicity Battery Estimator through the use of application configuration, consumption patterns and peripherals, calculate the expected battery life. Simplicity Configurator provides an intuitive interface to MCU pin configuration, and can automatically generate initialization code. Development code provides for other EFM32 MCU can be reused for Happy Gecko applications. Developers can download for free from the website www.silabs.com/simplicity-studio Simplicity Studio, and use USB software source code and examples of Silicon Labs.

Happy Gecko series products have been ARM® mbed ™ ecosystem support this ecosystem includes Silicon Labs and ARM development of new power management API, it can help developers quickly realize the transformation from design concept to final product. Low power mbed API designed with low power consumption scenarios, energy consumption can be limited IoT design for rapid prototyping. On EFM32 MCU of ARM mbed API can be based on the use of peripherals automatically optimize sleep mode, greatly reduces system-level power consumption. Happy Gecko Starter Kit directly support the ARM mbed. Silicon Labs also introduced a mbed API to support Leopard, Giant, Wonder and Zero Gecko MCU.
