Silicon Labs today announced the introduction of the industry-based 32-bit microcontroller (MCU) based on ARM® Cortex®-M0 + processor. EFM32TM Zero Gecko MCU Series Product Design Designed to achieve low system power consumption, such as portable health and fitness products, smart trackers, smart meters, safety systems, and wireless sensor nodes, and Collect the system-powered battery-powered battery system. The new Zero Gecko series products are the latest members of Energy Micro Pioneering EFM32 Gecko product portfolio. This series of products includes 16 cost-effective MCU products, which are redesigned for the help of connectable devices in the Internet (IoT) to achieve as low as possible.
The EFM32 Zero Gecko MCU has the most mature energy management system in the industry, which includes five energy modes, which makes the application to keep in the best energy mode, while the time spent as short-eddy time is more power consumption. In deep sleep mode, Zero Gecko MCU has industry-leading 0.9μA standby current consumption, and can maintain 32.768 kHz RTC, RAM / CPU status maintenance, power-down detection, and power-down reset circuits at the same time. Perform actual code (rigor search algorithm) from Flash from Flash, and the operating mode power consumption is reduced to 110μA / MHz. When the power is powered down, the current consumption is less than 20na. In addition, the EFM32 MCU has 2μs standby mode wake-up time, further reduces power consumption.
Like all EFM32 Gecko products, Zero Gecko MCU also includes the best energy-saving feature called Peripheral Reaction System (PRS), which significantly enhances system-level energy efficiency. PRS monitors complex system-level events and allows communication between different MCU peripherals to communicate directly, without CPU participation. With the PRS, the EFM32 MCU can monitor a series of specific events before waking up the CPU, maintaining the Cortex-M0 + processor cores that can make long-saving standby mode, reduce overall system power consumption.
EFM32 Zero Gecko MCU has many of the Silicon Labs popular TINY Gecko, Giant Gecko, Wonder Gecko, which is the same low, extends. These low-power outer peripherals include an analog comparator, a power supply voltage comparator, a chip temperature sensor, and a 12-bit analog-to-digital converter (ADC) that consumes only 350μA current at 1 MHz sample rate.
The EFM32 Zero Gecko device is a Cotex-M0 + M0 + M0 + MCU that uniquely integrated programmable current count converter (IDAC) on the market. This piece of precise analog IDAC can generate bias current from 0.05-64μA range, and only 10na consumption. IDAC provides accurate biasing and / or control capabilities for matching ICs and other external circuits, including amplifier / sensor / Whellbia and resistor trapezoidal circuitry, so that you can save high-cost slices for many cost-sensitive applications. External power amplifier device.
The Zero Gecko device is also the only Cortex-M0 + MCU containing 128-bit high-grade encryption standards (AES) hardware modules. With built-in hardware AES encryption engine, the Zero Gecko MCU can become an ideal matching device for RF transmitters and transceivers on the Internet of Things.
GEIR FøRRE, General Manager, Senior Vice President, Silicon Labs, said, "The Internet of Things is a huge and exciting market, which can completely consume low cost, battery power supply connection equipment and wireless sensor node. To build. The Internet of Things market requires low power-based Cortex-M0 + MCUs, and can save energy and system costs. Our new EFM32 Zero Gecko MCU has very competitive prices, making developers to create excellent Embedded embedded systems with other Cortex-M0 / 0 + MCUs. "
EFM32 Zero Gecko Series products are close to 250 EFM32 Gecko MCU product pins and software compatible with Silicon Labs. This compatibility provides developers with a cost-effective low-energy design starting point, which can be easily upgraded to high-performance Gecko devices, including a new type of Wonder Gecko product based on ARM Cortex-M4 kernel, which has a complete DSP instruction set and dedicated Floating point processing unit.
Free software tools shorten products
In order to shorten the product listing time and reduce development costs, EFM32 Zero Gecko series products support free Simplicity Studio software development kits, this complete graphical user interface development environment supports all mainstream computing platforms, including Microsoft® Windows®, Linux and Mac / OS X. With Zero Gecko entry-level kit, free Simplicity Studio provides developers to access all information, documentation, EnergyAware tools, software, and source code libraries, can quickly develop low-energy applications.
The core features of Simplicity Studio include EnergyAware Profiler, which is a powerful and easy-to-use Debug tool for developing low-power embedded systems; and EnergyAware Designer, this is a tool for simplifying debug I / O pins conflicts, The class task is time consuming. Using these EnergyAware tools, developers can set the I / O pin quickly and generate code. Simplicity Studio also includes an EnergyAware software library built around the ARM standard CMSIS abstraction and is supported by the leading toolchain. These third-party tools include the IAR's Embedded Workbench, Keil's MDK-ARM and ROWLEY Associates' Crossworks.
Price and availability
Silicon Labs EFM32 Zero Gecko MCU has access to samples, support QFN and QFP packaging, with 4-32kb Flash size, planned in the fourth quarter of 2013. When the Zero Gecko MCU is at 100,000 pieces, the unit price is from 0.49. In addition, easy to use and low-cost EFM32ZG-STK3200 entry-level kits are now available, the price is $ 69.
