The EFM32 Zero Gecko MCUs feature many of the same power-saving precision analog peripherals included in Silicon Labs’ popular Tiny Gecko, Giant Gecko and Wonder Gecko devices. These low-energy peripherals include an analog comparator, a supply voltage comparator, an on-chip temperature sensor and a 12-bit analog-to-digital converter (ADC) with 350 μA current consumption at a 1 MHz sample rate.The EFM32 Zero Gecko devices are the only Cortex-M0+ MCUs on the market that integrate a programmable current digital-to-analog converter (IDAC). This on-chip precision-analog IDAC generates a biasing current from 0.05-64 µA with only 10 nA overhead. The IDAC provides an accurate bias and/or control capability for companion ICs and other external circuits including amplifiers, sensors, Wheatstone bridges and resistor ladders, thereby eliminating the need for external power amplifier components for many cost-sensitive applications. The Zero Gecko devices are also the only Cortex-M0+ MCUs containing a 128-bit Advanced Encryption Standard (AES) hardware block. With this built-in hardware AES encryption acceleration support, the Zero Gecko MCUs provide an ideal companion for RF transmitters and transceivers used in connected device applications for the Internet of Things. “The Internet of Things is a huge and exciting market made possible by low-cost, battery-powered connected devices and wireless sensor nodes that sip nanoamps of energy,” said Geir Førre, senior vice president and general manager of Silicon Labs’ microcontroller products. “The IoT market requires battery-friendly Cortex-M0+ based MCUs that save both energy and system cost. Our new EFM32 Zero Gecko MCUs – shipping now at very cost-competitive prices – enable developers to create embedded systems that are four times more energy-efficient than possible with other Cortex-M0/0+ MCUs.” The EFM32 Zero Gecko family is pin- and software-compatible with Silicon Labs’ broad portfolio of nearly 250 EFM32 Gecko MCU products. This compatibility provides developers with a cost-effective, energy-friendly entry point to higher-performance Gecko devices including the new Wonder Gecko based on the ARM Cortex-M4 core featuring a full DSP instruction set and dedicated floating point unit (FPU).
Complimentary Software Tools for Faster Time to MarketTo speed time to market and reduce development cost, the EFM32 Zero Gecko family is supported by the complimentary Simplicity Studio software suite, a comprehensive graphical user interface environment for all major computing platforms including Microsoft® Windows®, Linux and Mac/OS X. Available with the Zero Gecko starter kit at no charge, Simplicity Studio provides developers with one-click access to all the information, documentation, energyAware tools, and software and source code libraries needed to quickly develop energy-friendly applications. Key elements of Simplicity Studio include the energyAware Profiler, a powerful yet easy-to-use debugging tool for low-energy embedded system development, and the energyAware Designer, a tool that eases the traditionally time-consuming task of debugging I/O pin conflicts. Using these energyAware tools, developers can quickly drill down to the exact lines of code that are consuming the most power. Simplicity Studio also includes an energyAware software library built around ARM’s standard CMSIS abstraction layer and supported by leading tool chains. Third-party tools support includes IAR’s Embedded Workbench, Keil’s MDK-ARM and CrossWorks from Rowley Associates. Pricing and Availability Samples of Silicon Labs’ EFM32 Zero Gecko MCUs are available now in QFN and QFP packages with 4 to 32 kB flash sizes, and production quantities are planned for Q4 2013. Product pricing for the Zero Gecko MCUs in 100,000-unit quantities begins at $0.49 (USD). The easy-to-use, cost-effective EFM32ZG-STK3200 starter kit is available now and priced at $69 (USD MSRP).
