Silicon Labs has expanded its energy-friendly EFM32 Gecko portfolio with industrial-strength microcontrollers (MCUs) delivering higher performance, more features and lower power. The new EFM32GG11 Giant Gecko family targets smart metering, asset tracking, industrial/building automation, wearables and personal medical applications.
The MCUs combine peak 72 MHz processing performance, large memory options, peripherals and hardware accelerators, and comprehensive software tools including the Micrium OS. They are based on an ARM Cortex-M4 processor core and come with up to 2 MB Flash and 512 KB RAM, in addition to SD/MMC and Octal/Quad-SPI memory interfaces.
Communication interfaces and controllers include a 10/100 Ethernet MAC; secure digital input output (SDIO) Wi-Fi interface; single or dual CAN bus controllers; crystal-free USB controller; TFT display hardware acceleration with per-pixel alpha blending and ultra-low-energy segment LCD driver; and current-based capacitive sense engine.
Giant Gecko MCUs are available in a wide range of QFN, QFP and BGA package options with up to 192 pins, including many packages that are footprint-compatible with existing EFM32 MCUs. Software compatibility across the entire EFM32 MCU and EFR32 Wireless Gecko SoC portfolio enables broad software reuse and reduced design time and cost for developers.
