Silicon Labs has expanded its EFM32 Gecko MCU portfolio with the addition of devices offering higher performance, more features and lower power consumption.
The EFM32GG11 Giant Gecko MCU family is said to offer the most advanced feature set available in the low-power MCU market, targeting smart metering, asset tracking, industrial/building automation, wearables and personal medical applications. The ARM Cortex-M4 based MCUs run at up to 72MHz and offer a range ofmemory options, peripherals and hardware accelerators.
Parts are available with up to 2Mbyte or flash and 512kbyte of RAM, as well as with SD/MMC and Octal/Quad-SPI memory interfaces. Consuming 77μA/MHz in active mode and 1.6μA in deep sleep mode, the MCUs are supplied with a 10/100 Ethernet MAC and an SDIO Wi-Fi interface. Single or dual CAN bus controllers can be specified and there is also a crystal-free USB controller.
Giant Gecko MCUs are available in a range of QFN, QFP and BGA packages with up to 192 pins. Many of the new additions are said to be footprint-compatible with existing EFM32 MCUs.
