Gecko MCUs offer more features, lower power

---

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.
