Energy Micro launches dev kit for Giant EFM32


Energy Micro has announced the availability of a development kit supporting their ARM Cortex-M3-based EFM32 Giant Gecko microcontrollers. The EFM32GG-DK3750 provides users with full J-Trace and J-Link support plus access to the Giant Gecko´s low energy features, including a backup power domain, optional USB connectivity, TFT display drivers, and a 400nA energy mode.

The kit features a 10×10 BGA112 packaged Giant Gecko microcontroller, and includes a 320×240 resistive touch color TFT display, 16MB NOR-Flash and 4MB PSRAM, MicroSD card support, audio I/O, I2S DAC, a USB port, connectors for an integrated Low Energy UART, and a 10/100 Mbit/s SPI based MAC/PHY. A host of user switches, LEDs, 5-axis joystick, and debug and trace plugs are provided, with SEGGER J-Trace and J-Link available via the USB interface, which also powers the kit.

40 different EFM32 Giant Gecko configurations are available in 9 different package options, including a new small form factor 7x7mm BGA120. The EFM32 MCU family supports speeds up to 48MHz and offers up to 1024KB Flash and 128KB RAM memory. Pin- and code-compatible with the EFM32 Gecko and Tiny Gecko microcontrollers families, the company claims the Giant Gecko has an energy usage a quarter of that of alternative 8-, 16-, or 32-bit microcontrollers.

The development kit’s display is driven by Giant Gecko´s built-in TFT driver, which handles updates without CPU intervention. Its USB driver supports fourteen 2KB buffered end points and OTG protocol. A separate backup power domain prevents data loss in battery-operated applications. Additional low energy peripherals include LESENSE for autonomous control of up to 16 sensors, three on-chip op amps, and a 400nA sleep mode with RTC and USB wake-up support.

Equipped with Gecko technology, EFM32 microcontrollers are capable of an active current consumption of 160uA/MHz, Deep Sleep Modes with RTC running at 400nA, and a 20nA shut off mode with GPIO wake-up, with a wake-up time from sleep modes of 2us.

The supporting Simplicity Studio software tools suite is free to download at Energy Micro's Simplicity Studio page.

The EFM32 Giant Gecko microcontrollers are available now and are priced from $3.53 USD each in quantities of 100k, for 512KB Flash and 128KB RAM configurations. The EFM32 Giant Gecko Development Kit price is $349USD. More information available at Energy Micro's Giant Gecko Development Kit page
