The development 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. There are now 40 different EFM32 Giant Gecko configurations available in nine different package options, including a new small form factor 7x7mm BGA120.
The 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, Giant Gecko can demonstrate 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 only 160uA/MHz, Deep Sleep Modes with RTC running at only 400nA and a 20nA shut off mode with GPIO wake-up, with a wake-up time from sleep modes of only 2us.
