Silicon Labs' EFM32 Giant Gecko kit 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 and TFT display drivers, and a 400 nA energy mode.
The development kit features a 10 x 10 BGA112 packaged Giant Gecko microcontroller, and includes a 320 x 240 resistive touch color TFT display, 16 MB NOR-Flash and 4 MB 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.
Forty different EFM32 Giant Gecko configurations are now available in nine different package options, including a small form factor 7 mm x 7 mm BGA120. The MCU family supports speeds up to 48 MHz and offers up to 1024 KB Flash and 128 KB 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 2 KB 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 400 nA sleep mode with RTC and USB wake-up support.
