EFR32FG14P231F256IM48-B

EFR32FG14P231F256IM48-B EFR32FG14 series 1 wireless Flex Gecko proprietary protocol SoC is targeted at proprietary wireless applications for secure, connected wireless devices. The device includes an ARM Cortex-M4 based microcontroller (MCU) and provides a maximum output power of 20dBm. With a receive sensitivity of -126.2 (600bps GFSK 915 MHz) dBm (2.4kbps, 2 GFSK 0.1% BER) this supports a full DSP instruction set and floating-point unit to speed computation. Built with low-power Gecko technology which includes innovative low energy techniques, fast wake-up times and energy saving modes, this is ideal for energy sensitive applications. In addition, this device includes 256KB flash, 32KB RAM, 32 GPIO pins, 8 x 16bit timers and multiple communication interfaces. Typical applications are home and building automation and security, metering, electronic shelf labels, industrial automation, commercial and retail lighting and sensing.
