The devices also support a robust set of peripherals, including a hardware crypto accelerator, 12-bit analog-to-digital converter (ADC), digital-to-analog-converter (DAC), a 12-channel Peripheral Reflex System, and various communication interfaces. The Bluetooth 5 standard enables four times the range, twice the speed, and 800 percent greater broadcasting capacity plus improved co-existence with other wireless IoT protocols. The SoCs feature a 2 Mbps Bluetooth PHY, providing ample throughput for applications running a Bluetooth 5-compliant stack. This significant memory expansion makes it easier to develop complex, feature-rich Internet of Things (IoT) applications supporting multiple protocol stacks, real-time operating systems such as Micrium OS, backup images for devices and over-the-air (OTA) updates for field upgrades to extend the life of IoT products. The devices offer more memory than previous generations of Blue Gecko devices, with EFR32BG12 devices offering 1 Mbyte of flash memory and 256 kbytes of RAM, while the EFR32BG13 devices offer 512 kbytes of flash memory and 64 kbytes of RAM. Silicon Labs’ EFR32BG12 and EFR32BG13 Blue Gecko SoCs, available from Mouser Electronics, integrate a high-performance 32-bit 40 MHz ARM Cortex-M4 core with a 2.4 GHz and sub-1GHz radio transceiver. Part of the Wireless Gecko portfolio, these Bluetooth low energy SoCs deliver superior RF performance, enhanced cryptography acceleration, larger memory options, on-chip capacitive touch control, and additional low-power peripherals and sensor interfaces. is now stocking the EFR32BG12 and EFR32BG13 Blue Gecko systems-on-chips (SoCs) from Silicon Labs.
