Multiband SoCs support full Bluetooth 5 connectivity and different memory options

June 14, 2017 // By Julien Happich
Silicon Labs has expanded its Wireless Gecko system-on-chip (SoC) portfolio with new multiband SoCs supporting full Bluetooth 5 connectivity and more memory options.

The EFR32xG13 family supports all Bluetooth 5 features and capabilities, enabling four times the range, twice the speed and eight times greater broadcasting capacity than Bluetooth 4, as well as improved co-existence with other wireless protocols. The SoCs feature a 2 Mbps PHY that supports faster throughput or reduced power consumption due to lower transmit (TX) and receive (RX) times. The SoCs also integrate a new 125 kbps and 500 kbps coded PHY that enables much longer communications, quadrupling the range of Bluetooth connections compared to existing devices running Bluetooth 4. 

The chips provide sufficient flash memory (512 kB) and RAM (64 kB) to run applications using zigbee, Thread and Bluetooth 5 in single-protocol mode and to support multiprotocol combinations of Bluetooth with zigbee, Thread or proprietary stacks (running on sub-GHz or 2.4 GHz networks). The new SoCs also include an on-chip oscillator that eliminates the need for an external 32 KHz crystal typically required for Bluetooth low energy devices. Sleep current is now six percent lower than EFR32xG12 SoCs and 44 percent lower than first-generation Wireless Gecko devices.

EFR32xG13 Wireless Gecko SoC samples and production quantities are available now in 7x7 mm QFN48 packages.
