Sub-1G - BDE-SG1311R3(Sub-1G Based on CC1311R3)
  • BDE-SG1311R3(Sub-1G Based on CC1311R3)


    The BDE-SG1311R3 is a multiprotocol Sub-1 GHz wireless module series that provides two options: BDE-SG1311R3U (U.FL connector version) and BDE-SG1311R3N (RF pad out version). The module supports IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), mioty, proprietary systems, and TI 15.4-Stack (Sub-1 GHz). The module is based on an Arm® Cortex® M4 main processor and optimized for low-power wireless communication and advanced sensing in grid infrastructure, building automation, retail automation, personal electronics and medical applications.

    The BDE-SG1311R3 has a software defined radio powered by an Arm® Cortex® M0, which allows support for multiple physical layers and RF standards. The device supports 861 to 1054-MHz frequency band. The module has an efficient built-in PA that supports +14 dBm TX at 24.9 mA current consumption. In RX it has -121 dBm sensitivity and 88 dB blocking ±10 MHz in SimpleLink™ long-range mode with 2.5-kbps data rate.

    The module has a low sleep current of 0.7 μA with RTC and 32KB RAM retention. Consistent with many customers’ 10 to 15 years or longer life cycle requirements. BDE-SG1311R3 integrates all required system-level hardware components including clocks, passives and low-cost PCB design.
