Sub-1G - BDE-SG1312R7(Sub-1G Based on CC1312R7)
  • BDE-SG1312R7(Sub-1G Based on CC1312R7)


    The BDE-SG1312R7 is a multiprotocol Sub-1 GHz wireless microcontroller (MCU) supporting IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), mioty®, Wi-SUN®, proprietary systems, including the TI 15.4-Stack (Sub-1 GHz), and concurrent multiprotocol through a Dynamic Multiprotocol Manager (DMM) driver. The BDE-SG1312R7 is based on an Arm® Cortex® M4F 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-SG1312R7 has a software defined radio powered by an Arm® Cortex® M0, which allows support for multiple physical layers and RF standards. The device supports operation in 915-MHz frequency bands. PHY and frequency band switching can be done runtime through a dynamic multiprotocol manager (DMM) driver. The BDE-SG1312R7 has an efficient built-in PA that supports +14 dBm TX at 24.9 mA current consumption. In RX it has -122 dBm sensitivity and 88 dB blocking ±10 MHz in SimpleLink™ long-range mode with 2.5-kbps data rate. 

    The BDE-SG1312R7 has a low sleep current of 0.9 μA with RTC and 144KB RAM retention. In addition to the main Cortex® M4F processor, the device also has an autonomous ultra-low power Sensor Controller CPU with fast wake-up capability. As an example, the sensor controller is capable of 1-Hz ADC sampling at 1-μA system current. The BDE-SG1312R7 has Low SER (Soft Error Rate) FIT (Failure-in-time) for long operational lifetime. Always-on SRAM parity minimizes risk for corruption due to potential radiation events. Consistent with many customers’ 10 to 15 years or longer life cycle requirements.

    The module is with dimension of 22 mm x 15 mm x 2.15 mm, it has a U.FL connector for connecting an external antenna or it can be configured to use the RF pad for connecting the antenna in application board.
