- BDE-SG1311R3(Sub-1G Based on CC1311R3)
-
- General Description
The BDE-SG1311R3 is a multiprotocol Sub-1GHz wireless module series based on Texas Instrument (TI)’s single-chip wireless microcontroller (MCU) CC1311R31T0RGZR. In order to fulfil different integration scenarios, BDE provides different variants for this module series. They are listed and described in Table 1.
The BDE-SG1311R3 module series is embeded with an powerful 48-MHz Arm® Cortex®-M4 processor which supports IEEE 802.15.4, IPv6-enabled smart objects (6LoWPAN), mioty, proprietary systems, including TI 15.4-Stack (Sub-1GHz). The module series is 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 low sleep current of 0.7 μA with RTC and 32KB RAM retention, which enables longer battery life wireless applications. The module supports +14 dBm output power with best-in-class transmit current consumption at 24.9 mA for Sub-1GHz operation. This is suitable for the long-range and low-power applications. The device also has an autonomous ultra-low power Sensor Controller CPU with fast wake-up capability.
The module series has a software defined radio powered by an Arm® Cortex® M0 which allows support for multiple physical layers and RF standards.
The module series integrates all required system-level hardware components including clocks, balun filter, other passives, and PCB trace antenna or U.FL connector into a small PCB form factor. It is for easy assembly and low-cost PCB design.
The module is pre-certified with FCC, ISED, CE to make easy integration and fast time-to-market for customers.
