2.2.1.2.1 CC1352R

The CC1352R device is a multiprotocol and multi-band Sub-1 GHz and 2.4 GHz wireless microcontroller (MCU) targeting Thread, Zigbee®, Bluetooth® 5 Low Energy, IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), proprietary systems, including the SimpleLink™ TI 15.4-Stack (Sub-1 GHz and 2.4 GHz), and concurrent multiprotocol through a Dynamic Multiprotocol Manager (DMM) driver. The device is optimized for low-power wireless communication and advanced sensing in building security systems. The highlighted features of this device include:

  • Wide flexibility of protocol stack support in the SimpleLink CC13R2R Software Development Kit (SDK).
  • Maximum transmit power of +14 dBm at Sub-1 GHz with 24.9 mA and +5 dBm at 2.4 GHz with 9.6 mA current consumption.
  • Longer battery life wireless applications with low standby current of 0.85 A and full RAM retention.
  • Industrial temperature ready with lowest standby current of 11 μA at 105 ⁰C.
  • Advanced sensing with a programmable, 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.
  • Low SER (Soft Error Rate) FIT (Failure-in-time) for long operation lifetime with no disruption for industrial markets with always-on SRAM parity against corruption due to potential radiation events.
  • Dedicated software-controlled radio controller (Arm® Cortex®-M0) providing flexible low-power RF transceiver capability to support multiple physical layers and RF standards.
  • Excellent radio sensitivity (–121 dBm) and robustness (selectivity and blocking) performance for SimpleLink long-range mode.
