3 Description
The SimpleLink™ CC2340R5-Q1 device is an AEC-Q100 compliant wireless microcontroller (MCU) targeting
Bluetooth 5 Low Energy automotive applications. The device is optimized for low-power wireless communication
in applications such as tire pressure monitoring systems (TPMS), car access, including key fobs used in passive
entry passive start (PEPS) and remote keyless entry (RKE), cable replacement, and smartphone connectivity.
The highlighted features of this device include:
• Support for Bluetooth 5 features: high-speed mode (2Mbps PHY), long-range (LE Coded 125kbps and
500kbps PHYs), privacy 1.2.1 and channel selection algorithm #2, as well as backward compatibility and
support for key features from the Bluetooth 4.2 and earlier Low Energy specifications.
• Fully qualified Bluetooth 5.4 software protocol stack included with the SimpleLink™ CC23xx Software
Development Kit (SDK)
• Ultra-low standby current less than 0.71μA with RTC operational and full RAM retention that enables
significant battery life extension, especially for applications with longer sleep intervals.
• Integrated balun for reduced bill-of-material (BOM) board layout
• Excellent radio sensitivity and robustness (selectivity and blocking) performance for Bluetooth Low Energy
(–102dBm for 125kbps LE Coded PHY, with integrated balun)
The CC2340R5-Q1 device is part of the SimpleLink™ MCU platform, which consists of Wi-Fi, Bluetooth Low
Energy, Thread, Zigbee, Sub1GHz MCUs, and host MCUs that all share a common, easy-to-use development
environment with a single core software development kit (SDK) and rich tool set. A one-time integration of the
SimpleLink™ platform enables you to add any combination of the portfolio’s devices into your design, allowing
100 percent code reuse when your design requirements change. For more information, visit SimpleLink™ MCU
