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 fogs 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 (2 Mbps PHY), Long Range (LE Coded 125 kbps and

500 kbps PHYs), Privacy 1.2.1 and Channel Selection Algorithm #2, as well as backwards compatibility and

support for key features from the Bluetooth ® 4.2 and earlier Low Energy specifications.

• Fully-qualified Bluetooth ® 5.3 software protocol stack included with the SimpleLink™ CC23xx Software

Development Kit (SDK).

• Ultra-low standby current less than 0.71 μA 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

(-102 dBm for 125 kbps 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, Sub-1 GHz 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
