描述 Description

The SimpleLink? CC2642R-Q1 device is an AEC-Q100 compliant wireless microcontroller (MCU) targetingBluetooth 5 Low Energy automotive applications. The device is optimized for low-power wireless communication in applications such as car access including passive entry passive start (PEPS) and remote keyless entry (RKE), battery management systems (BMS), car sharing, piloted parking, cable replacement, and smartphone connectivity. The highlighted features of this device include:Support for Bluetooth ??5.1 features: LE Coded PHYs (Long Range), LE 2-Mbit PHY (High Speed), Advertising Extensions, Multiple Advertisement Sets, CSA#2, as well as backwards compatibility and support for key features from the Bluetooth ??5 and earlier Low Energy specifications. Fully-qualified Bluetooth ??5.1 software protocol stack included with the SimpleLink? CC13x2 and CC26x2 Software Development Kit (SDK), which enables Angle of Arrival (AoA). Longer battery life wireless applications with low standby current of 0.94?μA with full RAM retention. AEC-Q100 qualified at the Grade 2 temperature range (–40?°C to +105?°C) and is offered in a 7-mm x 7-mm VQFN package with wettable flanks. Dedicated software controlled radio controller (Arm? Cortex?-M0) providing flexible low-power RF transceiver capability to support multiple physical layers and RF standards, such as real-time localization (RTLS) technologies. Excellent radio sensitivity and robustness (selectivity and blocking) performance for Bluetooth ? Low Energy (-105?dBm for 125-kbps LE Coded PHY).

The CC2642R-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.
