3 Description

The SimpleLink™ CC274xR-Q1 and CC274xP-Q1 devices are AEC-Q100 complaint wireless microcontrollers

(MCUs) supporting Bluetooth® Low Energy 6.0 for automotive applications. These devices are optimized for

low-power wireless communication in applications such as car access including passive entry passive start

(PEPS), phone as a key (PaaK), and remote keyless entry (RKE). The key features of this device include:

• Support for Bluetooth® 6.0 and earlier version features:

– LE Coded PHYs (Long Range), LE 2Mbit PHY (high speed), advertising extensions, multiple

advertisement Sets, CSA#2, as well as backward compatibility with earlier Low Energy specifications.

– Bluetooth® Channel Sounding technology and Algorithm Processing Unit (APU) to enable high accuracy,

low cost, and secure phase-based ranging mechanism for distance estimation.

• APU enables latency and power-efficient execution of distance-ranging signal processing algorithms

including FFT and super-resolution complex algorithms like MUSIC (MUltiple SIgnal Classification) at

the lowest energy consumption.

• Arm (Custom Data Extension) CDE instruction support for machine learning acceleration

• Fully qualified Bluetooth software protocol stack included with the SimpleLink™ Low Power F3 Software

Development Kit (SDK)

• Advanced security features for connected wireless MCUs:

– Isolated HSM environment with a dedicated controller handling accelerated cryptographic and random

number generation operations

– Secure boot and firmware updates with the root of trust enabled by immutable system ROM

– ARM Cortex M33 TrustZone-M based trusted execution environment support

– Secure key storage support with HSM and TrustZone-M

– Hardware fault sensors to mitigate low-cost, low-effort, non-invasive physical attack threats like voltage

glitch injection.

– Dedicated AES-128 HW accelerator for handling timing critical link layer encryption/decryption operations

• Ultra-low standby current with full 162KB SRAM retention and RTC operation that enables significant battery

life extension, especially for applications with longer sleep intervals.

• Extended temperature support with the lowest standby current

• Integrated BALUN and integrated RF switch to support both transmit and receive operations on the same RF

pin even for the P version; thereby, enabling reduced a bill-of-material (BOM) board layout

• Excellent radio sensitivity and robustness (selectivity and blocking) performance for Bluetooth Low Energy

The CC274xR/P-Q1 devices are 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
