Automotive SimpleLink™ Bluetooth® LE wireless MCU with 1MB flash, HSM, APU, CAN-FD | RHA | 40 | -40 to 125

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 features in Bluetooth 6.0 and earlier versions:

* LE Coded PHYs (Long Range), LE 2Mbit PHY (high

speed), advertising extensions, multiple

advertisement sets, CSA#2, as well as backward

compatibility with earlier Bluetooth Low Energy specifications

*

Bluetooth Channel Sounding technology support and an Algorithm Processing Unit (APU) to enable high accuracy, low cost, and a secure phase-based ranging mechanism for distance estimation

*

APU enables latency and power-efficient execution of distance-ranging signal processing algorithms, including FFT, super-resolution complex algorithms like MUltiple SIgnal Classification (MUSIC), and neural network algorithms.

*

ArmCustom 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:

* An 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 an 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 in the P version; thereby, enabling a reduced 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 a rich toolset. 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.
