Automotive SimpleLink™ Bluetooth® LE wireless MCU with 864kB flash, HSM, APU

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.
