3 Description

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

(MCUs) supporting Bluetooth® Low Energy 5.4 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® 5.4 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 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 MUltiple SIgnal Classification (MUSIC)

• 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:

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

number generation operations

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
