New Automotive BLE 5.4 Chip for Wireless Battery Management Systems

Infineon Technologies has recently introduced eight new BLE Bluetooth devices to its Airoc range, catering to various applications including automotive systems. Among these additions is the Airoc CYW20829 BLE Bluetooth Low Energy 5.4 microcontroller (MCU) family, which comprises System-on-Chip (SoC) devices and wireless modules specifically optimized for wireless battery management systems (BMS) and vehicle access designs.

The AIROC CYW89829 Bluetooth Low-Energy MCU is a standout product in this range, targeting car access and wireless BMS applications. It boasts robust RF performance, long-range capabilities, and incorporates the latest Bluetooth 5.4 features such as PAwR (Periodic Advertising with Responses).

Featuring a dual ARM Cortex M33 core with separate 96MHz application and 48MHz Bluetooth Low Energy subsystem cores, the CYW89829 offers a 10 dBm output power without a PA, integrated flash, CAN FD, crypto accelerators, high security including Root of Trust (RoT), and is PSA level 1 ready. It is automotive AECQ-100 Grade 2 qualified with a 105°C operating temperature limit.

The high integration of the CYW20829 product family enables designers to reduce bill-of-material (BOM) costs and device footprint across a wide range of applications, including PC accessories, wearables, health and lifestyle products, home automation, and more.

Shantanu Bhalerao, Vice President of the Bluetooth Product Line at Infineon Technologies, emphasized the company's commitment to providing robust connectivity and cutting-edge features through their Bluetooth solutions. He highlighted the advantages of the automotive CYW89829 BLE MCU and versatile CYW20829 MCU in delivering ultra-low power and high integration for enhanced user experiences in automotive, industrial, and consumer markets.
