Antenna for tricky situations: WBZ351UE comes with a U.FL connector for external antenna so you can add wireless to applications where a PCB antenna doesn't work.  

RF-ready: RF design is complicated but the WBZ351 makes it easier. With our RF-ready, U.FL antenna, you don’t need to be an RF-expert to add wireless to your application, saving you time and RF-design costs.

Global regulatory-certified: Radio certification is also complicated and can take a long time to complete. Our WBZ351UE modules are pre-certified in US, Canada, Europe, China, Taiwan, Japan and Korea helping you go to market quicker.

Ultra-low power 2.4 GHz transceiver: Build applications enabling Bluetooth Low-Energy (LE) 6.0 IEEE^® 802.15.4 / Zigbee 3.0 connectivity with hardware-level arbitration for multi-protocol wireless functionality.

Hardware-based security (secure boot): Protect applications with NIST-compliant authentication and secure boot ROM to ensure only trusted software runs on your system

Robust Analog Peripherals: Industrial-grade capacitive touch, ADCs, DAC and comparators enable versatile sensor integration and analog management for a wide range of applications.

Functional safety: This device supports the ISO 26262 (ASIL B), and IEC 61508 (SIL 2) functional safety standards. The Functional Safety Manual, FMEDA and Diagnostic Software information are available under NDA. Contact us for more information.
