Antenna for tricky situations: WBZ451UE 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 with WBZ451UE module, you do not need to be an RF-expert to add wireless to your end application. WBZ451UE module is RF-ready, saving you precious time and RF-design costs.

Global regulatory-certified: RF certification can take a lot of time and money. WBZ451UE modules are pre-certified in US, Canada, Europe, China, Taiwan, Japan, and Korea so you can focus on your end product and go to market quicker.

Hardware arbiter for reliable multi-protocol operation: Build applications with Bluetooth and Zigbee working simultaneously, reliably.

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.
