STEVAL-KIRXB2CB

The STEVAL-KIRXB2CB is a Ki cordless kitchen receiver, specifically designed for blender appliances to be powered and controlled via a Ki wireless power transmitter (STEVAL-KITXCB).

Ki cordless kitchen is a relatively new standard for wireless power initiated by the Wireless Power Consortium (WPC). This standard targets to replace traditional kitchen appliances using power cords (for example, mixer, toaster, rice cooker, coffeemakers) and to combine eventually with induction cooktop with efficiency > 90% of equivalent corded devices required up to 2.2 kW.

Thanks to the ST25R3918 multipurpose NFC transceiver, the system ensures seamless communication and power negotiation with the base station (PTx) to optimize power transfer in static mode and ensure safety compliance.

The STEVAL-KIRXB2CB also integrates energy harvesting to power up the user interface, minimize standby energy consumption, and support low-power functions independently of the main power transfer.

Secure device authentication and pairing with the PTx is achieved using the STSAFE secure element, providing reliable verification.

The compact form factor evaluation board is designed to address space constraints typical in modern kitchen appliances, enabling appliance manufacturers to innovate with form factors and aesthetics, supporting sleek, modern kitchen designs aligned with consumer preferences.
