NFMI Radio for Wireless Audio and Data Streaming

Not recommended for new designs, please refer to

NXH2261UK when starting a new design

The NXH2281UK is an ultra-low-power wireless single-chip solution optimized for audio and data communication. It uses a magnetic induction radio to provide a robust, tightly

contained body area network around each user. It uses Near Field Magnetic Induction (NFMI) for wireless audio and data streaming.

It offers a fully integrated Arm® Cortex®-M0-based control subsystem, a Magnetic Induction (MI) transceiver, an audio data path and a power

management subsystem.

In addition to the Arm Cortex-M0, the control subsystem embeds a 512 kbit EEPROM and a set of standard interfaces.

The audio data path is based on hardware-accelerated audio processing blocks and can be enhanced with a user-programmable CoolFlux DSP®. The integrated power

management subsystem supports multiple power domains and runs directly from a ZnAir or NiMH battery.

The device is available in a Wafer-Level Chip-Scale (WLCSP) package.
