NXH3670UK Datasheet | NXP Semiconductors

description The NXH3670UK constitutes a highly integrated, single chip ultra-low power 2.4 GHz wireless transceiver with embedded MCU, targeted at wireless audio streaming for hearables, wireless headsets, and headphones. The NXH3670UK chip integrates the following key functionalities - among others: - A 2.4 GHz RF transceiver and digital modem supporting up to 2 Mbits/s - Supporting Bluetooth Low Energy GFSK modulation 1 Mbps and 2 Mbps - A low-power 16 MHz/32 MHz crystal oscillator and on-chip oscillators - An RF MAC for supporting the lower protocol layers - A Cortex-M0 subsystem for system control and higher protocol layers - An AES-128 security coprocessor - Audio interfaces and audio processing accelerators - A Cool Flux DSP for audio processing - Multiple user interfaces for control, data, debug, and test CAUTION This device is sensitive to Electro Static Discharge (ESD). Observe precautions for handling electrostatic sensitive devices. Such precautions are described in the ANSI/ESD S20.20, IEC/ST 61340-5, JESD625-A, or equivalent standards. CAUTION Semiconductors are light sensitive. Exposure to light sources can cause the IC to malfunction. The IC must be protected against light. The protection must be applied to all sides of the IC. Unless otherwise specified: - Typical values are at room temperature (25 °C) with nominal supply voltages of 1.2 V. - Minimum/Maximum values are valid over operating temperature and voltage range as specified in Table 26.
