nRF24Z1 is a single chip 2.4GHz RF transceiver supporting MP3/Mini Disk headset, CD quality headset, surround speakers, microphone, musical instruments etc audio applications.
The nRF24Z1 wireless audio streamer is a 4 Mbit/s single‑chip RF transceiver that operates in the worldwide 2.4 GHz license‑free ISM band. It provides CD‑quality audio streaming up to 16‑bit 48 kSPS, with standard digital audio interfaces (I2S, S/PDIF) and optional on‑chip compression. Control and configuration are handled via SPI or 2‑wire (I²C‑compatible) serial interfaces, and the device includes embedded voltage regulators for operation from a single 2.0 V to 3.6 V supply.
The specification details pin assignments, electrical characteristics, and power‑saving modes, making the nRF24Z1 suitable for compact audio applications such as CD players, headsets, speakers, and musical instruments. It can be used with or without an external microcontroller, and supports a quality‑of‑service engine for reliable RF link management.
