The XN297L series datasheet describes a 2.4 GHz single‑chip wireless transceiver with low power consumption, configurable data rates, and detailed pin…
The XN297L series chip operates in the 2.400‑2.483 GHz ISM band and integrates a RF transceiver, frequency synthesizer, crystal oscillator, and modem. It supports one‑to‑many networking, ACK‑based communication, and offers configurable output power, channel, and data rate.
Key specifications include a supply voltage of 2.2‑3.3 V, sleep current of 2 µA, TX output up to 13 dBm, and RX sensitivity down to –91 dBm at 250 kbps. The device is available in QFN20L0303, SOP16 and SOP8 packages and requires only five external components (one crystal and four capacitors). This manual is written in Chinese.
