Single Wire Interface

The RYZ012 supports the Single Wire interface (SWIRE). SWM (Single Wire Master) and SWS (Single Wire

Slave) represent the master and slave device of the single wire communication system. The maximum data

rate can be up to 2 Mbps.

The Single Wire Interface is used for device programming.

Bluetooth LE RF Transceiver

The RYZ012 integrates an advanced Bluetooth LE RF transceiver. The RF transceiver works in the

worldwide 2.4-GHz ISM (Industrial Scientific Medical) band.

The transceiver consists of a fully integrated RF synthesizer, a Power Amplifier (PA), a Low Noise Amplifier

(LNA), a TX filter, an RX filter, a TX DAC, an ADC, a modulator, and a demodulator. The transceiver can be

configured to work in standard-compliant 1-Mbps Bluetooth LE mode, 2-Mbps enhancement Bluetooth LE

mode, 125-kbps Bluetooth LE long-range mode (S8), and 500-kbps Bluetooth LE long-range mode (S2). The

internal PA can deliver a maximum 10dBm output power, avoiding the need for an external RF PA.

Figure 4 shows a block diagram of the RF transceiver.
