Functional Description HopeRF's RFM23BP are highly integrated,low cost,433/868/915MHz wireless ISM transceivers module . The wide operating voltage range of 3.3–6V and low current consumption makes theRFM23BP an ideal solution for battery powered applications. The RFM23BP operates as a time division duplexing (TDD) transceiver where the device alternately transmits and receives data packets. The device uses a single-conversion mixer to downconvert the 2-level FSK/GFSK/OOK modulated receive signal to a low IF frequency. Following a programmable gain amplifier (PGA) the signal is converted to the digital domain by a high performance ΔΣ ADC allowing filtering, demodulation, slicing, and packet handling to be performed in the built-in DSP increasing the receiver’s performance and flexibility versus analog based architectures. The demodulated signal is then output to the system MCU through a programmable GPIO or via the standard SPI bus by reading the 64-byte RX FIFO. A single high precision local oscillator (LO) is used for both transmit and receive modes since the transmitter and receiver do not operate at the same time. The LO is generated by an integrated VCO and ΔΣ Fractional-N PLL synthesizer. The synthesizer is designed to support configurable data rates, output frequency and frequency deviation at 433MHz,868MHz,915MHz band. The transmit FSK data is modulated directly into the ΔΣ data stream and can be shaped by a Gaussian low-pass filter to reduce unwanted spectral content. The RFM23BP PA output power can be configured between +10 and +30 dBm ,. The RFM23BP supports frequency hopping, TX/RX switch control, and antenna diversity switch control to extend the link range and improve performance The RFM23BP is designed to work with a microcontroller to create a very low cost system as shown Figure 1. Voltage regula tors are integrated on-chip which allows for a wide operating supply voltage range from +3.3to +6 V. A standard 4-pin SPI bus is used to communicate with an external microcontroller. Three configurable general purpose I/Os are available. A complete list of the available GPIO functions is shown in "8. Auxiliary Functions"and includes microcontroller clock output, Antenna Diversity, POR, and various interrupts. |
