AX5051 Programming Manual APPLICATION NOTE
■AX5051 is a true single chip low-power CMOS transceiver primarily for use in SRD bands. The on-chip transceiver consists of a fully integrated RF front-end with modulator, and demodulator. Base band data processing is implemented in an advanced and flexible communication controller that enables user friendly communication via the SPI interface.
●Connecting the AX5051 to a Micro-Controller
■Th AX5051 can easily be connected to any micro-controller. The micro-controller communicates with the AX5051 via a register file that is implemented in the AX5051 and that can be accessed serially via an industry standard Serial Peripheral Interface (SPI) protocol.
■Reset can be performed via a dedicated signalling line or via the register file. Therefore, and due to an integrated power-on-reset (POR) block this signal is optional.
■The AX5051 sends and receives data via the SPI port in frames. This standard operation mode is called frame mode.
■In frame mode, the internal communication controller performs frame delimiting, and data is received and transmitted via a 4 level x 10 bit FIFO, accessible via the register file. Figure 1 shows the corresponding diagram. Connecting the interrupt line is highly recommended, though not strictly required.
