4 / 28 page MC13201 Technical Data, Rev. 1.1, 4 Freescale Semiconductor 3 Block Diagrams Figure 1 shows a simplified block diagram of the MC13201 which is an 802.15.4 Standard compatible transceiver that provides the functions required in the physical layer (PHY) specification. Figure 1. 802.15.4 modem Simplified Block Diagram Figure 2 shows the basic system block diagram for the MC13201 in an application. Interface with the transceiver is accomplished through a 4-wire SPI port and interrupt request line. The media access control (MAC), drivers, and network and application software (as required) reside on the host processor. The host can vary from a simple 8-bit device up to a sophisticated 32-bit processor depending on application requirements. Figure 2.
