Block Diagrams

Figure 1 shows a simplified block diagram of the MC13192 which is an 802.15.4 Standard compatible

transceiver that provides the functions required in the physical layer (PHY) specification.

Figure 2 shows the basic system block diagram for the MC13192 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.
