Freescale Semiconductor User’s Guide Document Number: MC13192RFCUG Rev. 1.2, 09/2006 MC13192 RF Daughter Card User’s Guide 1 Introduction The MC13192 RF Daughter Card (13192RFC-A00) is used in conjunction with a microcontroller development board for RFIC evaluation, code development, and system evaluation. It interfaces directly to the M68EVB908GB60 HCS08 family Microcontroller Development Board but it can be adapted to other boards that offer access to the MCU input/output ports. The RF Daughter Card is configured with all the off-chip circuitry required for functional performance of the MC13192 RF data modem except the MCU. The MCU interface required by the RFIC is pinned out at the edge of the card using standard header pins. The RF interface is accomplished through SMA connectors for the TX and RX ports. The SMA connectors can be connected to test equipment using coax cables for testing or connected to screw-on antennas (two provided) for testing purposes. Figure 1-1 shows the RF Daughter Card with the two detachable dipole antennas. Figure 1-1. MC13192 RF Daughter Card with Antennas © Freescale Semiconductor, Inc., 2004, 2005, 2006.

Sec. 15.21 This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. 47 C.F.R. Sec.15.105(b) This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. The antenna(s) used for this equipment must be installed to provide a separation distance of at least 8 inches (20cm) from all persons. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: • This device may not cause harmful interference. • This device must accept any interference received, including interference that may cause undesired operation.

Figure 4-1. RF Daughter Card PCB (Top View) Figure 4-2 shows the bottom side of the RF Daughter Card PCB. Figure 4-2. RF Daughter Card PCB (Bottom View) As shown in Figure 1-2 and Figure 4-1 , connector J1 is the main interface to the GB60 Development Board. The interface connections described in Section 4.2, “Connections”, fall under the following three broad categories: 1. Serial Peripheral Interface (SPI) 2. Control 3. Power MC13192 RF Daughter Card, Rev. 1.2 4 Freescale Semiconductor Daughter Card Description 4.1 SPI Connections J1 Pins 35 through 38 provide the following four wire SPI interface: • MOSI • SPICLK • CE • MISO The MC13192 always functions as a slave device. SPI operation is described in detail in the MC13192 Data Sheet and/or MC13192 Reference Manual. 4.2 Connections The following sections describe the interconnects for the GB60 Development Board. 4.2.1 • • • Control Connections J1 Pin 19 is the IRQ line from MC13192. Connection to the MCU depends on how the MCU services interrupts. J1 Pin 31, RXTXEN, allows the MCU to initiate transceiver functions. J1 Pin 34, the ATTN line, allows the MCU to wake up the MC13192 from Doze or Hibernate low power modes. NOTE RXTXEN and ATTN are also available at header J2 for manual control. • • • • • • 4.2.2 J1 Pin 24 provides the MC13192 CLKO to the MCU when a jumper is installed at J4. J1 Pin 32 interfaces with the MCU to provide a Reset to the MC13192 and header J7 controls the functionality. When Pin 2 and Pin 3 of J7 are shunted, the MC13192 and the MCU can be reset simultaneously. When Pin 1 and Pin 2 of J7 are shorted, the MCU will reset the MC13192. Pin 5 and Pin 22 of J1 provide a wake up function to the MCU when a shunt is installed at J3. Pin 13 and Pin 14 of J1 provide access to MC13192 GPIO1 and GPIO2 ports. Power Connections J1 Pin 39 provides the supply voltage to the RF Daughter Card. Voltage on this line should not exceed 3.6 VDC and the nominal supply should not exceed 3.4 VDC. J1 Pin 40 is ground. 4.2.3 Non-MCU connections Header J2 provides connections to a number of MC13192 contacts for non-MCU connections. As already stated, the RXTXEN and ATTN lines are available at J2 for external control using switches or other hardware. The MC13192 GPIO are also available for interface to external hardware.

The SMAC jumper settings on the board can now be ignored because as of this release, the SMAC and 802.15.4 MAC use the same settings. 6 Bill of Materials and Schematic Table 6-1 shows the RF Daughter Card bill of materials (BOM).
