MC1320x RF Daughter Card

User’s Guide

1 Introduction

The MC1320x RF Daughter Card (1320xRFD-A00) is used in conjunction with a microcontroller
development board for RFIC evaluation, code development, and system evaluation. The RF Daughter
Card interfaces directly to the M68EVB908GB60, RG60 and QG60 HCS08 family Microcontroller
Development Boards and to the M52235 EVB 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 MC1320x 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 an onboard PCB
antenna. Also, there is an SMT jumper that can be relocated, which will redirect the RF interface to an
on-board 50 ohm connector. The SMA connector can be used with standard coax cables for testing
purposes. Figure 1-1 shows the RF Daughter Card.

Safety Information

2 Safety Information

Any modifications to this product may violate the rules of the Federal Communications Commission and
make operation of the product unlawful.

47 C.F.R. 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.

Daughter Card Description

5 Daughter Card Description

As shown in Figure 5-1 and Figure 8-1, connector J101 is the main interface to the GB60 Development
Board. The interface connections described in Section 5.1, “Development Board Interconnects”, fall under
the following three broad categories:

1. Serial Peripheral Interface (SPI)

2. Control

3. Power

Figure 1-2 shows how the RF Daughter Card is mounted on the GB60 Development Board.

NOTE

Ensure that zero ohm resistor R104 is in place on the MC1320x Daughter
Card. As of this release, previous versions of the MC1320x Daughter Card
may not have R104 inserted.

NOTE

J101 Pin 1 of the MC1320x must to be connected to GB_POR T Pin 1 of the
GB60 Development Board.

As shown in Figure 5-1 and Figure 8-1, connector J102 is the main interface to the M52235 Development
Board. Figure 1-3 shows how the RF Daughter Card is mounted on the M52235 Development Board.

NOTE

J102 Pin 1 of the MC1320x must be connected to MCU_POR T Pin 1 on the
M52235 Development Board.
