DS75017A-page 2 Preliminary (c) 2011 Microchip Technology Inc. MRF89XAM9A 1.0 DEVICE OVERVIEW 1.1 The simplified block diagram of the MRF89XAM9A module is shown in Figure 1-1. The module is based on the Microchip Technology MRF89XA Ultra Low-Power Sub-GHz Transceiver Integrated Circuit (IC). The module interfaces to many popular Microchip PIC(R) microcontrollers through a 3-wire serial SPI interface, two chip selects (configuration and data), two interrupts Interrupt Request 0 (IRQ0) and Interrupt Request 1 (IRQ1), Reset, Power and Ground as shown in Figure 1-2. Table 1-1 provides the pin descriptions. The MRF89XAM9A is an ultra low-power sub-GHz surface mount transceiver module with integrated crystal, internal voltage regulator, matching circuitry and PCB antenna. The MRF89XAM9A module operates in the United States/Canada 902-928 MHz ISM frequency band. The integrated module design frees the integrator from extensive RF and antenna design, and regulatory compliance testing, allowing quicker time to market. The MRF89XAM9A module is compatible with Microchip's MiWiTM Development Environment software stacks. The software stacks are available as a free download, including source code, from the Microchip's web site http://www.microchip.com/wireless. Data communication and module configuration are documented in the "MRF89XA Ultra Low-Power, Integrated Sub-GHz Transceiver" (DS70622) Data Sheet. For more information on specific serial interface protocol and general register definitions, refer to the "MRF89XA Data Sheet" and see Section 1.3, Operation for specific register settings unique to the MRF89XAM9A module operation to maintain regulatory compliance. The MRF89XAM9A module has received regulatory approvals for modular devices in the United States (FCC) and Canada (IC). Modular device approval removes the need for expensive RF and antenna design, and allows the user to place the MRF89XAM9A module inside a finished product and not require regulatory testing for an intentional radiator (RF transmitter). To maintain conformance, refer to module settings in Section 3.1.1, MRF89XAM9A SETTINGS for the United States and Section 3.2.1, MRF89XAM9A SETTINGS for Canada.

MRF89XAM9A 3.0 REGULATORY APPROVAL The MRF89XAM9A module has received regulatory approvals for modular devices in the United States and Canada. Modular device approval allows the end user to place the MRF89XAM9A module inside a finished product and not require regulatory testing for an intentional radiator (RF transmitter), provided no changes or modifications are made to the module circuitry. Changes or modifications could void the user's authority to operate the equipment. The end user must comply with all of the instructions provided by the Grantee, which indicate installation and/or operating conditions necessary for compliance. The integrator is still responsible for testing the end product for any additional compliance requirements required with this module installed (digital device emission, PC peripheral requirements, etc.) in the specific country that the end device will be marketed. For more information on regulatory compliance, refer to the specific country radio regulations in the following sections. 3.1 United States The MRF89XAM9A has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C "Intentional Radiators" 15.247 and 15.249 and modular approval in accordance with Part 15.212 Modular Transmitter approval. The MRF89XAM9A module can be integrated into a finished product without obtaining subsequent and separate FCC certification. The MRF89XAM9A module has been labeled with its own FCC ID number, and if the FCC ID is not visible when the module is installed inside another device, then the outside of the finished product into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording as following: Contains Transmitter Module FCC ID: OA3MRF89XAM9A -orContains FCC ID: OA3MRF89XAM9A This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. (c) 2011 Microchip Technology Inc. Requirements for product labeling are given in Part 15.19 Labelling Requirements. The user's manual should include the following statement: 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. 3.1.1 MRF89XAM9A SETTINGS To meet the FCC requirements, the following settings must be observed by the integrator: 3.1.1.1 FSK Modulation The following settings configure the MRF89XAM9A for wideband digital modulation techniques that conform to the requirements of Part 15.247. These settings allow higher radio frequency (RF) output power and greater link budget: * Bit Rate Setting: 50 - 200 kbps - Transmit Power Maximum Setting: 13 dBm * Bit Rate Setting: 2 - 40 kbps - Transmit Power Maximum Setting: 7 dBm * Frequency Deviation Setting: 200 kHz * Data Whitening: On * Lower Frequency Setting: 902.800 MHz * Upper Frequency Setting: 926.500 MHz Preliminary DS75017A-page 17 MRF89XAM9A 3.1.1.2 OOK Modulation The following settings configure the MRF89XAM9A for narrowband operation that conform to the requirements of the part 15.249. The part 15.249 requires a much lower power setting than it is allowed in the part 15.247. These settings are good for applications that require lower transmit power current consumption and shorter transmit distances: * * * * * Transmit Power Maximum Setting: 1 dBm Bit Rate Maximum Setting: 28 kbps Frequency Deviation Setting: 200 kHz Lower Frequency Setting: 902.330 MHz Upper Frequency Setting: 927.500 MHz 3.1.2 RF EXPOSURE All transmitters regulated by FCC must comply with RF exposure requirements. OET Bulletin 65 "Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields" provides assistance in determining whether proposed or existing transmitting facilities, operations or devices comply with limits for human exposure to RF fields adopted by the Federal Communications Commission (FCC). The bulletin offers guidelines and suggestions for evaluating compliance. If appropriate, compliance with exposure guidelines for mobile and unlicensed devices can be accomplished by using warning labels and by providing informations concerning minimum separation distances from transmitting structures and proper installation of antennas. The following statement must be included as a CAUTION statement in manuals and OEM products to alert users of FCC RF Exposure compliance: To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. If the MRF89XAM9A module is used in a portable application (antenna is less than 20 cm from persons during operation), the integrator is responsible for performing Specific Absorption Rate (SAR) testing in accordance with FCC rules 2.1091. 3.1.3 HELPFUL WEB SITES Federal Communications Commission (FCC) http:// www.fcc.gov DS75017A-page 18 Preliminary (c) 2011 Microchip Technology Inc.

MRF89XAM9A SETTINGS To meet Industry Canada (IC) requirements, the following settings must be observed by the integrator: 3.2.1.1 FSK Modulation The following settings configure the MRF89XAM9A for wideband digital modulation techniques that conform to the requirements of RSS-210 Issue 8, Annex 8. These settings allow higher radio frequency (RF) output power and greater link budget. * Bit Rate Setting: 50-200 kbps - Transmit Power Maximum Setting: 13 dBm * Bit Rate Setting: 2-40 kbps - Transmit Power Maximum Setting: 7 dBm * Frequency Deviation Setting: 200 kHz * Data Whitening: On * Lower Frequency Setting: 902.800 MHz * Upper Frequency Setting: 926.500 MHz 3.2.1.2 OOK Modulation The following settings configure the MRF89XAM9A for narrowband operation that conform to the requirements of RSS-Gen Issue 3. RSS-Gen Issue 3 requires a much lower power setting than is allowed in Part RSS210 Issue 8 Annex 8. These settings are good for applications that require lower transmit power current consumption and shorter transmit distances. * * * * * Transmit Power Maximum Setting: 1 dBm Bit Rate Maximum Setting: 28 kbps Frequency Deviation Setting: 200 kHz Lower Frequency Setting: 902.330 MHz Upper Frequency Setting: 927.500 MHz 3.2.2 HELPFUL WEB SITES Industry Canada: http://www.ic.gc.ca/ Preliminary DS75017A-page 19 MRF89XAM9A NOTES: DS75017A-page 20 Preliminary (c) 2011 Microchip Technology Inc.
