ANT C7 RF Transceiver Module Page 7 of 20 thisisant.com 1.3 Application MCU connection Please refer to “Interfacing with ANT General Purpose Chipsets and Modules” and “CC2571 Datasheet”. The following sample designs show the proper electrical connectivity of an ANT C7 module to an application microcontroller, using TI MSP430F1232 as example. 1.3.1 Async Mode Notes:  Module RXD and TXD connected directly to hardware USART of microcontroller.  Switches on baud rate selection pins (BR1, BR2 and BR3) are for ease of use only. They can be connected directly to the logic level of interest.  RTS can be connected to an interrupt pin for convenience in some applications. (Interrupt pins located on Port 1&2 on the MSP430F1232)

Page 8 of 20 ANT C7 RF Transceiver Module thisisant.com 1.3.2 Byte Sync Mode Notes:  Module SOUT, SIN, and SCLK connected directly to hardware USART of microcontroller.  SEN needs to be on an interrupt capable I/O pin on the microcontroller. (Interrupt pins located on Port 1&2 on the MSP430F1232)

ANT C7 RF Transceiver Module Page 11 of 20 thisisant.com 2. Regulatory Approval (In process. Not completed) The ANT C7 module has received regulatory approvals in the United States (FCC), Canada (IC), Europe (ETSI), Australia and New Zealand. Such approvals allow the user to place the module inside a finished product and, in usual case, not require regulatory testing for an intentional radiator, provided no changes or modifications are made to the module circuitry. This does not preclude the possibility that some other form of authorization or testing may be required for the finished product. 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. 2.1 United States The ANT C7 module 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 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. The C7 module 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.. The C7 module does not contain any user-serviceable parts. Unauthorized repairs or modifications could result in permanent damage to the equipment, and void your warranty and your authority to operate this device under Part 15 regulations. The C7 module is labelled with its own FCC ID, O6R1823 (note: First Character is the letter O, not the # 0.) If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: O6R1823” or “Contains FCC ID: O6R1823”. Any similar wording that expresses the same meaning may be used. 2.2 Industry Canada Compliance This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. (Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.) To comply with Industry Canada regulations, it is required that product containing the C7 module display a label referring to the enclosed module. This exterior label can use wording similar to the following: “Contains IC: 3797A-1823”

Page 16 of 20 ANT C7 RF Transceiver Module thisisant.com While these current values include the contribution of the radio and the serial interface they do not include the base (idle) current. To calculate the average current consumption of for a specific message rate please see the sample calculation below. AverageBurstCurrentFor practical purposes power consumption in burst mode is reported as an average current when bursting at a specific bit rate and using a specific serial interface. Please note that the bit rate of the burst is a function of the serial communication. The table below lists the continuous average current consumption while bursting. Measured with TA = 25°C and VCC = 3 V. Output power set at 0dBm Symbol Description Average Current Units Iburst_20kbps_byte Continuous bursting at 20kbps in byte synch mode 9.0 mA Iburst_7.5kbps_bit Continuous bursting at 7.5kbps in bit synch mode 8.2 mA Iburst_20kbps_57600_async Continuous bursting at 20kbps in 57600 baud async mode 8.7 mA Iburst_20kbps_50000_async Continuous bursting at 20kbps in 50000 baud async mode 8.4 mA Iburst_13.8kbps_38400_async Continuous bursting at 13.8kbps in 38400 baud async mode 7.9 mA Iburst_8.4kbps_19200_async Continuous bursting at 8.4kbps in 19200 baud async mode 7.0 mA 3.6 Calculating the Average Current Consumption and Battery Life The average current for a particular application will be a function of the message period, type and serial interface. By using the values listed in the tables above, the average current can be calculated using the following formula: IAVE = (IMSG X RMSG) + IIDLE where: IAVE – Average current consumption. IMSG – Current per message IIDLE – Base or idle current For example, given an ANT node that transmits broadcast data over a bi-directional channel at 0.5Hz using a byte synchronous serial interface, the continuous average current can be calculated as follows: IAVE = (49 X 0.5) + 0.91 = 25.41µA To calculate the expected battery life of a system, the battery capacity and usage model must also be considered. The following formula can be used (please note that this considers the current consumed by the ANT part of the system only): TBAT CBAT · TOperation CycleTActive· IAveTIdle·IIdle

ANT C7 RF Transceiver Module Page 17 of 20 thisisant.com where: TBAT – Expected battery life of the system CBAT – Battery capacity TOperation_Cycle – Operation cycle over which usage is calculated TActive – Active time in transmit mode IAve – Average current consumption in active mode TIdle – Time in non-active mode (off) IIdle – Average current in idle mode For example, for a system using a CR2032 coin cell batter transmitting at 0.5Hz broadcast for 1 hour per day, the battery life of the system can be calculated as follows: TBAT 220mAh· 24h1h· 25.41μA23h·0.91μA 12.7 years Please note that the above example assumes that 100% of the battery capacity can be dedicated to the ANT portion of the system.
