Page 4 of 20 ANT C7 RF Transceiver Module ANT™ Overview ANT™ is a practical wireless sensor network protocol running on 2.4 GHz ISM band. Designed for ultra low power, ease of use, efficiency and scalability, ANT easily handles peer-to-peer, star, tree and practical mesh topologies. ANT provides reliable data communications, flexible and adaptive network operation and cross-talk immunity.

ANT C7 RF Transceiver Module 1.3 Page 7 of 20 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.

Page 10 of 20 1.3.4 ANT C7 RF Transceiver Module External Memory Connection The ANTC782 has ANT-FS Client functionality embedded directly on the module This includes the over the air ANTFS protocol extension and the required file system utilities to manage stored data in non-volatile storage. This allows the user to connect an EEPROM directly to the ANTC782 module. Raw files can be sent and managed by the ANTC782 and downloaded over ANT-FS as desired.

ANT C7 RF Transceiver Module 2. Page 11 of 20 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.

Page 16 of 20 ANT C7 RF Transceiver Module 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.
