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)
