1.2 Application MCU connection
Please refer to “Interfacing with ANT General Purpose Chipsets and Modules” and “nRF24AP2 Product
Specification” section 5 “Host Interface”. The following sample designs show the proper electrical
connectivity of an ANT AP2 module to an application microcontroller, using TI MSP430F1232 as example.
1.2.1
Async Mode
AP2 RF Transceiver Module 7 of 19
228 River Avenue, Cochrane, Alberta, Canada T4C 2C1 thisisant.com
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)
1.2.2
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)
8 of 19 AP2 RF Transceiver Module
228 River Avenue, Cochrane, Alberta, Canada T4C 2C1 thisisant.com
1.2.3
Bit Sync Mode
Notes:
• All interface signals are connected directly to I/O pins on the microcontroller.
• SCLK and SEN need to be on an interrupt capable I/O pin on the microcontroller. (Interrupt pins
located on Port 1&2 on the MSP430F1232)
1.3 Mounting Guideline
Refer to the recommended footprint drawing in section 4.
It is best to position the AP2 module so that the copper keepout area is on the edge or over hanging the edge of the
mating PCB. If the copper keepout layer is completely within the boundaries of the PCB, the ground plane should not
fully surround the copper keepout. If this is not possible, the copper keepout should be made much larger to prevent RF
degradation. The ground plane is recommended to extend to the full size of the mating PCB, with the exception of the
copper keepout.
To connect to M5IB type of AP2 module, the mating socket is Molex 52991-0208.

1.4 Reflow Guideline
Follow the guideline below if AP281M4IB modules go through reflow oven.
Peak solder joint/pad temperatures exceeding 240ºC are not recommended. If possible, pre-heat the
assembly within the oven profile for ~30 seconds at ~150 ºC. Follow the solder paste manufacturer’s
recommendations, especially regarding temperature ramp rate and the time above liquidus.

Usable band is determined by local regulations
Maximum output power with 0dBm output power setting. Antenna load impedance = 15Ω +j88Ω
Time of maximum Tx only current is typical 300µs and maximum 350µs
Time of maximum current consumption in RX is typical 500µs and maximum 1ms
Transmit only operation provides no ANT channel management across the air channel and is not recommended for
normal operation
Asynchronous serial messages contained two 0 pad bytes, thereby adding to the average current. Values will be
lower without the use of 0 pad bytes
Does not include base current. See current calculation examples below
Value calculated assuming that external 32.768 kHz crystal oscillator is used
Example Current Calculations:
1. Transmit channel with Broadcast data at 4Hz with a bit synchronous serial interface and external source
of 32.768kHZ clock.
I
ave = (IMsg_TR_BitSync * Message_Rate) + IBase_32KXO

= (36µA/message * 4messages) + 3.0 µA
= 147 µA
2. Receive channel with Acknowledged data at 2Hz with an asynchronous serial interface at 57600 baud
and internal synthesized 32.768kHZ clock.
I
ave = (IMsg_Ack_Rx_57600 * Message_Rate) + IBase_32kSynt
= (22 µA/message * 2messages) + 100 µA
= 144 µA
