A2530R24x – User’s Manual Page 5 of 30 Release Date 04/26/12 1. Overview The A2530R24A and A2530R24C are surface mount transceiver modules. The A2530R24A has an integral antenna, whereas the A2530R24C utilizes an external antenna through a U.FL connector (see Table 1). These modules incorporate a crystal, the required RF matching and filtering for regulatory compliance as well as filtering on all digital lines for noise reduction and sensitivity. They operate in the global non-licensed 2.4GHz ISM/SRD frequency band. The modules are ideal for achieving low power, long range wireless connectivity without having to deal with extensive protocol, RF, antenna design and regulatory compliance, and provide quick time to market. They are 100% tested to provide consistent performance. The A2530R24A and A2530R24C modules have received regulatory approvals for modular devices in the United States (FCC), Canada (IC) and Europe (ETSI). The modular approval allows the end user to place either an A2530R24A or an A2530R24C with an approved antenna inside a finished product without having to perform costly regulatory testing for an intentional RF radiator. Section 2.3 has information on the requirements for the end user/integrator to fulfill in order to use the modules without intentional radiator regulatory testing. The A2530R24A and A2530R24C are based on the CC2530 SoC transceiver from Texas Instruments (TI). The CC2530 combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 microcontroller unit (MCU), in-system programmable flash memory, 8-KB RAM, and many other powerful features. The CC2530 has various operating modes, making it highly suited for systems where ultralow power consumption is required. Short transition times between operating modes further ensure low energy consumption. All control lines are provided at module level for full control of the operation. Please see the datasheets for CC2530 (www.ti.com) for how to operate, program and control these modules. The A2530R24A and A2530R24C modules measure 11 mm x 19 mm x 2.5 mm. The modules are footprint compatible with each other. 1.1. A2530R24A The A2530R24A has an integral antenna, providing high efficiency and near omni-directional radiation pattern. This approach offers the lowest system cost when the application allows collocation of radio and antenna. 1.2. A2530R24C The A112530E24C has a compact antenna connector that allows for locating the antenna away from the module due to form/function or in order to exit a metal enclosure, see Figure 6 - Figure 7 for more information on antenna location and enclosure considerations.

They can be used to implement a variety of networks, including point to point, point to multi-point, peer to peer and mesh networks. Figure 1 and Figure 2 show the functionality of A2530R24A and A2530R24C, respectively. Both modules operate in a similar manner except the antenna part where A2530R24A communicates through a built-in antenna, and A2530R24C communicates through an external antenna attached to a U.FL antenna port. The description of the functional blocks shown in Figure 1 and Figure 2 is given as follows:
A2530R24x – User’s Manual Page 7 of 30 Release Date 04/26/12  Antenna o The antenna couples energy between the air and the module. The integral antenna and the external monopole antenna, both centered at 2441.75 MHz, provide a near omni-directional antenna pattern with high efficiency such that the application will work equally well in any direction. Note that the end radiation pattern depends not only on the antenna, but also the ground plane, enclosure and installation environment.  Matching & Filtering o The matching provides the correct loading of the transmit amplifier to achieve the highest output power as well as the correct loading for the receive LNA to achieve the best sensitivity. o Filtering removes spurious signals to comply with regulatory intentional radiator requirements, provides reduced susceptibility to power supply and digital noise, and filters out RF and high frequency noise from the communication data and control link.  TX/RX Chain o TX/RX chain handles transmitting and receiving of the communication data based on the radio register settings. It involves the coordination of several blocks including modulator, demodulator, AGC control, frequency synthesizer and frame control.  Crystal o Crystal oscillator provides the necessary clock reference for the whole module operation. The A2530R24A and A2530R24C modules use a 32 MHz crystal.  Power Management o Power management ensures a stable supply for the internal functions, as well as providing means for a low power sleep mode.  CPU and Memory o The 8051 CPU core used in the CC2530 device is a single-cycle 8051-compatible core. It has three different memory-access buses (SFR, DAT and CODE/XDATA) with single-cycle access to SFR, DATA, and the main SRAM. It also includes a debug interface and an 18-input extended interrupt unit. o The memory arbiter connects the CPU and DMA controller with the physical memories and all peripherals through the SFR bus. o The 8-BK SRAM maps to the DATA memory space and to parts of the XDATA memory spaces. This is an ultralow-power SRAM that retains its contents even when the digital part us powered off. o 256 KB flash block provides in-circuit programmable non-volatile program memory for the device, and maps into the CODE and XDATA memory spaces. In addition to holding the program code, it also allows the application to save data that must be preserved such that it is available after restarting the device.  I/O Controller o The I/O controller is responsible for all general-purpose I/O pins. The CPU can configure whether peripheral modules control certain pins or they are under software control, and if so, whether they are configured as input or output.

The following statement must be included as a CAUTION statement in manuals and OEM products to alert users of IC RF Exposure compliance: Notice: To satisfy IC 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. Avis: Pour répondre à la IC d'exposition pour les besoins de base et mobiles dispositifs de transmission de la station, sur une distance de séparation de 20 cm ou plus doit être maintenue entre l'antenne de cet appareil et les personnes en cours de fonctionnement. Pour assurer le respect, l'exploitation de plus près à cette distance n'est pas recommandée. L'antenne (s) utilisé pour cet émetteur ne doit pas être co-localisés ou fonctionner conjointement avec une autre antenne ou transmetteur. If the A2530R24A and A2530R24C modules are used in a portable application (antenna is less than 20 cm from persons during operation), the integrator/OEM is responsible for performing Specific Absorption Rate (SAR) testing in accordance with IC rules and methods of RSS-102. 2.1.3. Europe (Conformité Européenne, ) The A2530R24A and A2530R24C modules have been certified for use in European countries. The following tests have been performed and the module found to be compliant to the requirements:  Test standard ETSI EN 300 328 V1.7.1 (2006-10)  Maximum Isotropic Radiated Power (Normal and Extreme Conditions)  Maximum e.i.r.p. Spectral Density  Frequency Range (Normal and Extreme Conditions)  Transmitter Spurious Emissions
Page 14 of 30 A2530R24x – User’s Manual Release Date 04/26/12  Receiver Spurious Emissions  Electro-Static Discharge and RF Immunity (ETSI EN 301 489-17)  RF Exposure (ETSI EN 62311:2008)  Safety (IEC 60950-1:2005 and EN 60950-1:2006) A helpful document that can be used as a starting point in understanding the use of short range devices (SRD) in Europe is the European Radio Communications Committee (ERC) Recommendation 70-03 E, downloadable from the European Radio Communications Office (ERO) http://www.ero.dk. The end user is responsible for ensuring compliance with harmonized frequencies and labeling requirements for each country the end device is marketed and sold. For more information see:  Radio And Telecommunications Terminal Equipment (R&TTE) http://ec.europa.eu/enterprise/rtte/index_en.htm  European Conference of Postal and Telecommunications Administrations (CEPT) http://www.cept.org/  European Telecommunications Standards Institute (ETSI) http://www.etsi.org/  European Radio Communications Office (ERO) http://www.ero.dk/ 2.2. Potential Interference Sources The radio modules operate in the unlicensed ISM band, in which there are many other applications e.g. WLAN, Bluetooth® and microwave ovens. This can cause interference that may, in certain conditions, prohibit radio communication. The user is encouraged to implement a number of channels and to alternate between those channels based on one of the below methods.  Sense if a particular channel is clear prior to transmitting (clear channel assessment)  Pseudo Random channel change  Select channels with the least interference (site survey) Some of the most common interferences are listed below. 2.2.1. WLAN Wireless Local Area Networks (WLANs) are divided into a number of overlapping channels. Figure 3 below shows the channels used by WLAN; for the US and Canada, only channels 1-13 may be used. Predominantly, channels 1, 6 and 11 are used to achieve non-overlapping channels. The user is therefore encouraged to select a channel scheme that also has channels falling in between, or entirely outside, WLAN channels. Using a detection scheme (clear channel assessment) will enable the user to find channels with minimal interference from WLAN devices.
A2530R24x – User’s Manual Page 15 of 30 Release Date 04/26/12 Figure 3 WLAN channels 2.2.2. Bluetooth® Bluetooth® divides the 2.402-2.480 GHz band into 79 channels, each of which is 1MHz wide. However, since Bluetooth® changes channels rapidly (up to 1600 times a second), it is unlikely to cause continuous interference in a specific channel and can be overcome by implementing a simple acknowledge/retransmit functionality. 2.2.3. Microwave ovens A typical microwave oven uses a self-oscillating magnetron with a duty cycle below 50%, because the tube is completely off for half of every AC mains cycle (8.33 ms in 60 Hz countries and 10 ms in 50 Hz countries). The frequency of the microwave oven changes cyclically within each AC mains synchronized on period, and is generally not predictable. The user is encouraged to have packet transmission durations less than half the AC mains period and implement an acknowledge/retransmit method. 2.2.4. Other Interference Systems similar to the user’s system may also exist within range and may also be a source of interference; some typical applications to consider are:  Alarm systems o These typically use low duty cycles and are therefore easy to avoid using acknowledge/retransmit methods  Car alarms (internal motion sensors)  Video surveillance o These are typically operated on a fixed channel, determined at installation time and can be avoided by using clear channel assessment. It may be useful to change the channel used by the video surveillance equipment also, if possible. 2.2.5. Time critical data If the user requires specific time critical data throughput that cannot tolerate the delays of potentially many re-transmissions, the user is encouraged to implement an environment-aware algorithm that periodically monitors/scans the frequency band and maintain a list of “best available” channels.
Page 16 of 30 A2530R24x – User’s Manual Release Date 04/26/12 2.3. Approved Usage The A2530R24A and A2530R24C modules have been approved for use in the US, Canada and Europe. The user is encouraged to use minimum power required to establish a link, thus minimizing interference. Changes or modifications to the module and/or operation outside the limits are prohibited and could void the user’s authority to operate the modules. 2.3.1. USA and Canada Within the USA and Canada, the A2530R24A and A2530R24C modules have been approved for use as digitally modulated transmitters, for which they conform to the BW (a minimum of 500 kHz 6-dB BW for US, a maximum BW of 0.5% of the carrier frequency for Canada), power spectral density (max of 8 dBm / 3 kHz), total output power (max of 1W including the antenna gain) and spurious radiation (harmonics and others including the restricted bands) requirements. Table 2 shows approved frequencies of operations with the corresponding maximum output power values and PA_Table register settings. These modules must be operated at or below the indicated power levels. Using the modules with higher power levels are prohibited, and will void the user’s authority to operate the modules under current FCC/IC certification. Table 3 shows available power levels from the device along with the corresponding PA_Table register settings. Users are encouraged to use minimum power required to establish a link, thus minimizing interference and current consumption.

Power Supply Considerations Noise on the power supply line reduces the sensitivity of a receiver and can modulate onto a transmitters signal, both of which causes a degradation of link quality and hence a reduction in range. The A2530R24A and A2530R24C modules have integral noise reduction from power supply to the internal AVDD and DVDD pins, consisting of ferrite beads and decoupling capacitances. This arrangement will take care of most supply voltage noise. For optimal performance in particular noisy environments (switching regulators, motor controls, etc.) it may be necessary to add additional noise reduction means, which can consist of a low noise LDO or additional LC filtering. Note that if operated from a battery source there is no need for additional noise reduction. Also note that if the noise source can be synchronized to be off whenever the module is transmitting or receiving then that will also suffice.

A2530R24x – User’s Manual Page 25 of 30 Release Date 04/26/12 4.3. Soldering AIR Modules may be mounted either manually (for prototyping or low volume production), or automatically for high-volume production. A no-clean tin/silver/copper (SAC) solder is recommended, however lead based no-clean pastes may also be used. CAUTION: AIR Modules are designed for no-clean fluxes only. DO NOT use water-based fluxes that require aqueous cleaning after solder. Spot cleaning with a flux remover and toothbrush may be performed with care. 4.3.1. Manual Mounting Procedure The recommended soldering method is reflowing of a paste solder on a hot plate. This method works provided the bottom of the board where the AIR module is to be mounted is accessible, and there are no bottom-side components in the way. An aluminum or copper block may be placed on the hot plate surface to transfer heat to a localized area on the board where the AIR module is mounted - Set the hot plate to the reflow temperature solder manufacturer’s recommended - Apply solder paste to the pads on the board receiving the AIR module - Place the AIR module carefully onto the dispensed solder - Using tweezers or another holding device, carefully place board with AIR module onto the hot plate surface (or metal block) - Apply heat until reflow occurs, per solder paste manufacturer’s recommendations - Carefully remove the board and place on a heat-resistant surface to cool - Check assembly electrically to confirm there are no opens or shorts
