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.

Approvals and Usage The  A2530R24A  and  A2530R24C  have  been  designed  to  meet  most  national  regulations  for worldwide ISM band  use.  In  particular, the  radio modules  have been  certified to  the  following standards.  2.1.  Product Approvals 2.1.1.  USA (Federal Communications Commission, FCC) The A2530R24A and A2530R24C modules have been tested to comply with FCC CFR47 Part 15 sub-part C “Intentional Radiators” standard. The modules meet the requirements for modular transmitter approval as  detailed in  FCC  public  notice DA  00-1407 released in  June  26,  2000. The modular transmitter approval eliminates the need to re-perform costly ‘intentional radiator’ testing when submitting an end product for certification. (15.19a3)  The  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. Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.  2.1.1.1.  FCC Labeling Requirements The A2530R24A and A2530R24C modules have been labeled with their own FCC ID number and  if  the  FCC  ID  is  not  visible  when  the  module  is  installed  inside  another  device,  then  the outside  of  the  finished  product  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: X7J-A11113001 -or- Contains FCC ID: X7J-A11113001 This device 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.
Page 10 of 30    A2530R24x – User’s Manual     Release Date 04/26/12     2.1.1.2.  End User Manual The end user manual should include the following statement: This equipment 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  or more 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.  2.1.1.3.  RF Exposure All transmitters regulated by FCC must comply with RF exposure requirements. OET Bulletin 65 “Evaluating  Compliance  with  FCC  Guidelines  for  Human  Exposure  to  Radio  Frequency Electromagnetic  Fields”  provides  assistance  in  determining  whether  proposed  or  existing transmitting  facilities,  operations  or  devices  comply  with  limits  for  human  exposure  to  Radio Frequency (RF) fields adopted by the Federal Communications Commission (FCC). The bulletin offers guidelines and suggestions for evaluating compliance. If appropriate, compliance with exposure guidelines for mobile and unlicensed devices can be accomplished by the use of warning labels and by providing users with information concerning minimum separation distances from transmitting structures and proper installation of antennas. The  following  statement  must  be  included  as  a  CAUTION  statement  in  manuals  and  OEM products to alert users of FCC RF Exposure compliance: To satisfy FCC 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. 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 FCC rules 2.1093.
A2530R24x – User’s Manual    Page 11 of 30 Release Date 04/26/12       2.1.2.

RF Exposure All transmitters regulated by IC must comply with RF exposure limits as set forth in RSS-102, Issue  4,  section  4,  “Exposure  Limits”.  Furthermore RSS-102,  Issue  4,  Section  2  “Certification Requirements”, provides assistance in determining the specific requirements for compliance. If appropriate,  compliance  with  exposure  guidelines  for  mobile  and  unlicensed  devices  can  be accomplished by the use of warning labels and by providing users with information concerning minimum separation distances from transmitting structures and proper installation of antennas.  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

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.

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
