1. Overview
The A2530E24A and A2530E24C are surface mount modules integrating Texas Instruments’
(TI) CC2530 system-on-chip (SoC) transceiver with the CC2591 PA/LNA device for increased
range. The A2530E24A has an integral antenna, whereas the A2530E24C 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 A2530E24A and A2530E24C 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 A2530E24A or an A2530E24C 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 A2530E24A and A2530E24C are based on the CC2530 SoC transceiver and the CC2591
range extender chips, both 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 and
CC2591 (www.ti.com) for how to operate, program and control these modules.
The A2530E24A and A2530E24C modules measure 11 mm x 19 mm x 2.5 mm. The modules
are footprint compatible with each other.
1.1. A2530E24A
The A2530E24A 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. A2530E24C
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.

1.4. Theory of Operation
The A2530E24A and A2530E24C modules operate in the global 2.4 GHz ISM/SRD frequency
band. 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 A2530E24A and A2530E24C, respectively. Both
modules operate in a similar manner except the antenna part where A2530E24A communicates
through a built-in antenna, and A2530E24C communicates through an external antenna
attached to a U.FL antenna port.

A2530E24x –User’s Manual Page 7 of 30
Release Date 11/01/12
The description of the functional blocks shown in Figure 1 and Figure 2 is given as follows:
Antenna
oThe 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
oThe 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.
oFiltering 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.
Range Extender
oThe range extender serves as an RF front-end for low power transceiver. It
contains PA, LNA, switches, RF-matching and a balun.
TX/RX Chain
oTX/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
oCrystal oscillator provides the necessary clock reference for the whole module
operation. The A2530E24A and A2530E24C modules use a 32 MHz crystal.
Power Management
oPower management ensures a stable supply for the internal functions, as well as
providing means for a low power sleep mode.
CPU and Memory
oThe 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.
oThe memory arbiter connects the CPU and DMA controller with the physical
memories and all peripherals through the SFR bus.
oThe 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 is powered off.
o256 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

Page 8 of 30 A2530E24x –User’s Manual
Release Date 11/01/12
oThe 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.

2. Approvals and Usage
The A2530E24A and A2530E24C 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 A2530E24A and A2530E24C 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 A2530E24A and A2530E24C 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-A11091301
-or-
Contains FCC ID: X7J-A11091301
This device complies with Part 15 of the FCC Rules.

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 A2530E24A and A2530E24C 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.

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

Page 16 of 30 A2530E24x –User’s Manual
Release Date 11/01/12
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.
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.

A2530E24x –User’s Manual Page 17 of 30
Release Date 11/01/12
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
oThese typically use low duty cycles and are therefore easy to avoid using
acknowledge/retransmit methods
Car alarms (internal motion sensors)
Video surveillance
oThese 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.
2.3. Approved Usage
The A2530E24A and A2530E24C 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 A2530E24A and A2530E24C 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.

2.3.2. Europe
For Europe, the maximum power is 100mW with a maximum spectral power density of
10mW/MHz. In order to meet the power spectral density requirements, the A2530E24A and
A2530E24C modules should have lower output power levels.
Table 4 shows approved frequencies of operations with the corresponding maximum output
power values and PA Table register settings. Please refer Table 3 for the available power levels
from this module.

3.3. Pin Out
The A2530E24A and A2530E24C radios share a common pin-out and foot print, thus enabling
the use of the same application PCB layout for US/Europe and low power (short range) versus
higher power (long range). Below the footprint is shown.
