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.

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

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.
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.
