CC2538
RADIO MODULE
User Manual
The CC2538 is the ideal SoC for high-performance ZigBee applications. It
combines a powerful ARM Cortex®-M3based MCU system with up to 32K on-chip RAM
and up to 512 K on-chip flash with a robust IEEE 802.15.4 radio.
This enables it to handle complex network stacks with security, demanding
applications, and over-the-air download. Thirty-two GPIOs and serial
peripherals enable simple connections to the rest of the board. The powerful
security accelerators enable quick and efficient authentication and encryption
while leaving the CPU free to handle application tasks.
The low-power modes with retention enable quick startup from sleep and minimum
energy spent to perform periodic tasks. For smooth development, the CC2538xFnn
includes a powerful debugging system and a comprehensive driver library. To
reduce the application flash footprint, CC2538xFnn ROM includes a utility
function library and a serial boot loader.

FCC regulatory compliance statement
§15.19 Statement
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.
§15.21 Information to user
Warning: Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
List of applicable FCC rules:
47 CFR Part 15, Subpart C 15.203
47 CFR Part 15, Subpart C 15.205
47 CFR Part 15, Subpart C 15.207

Summarize the specific operational use conditions
This module can be used in IOT devices, the input voltage to the module is
nominally 5V. Only the embedded integral antenna is allowed. Any other
external antenna is prohibited.
Limited module procedures
This module is not a limited module.
Trace antenna designs
The antenna is not a trace antenna.
RF exposure considerations
This Module complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
a minimum distance of 20cm between the radiator and your body. This
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
Antennas
If you desire to increase antenna gain and either change antenna type or use
same antenna type certified, a Class II permissive change application is
required to be filed by us, or you (host manufacturer) can take responsibility
through the change in FCC ID
(new application) the procedure followed by a Class II permissive change
application.
Label and compliance information
Please notice that if the FCC identification number is not visible when the
module is installed inside another device, then the outside of the device 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 FCC ID: 2AZ89C2538” any similar wording that expresses the same
meaning may be used.
§ 15.19 Labelling requirements shall comply on the end-user device.
Labeling rules for a special device, please refer to §2.925, § 15.19 (a)(5),
and relevant KDB publications. For E-label, please refer to §2.935.
Information on test modes and additional testing requirements
The OEM integrator is responsible for ensuring that the end-user has no manual
instruction to remove or install-module.
The module is limited to installation in mobile applications, a separate
approval is required for all other operating configurations, including
portable configurations with respect to §2.1093 and different antenna
configurations.
Additional testing, Part 15 Subpart B disclaimer
This modular transmitter is only FCC authorized for the specific rule parts
listed on our grant, host product manufacturer is responsible for compliance
to any other FCC rules that apply to the host not covered by the modular
transmitter grant of certification. Host manufacturer in any case shall ensure
host product that is installed and operating with the module is in compliance
with Part 15B requirements.
Please note that For a Class B or Class A digital device or peripheral, the
instructions furnished the user manual of the end-user product shall include
statement set out in §15.105 Information to the user or such similar statement
and place it in a prominent location in the text of host product manual.

Sample Operation Description Sample
Operation Description
For Class B
Note: 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.
The 32MHZ Hz crystal oscillator drives the base of Q1.
The modulation is provided by IC FA128-32F20X-K3128. The output of has the
matching network consisting of balun 2450BM14G0011 that limits the harmonic
content and affects the proper coupling of the antenna to the output stage.
Antenna, Ground and Power Source
The antenna consists of a 2.4GHz Meander line SWRU120C antenna.
Antenna gain: 1.1 to 3.3 dBi.
There is no external ground connection. The ground is only that of the printed
circuit board.
Electric current is supplied by Input VCC;
Output: 3.3 Vd.c..
Operation Descriptions
The transmitter is a Portable Wireless Music System operating at the
2400-2483.5MHz band. The transmitter is powered by 3.3 Vd.c and the
transmitting frequency is crystal controlled. The operation is achieved by
different combinations of form pulse modulating signals on the 2400MHz carrier
frequency.
When the NTAG is positioned in the RF field, the high-speed RF communication
interface allows the transmission of the data and enables Bluetooth pairing.
