2 OVERVIEW
LPZigBee module mainly consists of two sections: The System-on-Chip (EM357) and
the RF front-end (SE2432L) with power amplifier and low-pass filtering.
The EM357 includes radio transceiver and microcontroller. The radio transceiver
handles all actions concerning RF modulation/demodulation, signal processing, frame
reception and transmission. MAC hardware acceleration functions are implemented
in the radio transceiver, too. Further information about the radio transceiver and the
microcontroller are available in the appropriate datasheets, refer to 1.5 references.
The RF front-end incorporates signal amplification and filtering of the transmit signal.
The degree of filtering depends on operating conditions as well as regional aspects.
Switching between reception and transmission is directly controlled by the radio
transceiver.

5 BLOCK DIAGRAM AND PORT FUNCTION
5.1 UART
P
ORT
LPZigBee Module provides four signals (RX, TX) of standard RS-232 protocol to
support user applications. The UART port is set the DCE port and connected with
other devices by D-Sub-9 Female connector. But the RX, TX connection between
RS-232 Transceiver and D-Sub-9 Female connector can be reversed by Jumpers,
allowing use of connecting straight-though or cross-wires cable.

ORT
The LPZigBee module can be programmed and debugged by JTAG port. It is a 20
pins header and connects with Atmel’s debugging tool.
5.3 GPIO

Federal Communication Commission Interference Statement
This module 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 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.
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.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the
antenna and users, and
2) The transmitter module may not be co-located with any other transmitter or
antenna
As long as 2 conditions above are met, further transmitter test will not be required.
However, the OEM integrator is still responsible for testing their end-product for any
additional compliance requirements required with this module installed (for example,
digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions can not be met (for example
certain laptop configurations or co-location with another transmitter), then the FCC
authorization is no longer considered valid and the FCC ID can not be used on the
final product. In these circumstances, the OEM integrator will be responsible for re-
evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may
be installed such that 20 cm may be maintained between the antenna and users. The
final end product must be labeled in a visible area with the following: “Contains FCC
ID: ZAR-TGPBA0010260”.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the end
product which integrates this module.
The end user manual shall include all required regulatory information/warning as
show in this manual.
