SZU06C1 introduced in this document is an embedded wireless communication module based
on IEEE802.15.4/ZigBee technology. The hardware has taken the EFR32MG1B232 chip
solution of Silicon Labs and the software supports ZigBee alliance ZSE standard protocol
family and also is complaint with ZigBee Metering Implementation - Great Britain Companion
Specification.
And now the module has passed EU’s ATEX, CE, RoHS and US’s FCC approval.
You can add the strong network function into your products without radio frequency experience
or expertise, which can greatly shorten the research and development period of products and
further speed up the marketing of the products.
1.2 Hardware description

low power consumption RF chip EFR32MG1B232 from Silicon Labs, 38.4MHz system clock
crystal oscillator, 32.768KHz monitoring clock oscillator and RF radio frequency front-end
matching circuit which can optimize the radio frequency performance.
The module provides U.FL interface for attaching external SMA interface antenna or PCB
antenna.
The maximum output power of RF chip is 19.5dBm, and the receive sensitivity is -101dBm
typically.

When SZU06C1 ZigBee wireless communication module is embedded into an OEM product, it
is prohibited to declare that his OEM products comply with CE certification in the name of
approved CE certification of our company. If the OEM manufacturer wants to declare that his
final products comply with CE certification, it must be ensured that the final products shall
comply with the European EMC, Radio and Safety standards. Otherwise, ChengDu DiYue
Technology Co., Ltd. has the right to investigate and affix the responsibility for it.

The "CE" marking must be placed in a prominent position of OEM products. Please refer to
http://ec.europa.eu/enterprise/faq/ce-mark.htm for more information about CE certification
mark.
Important tips:
In Europe, frequency band of 2.4GHz is used only for the equipment with the maximum
equivalent isotropically radiated power (e.i.r.p.) of less than 10mW(10dBm). In case that e.i.r.p.
of the equipment is more than 10mW, the Manufacturer or Authorized Agent must notify the
competent authorities of the spectrum management of the relevant member state prior to four
weeks that the products are put on the market. Besides, the equipment must be marked with
warning symbol to draw the user's attention to the fact that it might not be legal to use the
equipment in every member state.
For this reason, we recommend that the European customers limit the output power to 10mW
(10dBm) to avoid having to deal with the local authorities for spectrum management of each
relevant member state.
2.2 FCC Approvals
The SUZ06C1 ZigBee wireless communication module including the antenna listed is Table
2-1 have been tested to comply with Part 15 of the FCC rules. And the tested power level is:

4Hardware Description
4.1 Hardware Diagram
Fig. 4-1 Hardware Diagram of SZU06C1
SZU06C1 wireless communication module is based on EFR32MG1B2321 chip from Silicon
Labs, which integrates the RF transceiver complying with 2.4-GHz IEEE 802.15.4, high
performance 32-bit ARM 40MHz Cortex®-M4 CPU, 256KB FLASH and 32KB RAM which can
be programmed in the system and many other peripherals with strong functions. In addition,
the EFR32MG1B232 has multiple sleep modes, which makes it to be more adaptable to the
ultra-low power consumption system.It only takes a few milliseconds for change between
different power modes that further ensures the low power consumption of the equipment.
SZU06C1 wireless communication module provides 8-lines GPIO, one UART communication
interface, two debug interface（one is 2-wire SWD and the other is 4-wire JTAG). And you can
develop your custom software easily with them.
In addition to this a number of MAC functions are also implemented in hardware to help
maintain the strict timing requirements imposed by the ZigBee and IEEE802.15.4 standards.

5Firmware Description
5.1 Firmware introduction
SZU06C1 ZigBee wireless communication module with firmware supports ZigBee alliance
ZSE standard protocol family and also is complaint with ZigBee Metering Implementation -
Great Britain Companion Specification.
SZU06C1 ZigBee wireless communication module integrated boot loader program supports
firmware updating by UART interface.
Each module has only 64-bit identifier stored in FLASH, which is similar to the MAC address in
PC. And now, our module can only act as an end device, which is not equipped with wiring
function, so it can be going to sleep mode (so the end device generally applies battery for
power supply), and also can send and receive data through the router of parent node. An end
device is also equipped with the function to constantly change its location and parent node in
the network.
5.2 Customized firmware
For customers who have batch requirements of SZU06C1 module, we can customize the
firmware on their demand.

Notes:
Reference sensitivity level is -85 dBm.
Filter is characterized as a symmetric band-pass centered on the adjacent channel having a
3dB bandwidth of 4.6 MHz and stop-band rejection better than 26 dB beyond 3.15 MHz from
the adjacent carrier.
