General Description
The LLCC68 sub-GHz radio transceiver Module is ideal
for long range wireless applications. It is designed for long battery
life with just 4.2 mA of active receive current consumption.
The LLCC68 module can transmit up to +22 dBm with
highly efficient integrated power amplifiers.
The LLCC68 Module supports LoRa® modulation for
LPWAN use cases and (G)FSK modulation for legacy use cases. It
is highly configurable to meet different application
requirements for industry and consumer use.
The device provides LoRa® modulation compatible with
Semtech transceivers used by the LoRaWAN™
specification released by the LoRa Alliance™.
The radio is suitable for systems targeting
compliance with radio regulations including but not limited to ETSI
EN 300 220, FCC CFR 47 Part 15, China regulatory
requirements and the Japanese ARIB T-108. Continuous frequency
coverage from 150 MHz to 960 MHz allows the support
of all major sub-GHz ISM bands around the world.

Electric Specification

Module Size and Pin Definition
ApplicationNotice
1、 Voltage cannot be out of the
range of the module’s power supply voltage 1.8 ~ 3.6V, if it is over 3.6V the
chip will burn out. Recommending voltage is 3.3V.
2、Module interfaceadopt
semicirclebonding pad, all GNDpin shouldkeep reliableconnectionwithdigital
ground ofcircuit.
3、Antenna should keep away from systemground.
4、MCU does not have SPI port single-chip and can imitate SPI time to
carry out theread-writeoperation by using ordinary I/O port. SPI
rate do not over10MHz.
5、If the power supply of MCU is 3.3V,it can connect with module without series resistance; ifthe powersupply of MCU is 5V, 3.3V/5V
level switching circuit should beaccessed

7.1Remark
1.The communication rate of
module will effect communication distance, the higher the communication rate
is, the shorter the communication distance willbe.
2.The communication rate of
module will effect RX sensitivity, the
higher the communication rate is,the
lower the RX sensitivity willbe.
3.The power supply voltage will effect transmit power, within
the allowable range of working power supply voltage, the lower the voltage is,
the lower the transmit power willbe.
4.The change of working temperature may cause the migration of
the working frequency. It has no
influence to the application as long as the temperature is within the working
temperaturerange.
5.Antenna affect much to the communication distance, so should
apply the antenna which matches module’s
frequency, standing-wave ratio should be small and impedance is close to50ohm
