From Bluetooth specification 4.0 Start , The standard introduces low power Bluetooth . such Low power Bluetooth chip The working state is dormant most of the time , When something wakes up , The device is connected . So in the whole work cycle , comparison 4.0 The previous standard ,ULP It will save more power .
 
Bluetooth radio is all Bluetooth 4.0 The functions that must be supported by the above devices . It doesn't involve the higher layers of connectivity and protocol . A message that is transmitted by Bluetooth broadcast packets , Better real-time and compatibility on Bluetooth devices . At the same time, the word length of Bluetooth broadcast is at most 31 Bytes , Especially suitable for the transmission of some small amount of data . Sensors like thermometers . The important function of Bluetooth broadcast channel is to discover devices , Initiate connections and release data .
 
Shanghai Juwei The chip based on Bluetooth broadcast channel MG127 It integrates all the necessary functions and parameter settings of Bluetooth broadcast transceiver . You can set the transmission content and interval and power .
 
◆ Support 3 Line SPI Communications
 
◆ compatible BLE-Beacon standard
 
◆ Can be configured to receive and transmit , Single duplex broadcasting
 
◆ Small volume 3mmX3mm, encapsulation DFN10, The cost is low :
 
◆ Support remote control mode :
 
• The remote control has a special chip for giant and micro ( Support 4 A button )
 
• More buttons need to be simple MCU
 
• A giant micro RF chip at the receiving end MG127+ A simple one MCU
 
• At the same time, it can be controlled by remote control and mobile phone
 
◆ compatible BluetoothSmart Broadcasting standards and 2.4G Private agreements
 
◆ Embedded Beacon Launch procedure , It can be sent regularly Beacon data :
 
• Content 、 The length is configurable
 
• The device name can be configured
 
• Bluetooth address can be configured
 
•UUID Configurable
 
•Beacon The broadcast interval can be configured
 
• The transmission power can be configured (-18~4dBm)
 
◆ Less than 3 Peripheral devices
 
◆ Standby current <3uA
 
◆ Emission current <20mA@0dBm
 
Giant micro Bluetooth chip MG127 It is a low-power and low-cost BLE Transceiver , Internally integrated transmitter and receiver 、GFSK Modem and BLE Baseband processing . The package uses DFN3x3,MG127 The power supply voltage of the chip is 1.9V~3.6V, You can use a button battery (3.0v) Power supply ,3uA Standby current ,20mA@0dBm Keep firing ,18mA Keep receiving . peripheral BOM Very few , Just low cost MCU coordination . Since the chip came out , Received the general industry welcome . The chip has stable quality and excellent compatibility . Yingshang microelectronics, a Shanghai giant micro agent, provides development board and DEMO Board and software support .
