When choosing Bluetooth MCU,it is often necessary to find a balance between power consumption,peripherals and cost.Qin Heng CH573 is a RISC-V MCU/SoC integrated with BLE communication,which packs RF,USB and common peripherals into one chip and is suitable for battery-powered and volume-sensitive Bluetooth products.
1.QinHeng CH573 Bluetooth MCU:Kernel and Storage
CH573 adopts RISC-V kernel,clocked at 20MHz,and comes with 448K ROM and 18K RAM,which is enough to put down the protocol stack and application logic without expanding Flash,and the BOM and board area can be reduced.
2.QinHeng CH573 Bluetooth MCU:low power consumption and power supply
The power supply range of Qinheng CH573 Bluetooth single chip microcomputer is 1.7V~3.6V,and a single lithium battery can directly supply power.DCDC current is about 6 ma when 0dBm is transmitted;Deep sleep is 1.4uA~6uA,and power consumption during shutdown is 0.3uA.For button cell or small-capacity battery equipment,these numbers directly determine the battery replacement cycle.
3.QinHeng CH573 Bluetooth MCU:BLE RF performance
CH573 conforms to BLE 4.2 specification,with transmitting power of+5dBm and receiving sensitivity of-96dBm.The link margin of typical scenes such as indoor and desktop is enough;The power is adjustable,and the power consumption and communication distance can be chosen according to the product positioning.
4.QinHeng CH573 Bluetooth MCU:on-chip peripherals
Bluetooth MCU has complete on-chip resources:1 full-speed USB host/device controller,4 UART,1 SPI,12-bit 10-channel ADC,10-channel touch detection,and 4 groups of 26-bit timers,4+8 PWM and RTC.Do keyboard,handle,touch and PWM directly;Connect sensors or power collection,and the number of ADC channels is enough.
5.QinHeng CH573 Bluetooth Single Chip Microcomputer:Packaging and Application
Qinheng CH573 Bluetooth MCU is available in QFN32(4×4)and QFN28(4×4)packages,and its working temperature is-40 C~85 C..Common landing scenes include keyboard and mouse,game pad,electricity/water/gas meter,anti-lost device,mobile phone peripherals,intelligent door locks,sensors and light-controlled remote control.When selecting the model,it is suggested to check the data sheet with the power consumption budget and the number of peripherals occupied before setting the board.As a first-class agent of QinHeng,we can provide a complete specification and design scheme.If you need it,please feel free to call us.
