In Internet of Things terminals,smart wear,HID and smart home,Bluetooth MCU needs to give consideration to wireless connection,local control and peripheral expansion.Qinheng CH58x series is based on highland barley RISC-V kernel,which integrates BLE RF,USB,NFC,touch detection and analog peripherals,providing a complete combination for low-power Bluetooth MCU selection.
First,storage configuration of qinheng CH582 bluetooth MCU
CH583 is a 32-bit RISC-V MCU/SoC integrated with BLE wireless communication.It adopts highland barley V4A,supports RV32IMAC and hardware multiplication and division.The chip is equipped with 32KB SRAM and 512KB Flash,which supports wireless upgrade of ICP,ISP,IAP and OTA.The minimum working voltage is 1.7V,with built-in AES-128 and chip unique ID,which can be used for firmware protection and equipment identification.
Second,the RF and protocol of Qinheng CH582 Bluetooth MCU
This series has built-in 2.4GHz RF transceiver,baseband and link control,and is compatible with BLE 5.3.The air interface rate supports 2Mbps,1Mbps,500Kbps and 125Kbps,the receiving sensitivity is-98dBm,and the transmission power can be programmed to+6dBm.Providing protocol stack and application layer API can reduce the bottom adaptation of Bluetooth MCU.Built-in temperature sensor and RTC,RTC supports timing and trigger mode,which is convenient for low power scheduling.
Third,Qin Heng CH582 Bluetooth MCU peripheral resources and packaging
CH583 integrates 2 sets of USB2.0 full-speed Host/Device,4 sets of UART,2 sets of SPI,1-channel IIC and 12-channel PWM；;There are also 14 channels of 12-bit ADC and 14 channels of touch buttons.Four out of 40 GPIO support 5V input,which simplifies level matching.Packaged as QFN48 and QFN28,it is suitable for Bluetooth MCU applications with limited space.
