With the rapid development of Internet of Things devices,smart homes and wearable products,BLE Bluetooth chip and highly integrated Bluetooth chip MCU have become the core components in various wireless solutions.So how to choose a BLE Bluetooth chip with high performance and low power consumption?A BLE Bluetooth chip with high performance and low power consumption should have the following characteristics:
①High performance kernel and storage configuration of BLE Bluetooth chip.
②Compatibility between high-performance RF and Bluetooth
③High speed USB and rich interfaces.
④Diversified expandability of④BLE Bluetooth chip.
⑤Low voltage and multi-package options
CH585,introduced by Nanjing Qinheng Microelectronics,is a RISC-V core MCU that integrates BLE 5.4 wireless communication,high-speed USB and NFC functions.It has both high performance and low power consumption,and is very suitable for complex wireless application scenarios.CH585 is a wireless system on a chip(SoC)based on RISC-V architecture,which integrates 2Mbps BLE Bluetooth communication,high-speed USB 2.0(480Mbps)controller,NFC interface and abundant peripheral resources in a single chip.BLE Bluetooth chip not only supports the latest BLE 5.4 standard,but also is compatible with high-speed 2.4G private protocol,which can achieve the highest report rate of 8kHz and meet the high-response demand scenarios such as mouse,remote controller and wearable device.
BLE Bluetooth chip adopts highland barley 32-bit RISC-V core,supports RV32IMBC instruction set,has built-in 128KB SRAM and 512KB Flash,supports ICP,ISP,IAP and other burning methods,and has OTA wireless upgrade capability,which is convenient for later maintenance and function update of equipment.The BLE Bluetooth chip has a built-in 2.4GHz RF transceiver,with a receiving sensitivity of-95dBm and a maximum transmitting power of+4.5dBm.It supports the 2Mbps and 1Mbps transmission modes of BLE 5.4,and can flexibly switch to the 2.4 private protocol to realize low-delay and high-throughput communication.
The BLE Bluetooth chip CH585 has also been greatly optimized at the software level.Its virtual serial port technology allows developers to quickly integrate Bluetooth functions through simple serial port commands,and some models can even realize"instant use"without secondary development.At the same time,the chip supports Bluetooth,serial port and USB data intercommunication,which can be widely used in HID equipment,data acquisition,remote control and smart home central control.
In a word,CH585,as a high integrated BLE Bluetooth chip and Bluetooth chip MCU,has achieved a good balance in performance,power consumption and expansibility.Its perfect protocol stack,rich peripheral support and flexible interconnection ability can help developers lower the development threshold and shorten the product launch cycle,and it is an ideal choice for the design of a new generation of wireless devices.
