In the embedded storage scheme,SPI NOR FLASH is widely used because of its simple interface,stable reading and easy direct access
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,US
The serial SPI STT‑MRAM memory chip has a density of 32Mbit,is compatible with Single Dual Quad SPI working modes,and supports SPI Mode0 and Mode 3 The highest SDR is 108MHz,and the DDR can reach 54MHz At the same time,it supports XIP to perform reading
