目前TWS 蓝牙无线耳机已经较为大众接受,TWS蓝牙耳机充电盒虽然是耳机附件，但是它的作用至关重要，由于耳机盒设计比较精致，体积较小，导致电池容量不高，需要长途物流、静默搁置，所以超低自放电是一项硬性指标.但目前TWS蓝牙充电耳机盒大都还是使用MiCRO USB 连接线来对蓝牙无线耳机充电盒充电,使用者外出必须携带 Power Bank +MiCRO USB, Type C (Android) + Lightning (iPhone) Apple等等线材,若是Power Bank 也是无线充电是否可以改善如此多线的麻烦事. 所以基于方便性及相容性将Semtech 无线充电RX 5W(Qi)方案导入无线耳机充电盒来应用,也可以将无线充电耳机盒设计成防水防尘等级的无线充电盒.使用Semtech RX 5W(Qi)无线充电并可以相容于TX(Qi)无线充电板.

The μPSD32xx family, from ST, consists of Flash programmable system devices with a 8032 MicrocontrollerCore. Of these, the μPSD3234A and μPSD3254A are notable for having a complete implementationof the USB hardware directly on the chip, complying with the Universal Serial Bus Specification, Revision1.1.This application note describes a demonstration program that has been written for the DK3200 hardwaredemonstration kit (incorporating a μPSD3234A device). It gives the user an idea of how simple it is to workwith the device, using the HID class as a ready-made device driver for the USB connection.IN-APPLICATION-PROGRAMMING (IAP) AND IN-SYSTEM-PROGRAMMING (ISP)Since the μPSD contains two independent Flash memory arrays, the Micro Controller Unit (MCU) can executecode from one memory while erasing and programming the other. Product firmware updates in thefield can be reliably performed over any communication channel (such as CAN, Ethernet, UART, J1850)using this unique architecture. For In-Application-Programming (IAP), all code is updated through theMCU. The main advantage for the user is that the firmware can be updated remotely. The target applicationruns and takes care on its own program code and data memory.IAP is not the only method to program the firmware in μPSD devices. They can also be programmed usingIn-System-Programming (ISP). A IEEE1149.1-compliant JTAG interface is included on the μPSD. Withthis, the entire device can be rapidly programmed while soldered to the circuit board (Main Flash memory,Secondary Boot Flash memory, the PLD, and all configuration areas). This requires no MCU participation.The MCU is completely bypassed. So, the μPSD can be programmed or reprogrammed any time, anywhere, even when completely uncommitted.Both methods take place with the device in its normal hardware environment, soldered to a printed circuitboard. The IAP method cannot be used without previous use of ISP, because IAP utilizes a small amountof resident code to receive the service commands, and to perform the desired operations.
