| Abstract: | This paper proposed a solution which is the design of embedded multi-function handheld terminals based on PXA320 processor, according to single data collection methods and transfer data pathway at present. The device is based on the PXA320 processor core board. This paper not only designs audio codec module, camera module and LCD module, but also designs RFID module, bluetooth and WiFi module circuit. For handheld devices power, the device with intelligent power management chip LP3972 are adopted to system power supply circuit design. Hardware testing, the hand-held terminal can be stable and re- liable operation. |
