Description of the Invention (1) The present invention relates to the technology of handheld electronic devices, and in particular, to a handheld device that synchronizes with a personal computer. In a modern society where information is rapidly changing, personal computers are almost an essential tool for modern people. In addition, PDA (Personal Digital Assistant) combined with computer, communication, and consumer electronics technology has the advantages of light weight, easy to carry, and the ability to store personal data (such as business cards, memo records, and schedules). Widely favored by consumers. At present, many manufacturers have been required to design and produce various PDAs in response to market demand. Looking at these commercialized PDAs, it is not difficult to find that PDAs are continuously developing towards miniaturization, low price, and the ability to communicate with personal computers (PC: Personal Computer). Among them, more typical representative products such as PILOT from 3COM, NEWTON from APPLE, etc. However, the conventional PDA uses two methods to implement data transmission with a personal computer: one is a serial transmission mode; the other is a personal computer memory card international association (hereinafter PCMCIA calls it) one of the standard memory cards for data storage and synchronization. Although the former is more cost-effective through serial communication, but the transmission speed is slower. Generally, the transmission of data requires the installation of an additional cradle and RS-232 connection, which is quite difficult to use. As for the PCMCIA memory card, although it is fast and requires no external wiring, it is necessary to set up an independent processor and memory at each conventional PDA (read-only memory, flash memory, random access memory, etc.) , Making the overall structure redundant and redundant, it will also increase the number of students __ 3 This paper is suitable for us (CNS) A4 ^ (2 丨 Gx297).
