Motorola MVME 147-P3是一種嵌入式微處理器，是Motorola公司在1980年代后期推出的一款基于8051微處理器的單板機(jī)。它具有8051微處理器的所有功能，同時(shí)具有可擴(kuò)展的內(nèi)存和I/O接口，適用于各種嵌入式控制應(yīng)用。
特點(diǎn)包括：
* 基于8051微處理器，具有8位數(shù)據(jù)總線，128字節(jié)的RAM和4K字節(jié)的ROM。
* 可通過擴(kuò)展槽進(jìn)行內(nèi)存和I/O接口的擴(kuò)展。
* 支持多種外設(shè)接口，如串口、并口、AD轉(zhuǎn)換器等。
* 支持實(shí)時(shí)操作系統(tǒng)（RTOS）和開發(fā)工具，方便應(yīng)用程序的開發(fā)和維護(hù)。
* 適用于各種嵌入式控制應(yīng)用，如工業(yè)自動(dòng)化、智能儀表、醫(yī)療設(shè)備等。

總之，Motorola MVME 147-P3是一款功能強(qiáng)大的嵌入式微處理器，在當(dāng)時(shí)的嵌入式應(yīng)用領(lǐng)域具有廣泛的應(yīng)用和影響力。

It is an bded microprocessor, a single board computer based on the 8051 microprocessor launched by Motorola in the late 1980s. It has all the functions of an 8051 microprocessor, as well as expandable memory and I/O interfaces, suitable for various bded control applications.
Features include:
*Based on an 8051 microprocessor, with an 8-bit data bus, 128 bytes of RAM, and 4K bytes of ROM.
*Memory and I/O interface expansion can be achieved through expansion slots.
*Support multiple peripheral interfaces, such as serial port, parallel port, AD converter, etc.
*Supports real-time operating systems (RTOS) and development tools, facilitating the development and maintenance of applications.
*Suitable for various bded control applications, such as industrial automation, inbligent instruments, medical equipment, etc.
In summary, Motorola MVME 147-P3 is a powerful bded microprocessor with extensive applications and influence in the field of bded applications at that time.
