ZLG P89LPC901 Microcontroller Data Sheet
This document is the Chinese-language data sheet for the P89LPC901 single-chip microcontroller, distributed by Guangzhou Zhouligong (ZLG). It describes a high-performance 80C51-type CPU core that executes instructions in 2 to 4 clock cycles, roughly six times faster than a standard 80C51 at the same clock rate.
The text covers features, pin configuration and pin descriptions for the 8-pin SO-8 package, special function register addresses and bit definitions, plus port, timer, watchdog, comparator, oscillator and reset details. This manual is written in Chinese.
