The P87LPC759 is a high-performance low-power 8-bit microcontroller that uses a 20MHz high-speed clock. Its instruction execution time is only 300-600ns, which accelerates the execution efficiency of 80C51 instructions and has a 1K-byte OTP program storage and 64 bytes of RAM to meet user needs. Various application requirements.
This manual describes the features and electrical characteristics of the ZLG P87LPC759 microcontroller, including operating frequency, voltage ranges, memory size, and I/O capabilities. It also covers programming options such as OTP memory and EPROM safety features.
The document includes pin‑out tables, package information (14‑lead DTP and JPDIP), interrupt sources, timer functions, and LED drive specifications, helping designers integrate the device into their circuits. This manual is written in Chinese.
