ZLG P87LPC760 Microcontroller User Manual
The P87LPC760 features an accelerated 80C51 core that runs up to 20 MHz with a supply voltage of 4.5‑6.0 V (2.7‑6.0 V minimum). It provides 1 KB OTP program memory, 128 B RAM, 32 B user code area, two 16‑bit timers, one on‑chip comparator, UART and I2C communication, and up to 12 configurable I/O pins.
The device is offered in 14‑pin DIP and TSSOP packages. It includes a watchdog timer with eight timeout selections, power‑on reset, low‑voltage reset, and oscillator‑failure detection. Detailed register maps, pin assignments, and peripheral configurations are described throughout the manual. This manual is written in Chinese.
