ZLG P89LPC932 Flash Microcontroller User Guide
This guide from Guangzhou Zhouligong MCU Development Co., Ltd. (ZLG) describes the P89LPC932, a single-chip microcontroller suited to applications that need high integration and low cost. According to the introduction, it uses a high-performance processor architecture with instruction execution times of only 2 to 4 clock cycles, six times that of standard 80C51 devices, and it integrates system-level functions that reduce component count, board area and system cost.
The document shows the 28-pin TSSOP and 28-pin PLCC pin configurations and the logic symbol, then describes the pins of ports P0 through P3 with their alternate functions, including keyboard interrupts, comparator inputs, UART, I2C, SPI, capture/compare channels and the clock output. A large reference section lists the special function registers with their names, addresses, bit functions and reset values. This manual is written in Chinese.
