P89LPC9107FN

8位微控制器有两个时钟加速的80C51的核心具有1KB 3伏字节可擦除闪存的8位A / D转换器 8-bit microcontrollers with two-clock accelerated 80C51 core 1 kB 3 V byte-erasable flash with 8-bit A/D converter

The is a 8-bit Microcontroller based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. The device features 1kB byte-erasable flash code memory organized into 256-byte sectors and 16-byte pages and single-byte erasing allows any bytes to be used as non-volatile data storage, 128-byte RAM data memory, Two 16-bit timer/counters, 23-bit system timer that can also be used as a RTC, four input multiplexed 8-bit A/D converter/single DAC output and one analog comparator with selectable reference.
