The PCF8578 is a low power CMOS1 LCD row and column driver, designed to drive dotmatrix graphic displays at multiplex rates of 1:8, 1:16, 1:24 or 1:32. The device has40 outputs, of which 24 are programmable and configurable for the following ratios ofrows/columns: 32¤8, 24¤16, 16¤24 or 8¤32. The PCF8578 can function as a stand-alone LCDcontroller and driver for use in small systems. For larger systems it can be used inconjunction with up to 32 PCF8579s for which it has been optimized. Together these twodevices form a general purpose LCD dot matrix driver chip set, capable of driving displaysof up to 40960 dots. The PCF8578 is compatible with most microcontrollers andcommunicates via a two-line bidirectional bus (I2C-bus). Communication overhead isminimized by a display RAM with auto-incremented addressing and display bankswitching.

PCF8562是一种能与几乎所有低复用速率的LCD接口的外围设备。它为所有静态和复合的LCD(包含最多4个背极和32段)产生驱动信号。PCF8562与大多数微处理器/微控制器兼容并可以通过两线双向的I2C总线通信。通过带自动增量寻址的显示RAM、硬件子地址寻址和显示存储器切换(静态和复合驱动模式)可以将通信的开销降至最低。
