PCF8579规格书详情
GENERAL DESCRIPTION
The PCF8579 is a low power CMOS LCD column driver, designed to drive dot matrix graphic displays at multiplex rates of 1 : 8, 1 : 16, 1 : 24 or 1 : 32. The device has 40 outputs and can drive 32 × 40 dots in a 32 row multiplexed LCD. Up to 16 PCF8579s can be cascaded and up to 32 devices may be used on the same I2C-bus (using the two slave addresses). The device is optimized for use with the PCF8578 LCD row/column driver.
