GENERAL DESCRIPTION
The PCF8578 is a low power CMOS LCD row/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, of which 24 are programmable,
configurable as
32
8
,

16
,

24
or

32
rows/columns.
The PCF8578 can function as a stand-alone LCD
controller/driver for use in small systems, or for larger
systems can be used in conjunction with up to
32 PCF8579s for which it has been optimized. Together
these two devices form a general purpose LCD dot matrix
driver chip set, capable of driving displays of up to
40960 dots. The PCF8578 is compatible with most
microcontrollers and communicates via a two-line
bidirectional bus (I
2
C-bus). Communication overheads are
minimized by a display RAM with auto-incremented
addressing and display bank switching.
