1. introduction
st7567 is a single-chip dot matrix lcd driver which incorporates lcd controller and common/segment drivers. st7567
can be connected directly to amicroprocessor with 8-bit parallel interface or 4-line serial interface (spi-4). display data sent
from mpu is stored in the internal display data ram (ddram) of 65x132 bits. the displaydata bits which are stored in
ddram are directly related to the pixels of lcd panel. st7567 contains 132 segment-outputs, 64 common-outputs and 1
icon-common-output. withbuilt-in oscillation circuit and low power consumption power circuit, st7567 generates lcd
driving signal without external clock or power, so that it is possible to make a display systemwith the fewest components
and minimal power consumption.
