1. DESCRIPTION
The ST8009 is a 96-output segment/common driver IC
suitable for driving small/medium scale dot matrix LCD
panels, and is used in PDA or electronic dictionary.
The ST8009 is good as a segment driver, a common
driver or a common/segment driver, and it can create
low power consumption, high-resolution LCD. The
ST8009 have eight modes can selected to set
common and segment numbers by selecting register.
The ST8009 also have analog DC/DC converter to
use.
