DESCRIPTION
The STE2001 is a low power CMOS LCD controller
driver. Designed to drive a 65 rows by 128 columns
graphic display, provides all necessary functions in a
single chip, including on-chip LCD supply and bias
voltages generators, resulting in a minimum of exter-
nals components and in a very low power consump-
tion. The STE2001 features three standard interfaces
(Serial, parallel, I2C) for ease of interfacing with the
host µcontroller.
