Description
The STE2002 is a low power CMOS LCD controller driver. Designed to drive a 81 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 externals components and in a very low power consumption. The STE2002 features three standard interfaces (Serial, Parallel & I2C) for ease of interfacing with the host microcontroller.
