The document describes a low power CMOS LCD controller driver called STE2001. It is designed to drive a 65 rows by 128 columns graphic display and provides all necessary functions in a single chip, including on-chip LCD supply and bias voltage generators, resulting in a minimum of external components and low power consumption.
The STE2001 is a low-power CMOS LCD controller/driver designed to drive a 65-row by 128-column graphic display. It integrates the LCD supply and bias voltage generators, an oscillator, display data RAM, and scroll logic, and is intended for chip-on-glass (COG) applications.
The device supports I2C (Fast and Hs-mode, read and write), parallel (write only), and serial (write only) interfaces. The document is a product preview and includes pin descriptions, maximum ratings, and electrical characteristics.
