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 externals components and in a very low power consumption. The STE2001 features three standard interfaces (Serial, parallel, I2C) for ease of interfacing with the host µcontroller.

■ 65 x 128 bits Display Data RAM

■ Configurable matrix: 65 x 128 or 33 x 128

■ Programmable (65/33) MUX rate

■ Row by Row Scrolling

■ Automatic data RAM Blanking procedure

■ Selectable Input Interface:

• I2C Bus Fast and Hs-mode (read and write)

• Parallel Interface (write only)

• Serial Interface (write only)

■ Fully Integrated Oscillator requires no external components

■ Fully Integrated Configurable LCD bias voltages generator with:

• Selectable (5X, 4X, 3X, 2X) multiplication factor

• Effective sensing for High Precision Output

• Four selectable temperature compensation coefficients

■ Designed for chip-on-glass (COG) applications

■ Programmable bottom row pads mirroring and top row pads mirroring for compatible with both TCP and COG applications

■ Low Power Consumption, suitable for battery operated systems

■ Logic Supply Voltage range from 1.9 to 5V

■ High Voltage Generator Supply Voltage range from 2.4 to 4.5V

■ Display Supply Voltage range from 4.5 to 9V
