STE2001 Datasheet - STMicroelectronics

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
