STE2102 240x320RGB single-chip true 262K colors ramless LCD controller/driver Data Brief Features Description ■ 240 x 320RGB display matrix ■ 8 colors & 262K colors modes ■ Programmable number of lines ■ Programmable frame & N-line polarity inversion ■ System interfaces (read and write) – I2C – 3-lines SPI – 3-lines 9 bits Serial Interface – 4-lines SPI The STE2102 is a low power CMOS single-chip TFT controller/driver featuring an extremely low current consumption thanks to an innovative charge pump architecture. Designed to drive a 240 rows by 320RGB columns 262k colors graphic display, with amplitude modulation method, the STE2102 provides all the necessary functions in a single chip, including on-chip gate drivers supply, source drivers supply and source reference voltages generators, resulting in a minimum of externals components. ■ Graphics interfaces: – 16/18Bit RGB Interface – 8Bit YCrCb 4:2:2 Interface STE2102 features an high-speed RGB interface to transfer flicker-free video data, an 8-bit YCrCb digital video interface and several bi-directional serial interfaces to configure the display. ■ Programmable Gamma look-up tables for optimum colour configuration. The IC is designed to operate with both traditional Cap-on-CE and with Cap-On-Gate panels. ■ Fully integrated Bias system and voltage generator ■ Designed for chip-on-glass (COG) and chip-on-foil (COF) applications ■ Logic supply voltage range from 1.5 to 1.95V ■ Interface and control signals supply voltage range from 1.5 to 3.6V ■ High voltage generator supply voltage range from 2.2 to 3.6V ■ Selectable scan direction ■ Common electrode and gate-off switching ■ Cap-on-common and cap-on-gate (patented) TFT structures ■ Gate, common and source waveform timing generation digitally tunable ■ Gate drivers voltage range from -15 to 16.5V ■ Source drivers voltage range from 0 to 5.5V ■ Common driver voltage range from -2.5 to 4.5V ■ On chip calibration (with OTP Cells) of Key configuration parameters December 2006 Rev 1 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com 4 STE2102 Table 1.
