PRELIMINARY PRODUCT INFORMATION
MOS INTEGRATED CIRCUIT
µPD161831
240/244-OUTPUT TFT-LCD SOURCE DRIVER WITH TIMING GENERATOR
(COMPATIBLE WITH 64-GRAY SCALES)
DESCRIPTION
The µPD161831 is a source driver for LIPS TFTs with on-chip timing generator and featuring 240/244 outputs. Data
input as 6-bit x 3-dot digital data is output as 64 γ -corrected values using an internal D/A converter, achieving
260,000-color (full-color) display.
FEATURES
• CMOS level input
• 240/244 outputs (R, G, B output)
• Input of 6 bits (gray-scale data) by 3 dots
• Capable of outputting 64 values by means of 5 external power modules and a D/A converter
• Output dynamic range: VSS + 0.05 V to VS – 0.05 V
• High-speed data transfer: fCLK = 20 MHz MAX. (during 2-times data transfer when operating at VCC = 2.5 V. During
1-time data transfer 10 MHz MAX.)
• High-speed data transfer: fCLK = 16 MHz MAX. (during 2-times data transfer when operating at VCC = 2.2 V. During
1-time data transfer 8 MHz MAX.)
• On-chip power supplies (driver power supply, gate top power supply, gate bottom power supply)
• Logic power supply voltage (VCC): 2.2 to 3.6 V
• DC/DC reference power supply (VDC): 2.5 to 3.6 V
• On-chip timing generator (Outputs R, G, B switching signal to panel. Outputs gate control signal.)
• On-chip 8-bit serial interface (applied to SPI)
