Overview
The LC19001A010 provides rapid and precise position detection for the resistive membrane pressure-sensitive digitizers used in PDAs and other portable information processing equipment. It implements, in a single chip, the coordinate readout processing required for pen input operations.

FEATUREs
• Detects input coordinate values from resistive membrane pressure-sensitive digitizers at readout speeds up to 190 points per second using a 10-bit A/D converter.
• Compact size, low power, and the 3.3 V power supply operation appropriate for PDAs and other portable information-processing equipment
• Menu area registration, duplicate coordinate processing, and 4-byte packets reduce the host CPU processing load.
• Logical exclusion of abnormal coordinates and averaging processing to remove both pen chattering noise and noise from the LCD system
• Controller functions can be programmed by sending command data from the host CPU.
