LC19001A010

Ordering number : EN*5560B CMOS LSI LC19001A010 Digitizer Controller Preliminary Overview The LC19001A010 provides rapid and precise position detection for the resistive membrane pressure-sensitive digitizers used in PDAs and other portable informationprocessing equipment. It implements, in a single chip, the coordinate readout processing required for pen input operations. This controller provides the following functions: digitizer voltage A/D conversion, noise exclusion, conversion to display coordinates, and data transfer to the host CPU. Package Dimensions unit: mm 3326-LQFP80 [LC19001A010] 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.
