LC19001A010 Datasheet | SANYO

Ordering number : EN- 5560B CMOS LSI 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. - pact 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 mand data from the host CPU.
