LC19001A010 Description
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:.
LC19001A010 Key Features
- Detects input coordinate values from resistive membrane pressure-sensitive digitizers at readout speeds up to 190 points
- pact size, low power, and the 3.3 V power supply operation appropriate for PDAs and other portable information-processin
- 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 th
- Controller functions can be programmed by sending mand data from the host CPU
