LC19001A010
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.

[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...
