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.

This controller provides the following functions: digitizer

voltage A/D conversion, noise exclusion, conversion to

display coordinates, and data transfer to the host CPU.

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.
