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 information-
processing equipment. It implements, in a single chip, the
coordinate readout processing required for pen input
operations.

[LC19001A010]
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.
