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.

3326-LQFP80
[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.

Note: 1. The LC19001A010 must be used with AVCC and VCC at the same potential.
Also, applications must assure that AVCC does not exceed VCC at power on.
2. VI and VO1 must not exceed VCC + 0.3 V.

<Notes> This LSI can be permanently damaged by use at stresses in excess of the absolute maximum ratings.
It is desirable that the LC19001A010 be operated within the recommended operating conditions during normal operation. In particular, the LSI’s
reliability may be adversely affected if these conditions are exceeded.
