A/D converted data is sent to the host CPU.

Normalized data is sent to the host CPU.

Asynchronous serial communications External switches are used to set the initial communication rate.

See the “External Switch Settings” charts.

However, the LC19001A010 does not support 19200-bps communication at 8

Ordering number : 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: digitizer voltage A/D conversion, noise exclusion, conversion to dis

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.

* Compact size, low power, and the 3.3 V power supply operation appropriate for PDAs and other portable information-proc
