LC19001A010 Digitizer Controller

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 MHz. The rate can be changed by command. External switches a.

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 sendi.
