FEATURES  
DESCRIPTION  
The LM8300/8500 is a 4-wire resistive touch screen  
controller. The controller samples and drives the  
touch screen without the need of any external

Maximum Speed of 500 Coordinate Pairs per  
Second  
maximum of 500 coordinate pairs per second (cpps).  
The data sampled from the touch screen is sent out  
on the UART at a speed of 38400 bps.

Automatic Wake Up and Return to Standby  
10 bit A/D  
The controller has a power-saving mode which  
causes the controller to self-power down when no  
touch is detected on the touch screen for a specified  
amount of time. In the self-power down mode, the  
current drawn is typically less than 2 µA. The device  
resumes normal operation when a touch is detected  
on the touch screen or communication is detected on  
the UART. In addition to the self-power down mode,  
the controller can be disabled by pulling the  
SHUTDOWN pin low. The controller resumes normal  
operation when the SHUTDOWN pin is tristated or  
pulled high.
