LM8300/LM8500
Four Wire Resistive Touchscreen Controller with
Brownout
1.0 General Description
The LM8300/8500 is a 4-wire resistive touch screen control-
ler. The controller samples and drives the touch screen
without the need of any external hardware. The built in 10-bit
A/D provides a 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.
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 SHUT-
DOWN pin low. The controller resumes normal operation
when the SHUTDOWN pin is tristated or pulled high.
The controller has an internal non-volatile memory storage
element to store configuration data such as calibration points
or controller configurations.
