Pin Assignment
The MK712 Touch Screen Controller IC provides
all the screen drive, A to D converter and control
circuits to easily interface to 4-wire analog resistive
touch screens.
The IC continually monitors the screen waiting
for a touch. In this mode, the supply current is
typically 0.5μA. When the screen is touched, the
IC performs analog to digital conversions to
determine the location of the touch, stores the X
and Y locations in the registers, and issues an
interrupt. This process is repeated up to 197 times
per second until no further screen touches are
detected, at which time the low current mode is
resumed.

Fully integrated, lowest power solution
Low standby current of 0.5μA (typical) at 5.0V
Active current while converting less than 10 mA
Resolves 350 dots/inch on 10.5” display
Maximum speed of 197 points/second
Ratiometric conversion may eliminate screen
calibration
Automatically wakes up and goes back to standby
3.3V or 5V supply
12 bit A/D converter
Simplifies the writing of software for touch screens
