MK712R General Description

TOUCH SCREEN CONTROL
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 0.5A. 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.

Packaged in 28-pin SSOP (150 mil) or 28-pin SOIC (300 mil)

Industrial (-30°C to +70°C), commercial (0 to +70°C), and automotive (-35°C to +85°C) temperature ranges

Available in Pb (lead) free package

Fully integrated, lowest power solution

Low standby current of 0.5A (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

Extended temperature range available o Capacitors are the only external components required

Touch screen is directly driven - no external transistors are required

Programmable conversion rate

A to D Converter is monotonic

Parallel interface
