TOUCH SCREEN CONTROLLER

MK712

Description

Features

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.

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

mil)

• Industrial (-30°C to +70°C) and commercial (0 to +70°C)

and automotive (-35°C to +85°C) temperature ranges

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.

• Pb (lead) free

• Fully integrated, lowest power solution

• Low standby current of 0.5µA (typical) at 5.0 V

• Active current while converting less than 10 mA

• Resolves 350 dots/inch on 10.5” display

• Maximum speed of 197 points/second

• Ratio metric conversion may eliminate screen calibration

• Automatically wakes up and goes back to standby

• 3.3 V or 5 V supply

Block Diagram

• 12 bit A/D converter

• Simplifies the writing of software for touch screens

• Extended temperature range available

• 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
