Overview of the EX USB Controllers
CHAPTER 2
Integrating the 3M™ MicroTouch™ EX USB
Controllers
The 3M™ MicroTouch™ EX USB controller provides a drop-in replacement for an
existing controller with wide dynamic range, increased noise immunity, wide operating
temperature stability, reprogrammability using software utilities and improved capability
in ungrounded environments.
The firmware for the EX121 and EX111 series USB controllers is optimized for surface
capacitive sensors integrated in the latest flat panel displays.
This chapter covers the following EX controller specifications:

The EX II ASIC has a built-in Universal Serial Bus (USB) full speed interface. A full
speed USB interface has a data rate of 12 Mb/s. The USB core in the ASIC was designed
to USB specification revision 1.1 but is forward compatible with revision 2.0.
A 25-point linearization procedure has been performed to determine the physical
properties of the sensor, and the data is stored in a 2D bar code label attached to the flex
tail.
To integrate and test the EX USB controller, you need the following items:
•
Cable connections
Mounting requirements
Power requirements and options
Status LED codes
The EX121 is available either cased or uncased for external or internal mounting.
The EX111 is available uncased without cable for mounting within a custom chassis.
A 3M™ MicroTouch™ surface capacitive sensor (available in a variety of sizes).
