TM040040 Overview
TM040040 Overview
The TM040040 is a unique circular trackpad that is perfect for specialized input applications
such as game controllers and advanced consumer electronics. The TM040040 trackpad can be
configured to use either I
2
C or SPI host interfaces. The TM040040 is designed to use an
optional haptic module, which provides tactile feedback that enhances the end-user’s
experience.
Figure 1. Example of the TM040040 Trackpad - Component View
This document describes the mechanical and electrical specifications for the TM040040
trackpad solution. It also describes how an external host controller can interface with the Cirque
TM040040 solution using either the SPI or I
2
C protocol. Suggested design considerations are
also covered.
Benefits
Cirque's latest generation of trackpads define the standard for the pointing device industry.
These solid-state devices are extremely durable because they have no moving parts to clog or
break down. The trackpad's compact size, thin profile, and low weight, allow it to be easily
designed into a variety of OEM products. These features, as well as the following benefits, make
the TM040040 an ideal solution for integration.
• Built in precise positioning
• No moving parts - high reliability - durable
• Advanced features embedded in hardware
• Environmentally sealable design
• Adaptable and collaborative support is
offered for integration
• No contact pressure required
• Compact size, thin profile, and lightweight
• Low stress / low fatigue operation
• Power saving operation modes
• Built on Cirque's vast experience of providing
innovative technology
Cirque GlidePoint

trackpads are based upon patented mutual capacitance technology, which
provides smooth and precise cursor control. A sophisticated sensing array is below the
trackpad's durable surface, which accurately responds to even the smallest finger movements.
No finger pressure is required. Simply move a finger across the trackpad to move the cursor.
