Description
1.1
Device overview
The STM32TS60 product is a multitouch controller device based on Stantum's patented
digital resistive multitouch technology. This technology employs the connectivity power of
the universal serial bus (USB) with Cortex™-M3 processors and ARM architecture.
Conventional resistive touch controllers are unable to detect more than one contact at a
time. Thanks to the STM32TS60 device, it is possible to detect and track up to ten contacts
over a touchpanel. The STM32TS60 delivers an exact image of what is happening on the
touchpanel surface in the most reliable way with very fast response time and with high noise
immunity performances.
1.2
Main benefits
The STM32TS60 represents a breakthrough over competing technologies, bringing
outstanding multitouch performance with the best power budget.
The resistive technology does not require any panel scan during Standby. Consequently, the
STM32TS60 device has very low standby power consumption. In addition, this device
benefits from the industry-leading mW/MIPS power performance of the ARM Cortex-M3
core.
1.3
Other benefits
●
Unique resistive true multitouch technology with up to 10 touches at a time
●
Finger, nail and any stylus touch capability
●
Fingers actuation force detection based on linear measurement of the touch area
surface variation
●
High responsiveness with low power consumption (at standby, near zero consumption)
●
Homogeneous sensitivity on all points of the touchpanel area
●
No calibration
●
IP protected by solid patents based on proven resistive technology with very powerful
EMI (electromagnetic insulation).
●
Very low power Standby mode and zero power resistive panel
●
Panel adapted from the proven high-volume resistive technology; able to reach high
durability and 90 % transparency.
