STM32TS60: Multitouch screen controller device using a digital resistive touchpanel with I²C, SPI, UART and USB interfaces

The STM32TS60 product is a multitouch controller device based on Stantums 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.

STM32TS60主要特点:

■ Patented digital resistive multitouchpanel technology powered by PmatrixTM firmware engine

■ Able to track up to 10 independent touches simultaneously

■ Finger, nail and any stylus touch capability

■ Up to 0.17 mm resolution

■ Touch actuation force information

■ No calibration requirements

■ Typical touchpanel scan rate of 125 Hz up to 250 Hz

■ Single- or dual-chip architecture able to support up to 10.1” screens

■ Single-chip controller able to support up to 129 rows/columns coming from the sensor matrix.

■ Embedded compensation resistors for reduced BOM and easy connection to the touchpanel

■ I2C, SPI, UART and USB communication interfaces

■ Very low power mode allowing “wakeup on touch/release” mode

■ Wakeup response time: 10 μs from Sleep mode and 100 μs from Standby mode

STM32TS60应用:

■ Gaming devices

■ Mobile handsets

■ Smart phones

■ Portable media players

■ Personal navigation devices

■ Mobile internet devices

■ Netbooks
