STMicroelectronics (Geneva, Switzerland) has introduced the STM32TS60, a single-chip multi-touch “resistive” touchscreen controller that detects up to 10 simultaneous touches with fingers, nails, or stylus, enabling designers to replace complex sequences with user controls. The controller combines STM32 microcontroller architecture with PMatrix™ multitouch technology from Stantum. The STM32TS60’s high EMI immunity makes it suitable for use in multi-function wireless products such as cellphones, notebook PCs, netbooks, and mobile Internet devices. Moreover, its low power consumption helps to maximize operating times and recharge intervals, and is a direct benefit of the STM32’s energy-saving design features and ARM® Cortex™-M3 processor. In addition, very-low-power idle mode with ‘wake-up on touch only’ helps further extend mobile battery life. It is housed in a 7mm x 7mm, 144-pin UFBGA package.
