STMicroelectronics unveils Resistive Multi-Touch Single-Chip Controller

STMicroelectronics has introduced a very advanced multi-touch ‘resistive’ touchscreen controller chip to optimize the Bill of Materials of the electronics supporting this advanced capability. The STM32TS60 is the first member of ST’s new STMTouch family, which offers a broad portfolio of solutions including multi-touch devices and proximity and touch-key sensors.

The STM32TS60 single-core microcontroller is an added-value solution compared to other expensive multi-core processor or digital signal processors (DSPs) requiring specialized programming expertise. 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 conceived for power-sensitive embedded applications. In addition, very-low-power idle mode with ‘wake-up on touch only’ helps further extend mobile battery life.

The STM32TS60 is housed in a 7 x 7mm 144-pin UFBGA package, and is now sampling to lead customers. Volume production is expected for Q2 2010.
