概要

The FingerTip FTG2-SLP provides an optimal mix of low power, small size, low external part counts and versatile features with unmatched true multi-touch performance in a single-chip touchscreen controller for thin flexible embedded display-touch panels.
The FingerTip FTG2-SLP uses a dedicated differential architecture with capacitance to current acquisition engine to implement the touch sensing. Coupled with the internal processor the Fingertip touchscreen controller can detect, classify and track 10 fingers touch with fast report rate and response times with a configurable channel matrix consisting of total 21 TX and 40 RX channels.
The touch acquisition analog front end has a wide dynamic range able to cope with panels of different size and configuration. This offers great flexibility to use FingerTip with new technology of embedded display-touch panels that are thinner and flexible. The FingerTip FTG2-SLP provides support for flat or curved displays through proprietary differential and node compensation hardware coupled with differential data processing techniques in firmware.
The FingerTip FTG2-SLP low-noise differential capacitive analog front-end provides enhanced noise suppression capabilities for various noise sources such as high resolution display, 3-phase noise and severe common mode noise introduced by battery chargers.
The FingerTip FTG2-SLP uses hardware and firmware ST proprietary techniques to reduce power in active and idle modes.
The FingerTip FTG2-SLP device incorporates multiple TX driving methods that can further boost the SNR and report rate.
The FingerTip FTG2-SLP supports advanced features thanks to the multi-mode sensing technology. The water rejection algorithm can detect water on the top of the screen and the device can still track one finger moving in the water without false touch or line breaking. The device supports multi finger glove operation and 2.5mm passive stylus. The device supports 20mm stable capacitive proximity.
The device also incorporates hardware SYNC on GPI3 pin which enables the touch sampling to be synchronized with the display SYNC signal. This enables it to work even with Quad High Definition displays. The device can also work in Non-SYNC condition.
The main processor implements a powerful 32-bit ARM M4 core with 192KB Flash that is able to provide a high level of overall touch performance in terms of noise rejection, response time and power consumption. It is running concurrently to the analog front end and gives ample scope for implementation of complex sensing touch tracking algorithm, advanced shape based filtering and event reporting. The 192KB flash size provides enough free space in the Flash for further customization even after implementation of ST firmware for all the features.
The device supports I2C serial interface and SPI slave interface for more flexibility.
