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.
