Microchip MTCH6303 touchscreen controller

Sept. 3, 2015 – Microchip Technology has added the MTCH6303, a turnkey projected-capacitive touch controller for touch pads and screens, to its Human Interface Solutions portfolio. Touch sensors with up to 1000 nodes and diagonals of up to 10 inches are supported.

The MTCH6303 provides multi-touch coordinates as well as a readymade multi-finger surface gesture suite that offers pinch and zoom, multi-finger scrolling and swipe interface elements. Its signal processing provides noise-avoidance techniques and predictive tracking for 10 fingers, at scan rates of up to 250 Hz with a minimum of 100 Hz each for five touches. It also combines with Microchip’s MTCH652 high-voltage line driver to achieve a “superior signal-to-noise ratio (SNR) for outstanding touch performance in noisy environments,” notes the company.
