CY8CTMA884
CY8CTMA616
SUMMARY
Automotive TrueTouch® Multi-Touch
All-Points Touchscreen Controller
General Description
CY8CTMA884/CY8CTMA616 is a single-chip solution for touchscreen applications. It delivers up to 884-node, high-performance,
mutual-capacitive sensing for screen sizes of 5.5-inch to 11.6-inch designs. It employs TrueTouch® Multi-Touch All-Points sensing to
track up to 10 fingers simultaneously with no ghosting, and delivers up to 100-Hz refresh rate with 0.5-mm accuracy.
