The ATMXT1386E-Z2U is a capacitive touch screen controller from Microchip Technology's maXTouch family. It supports up to 1386 channels, enabling high-resolution multi-touch interfaces for large displays. The device integrates a 32-bit resolution processor and communicates via I2C or USB interfaces. It utilizes a proprietary charge-transfer acquisition engine for robust signal detection. The component is classified as a touch screen controller within the data converter ICs sub-category.
Verify current availability status as the component is listed as obsolete in public distributor records. Confirm RoHS compliance details directly from the manufacturer datasheet before integration. Check for end-of-life notifications and recommended replacement strategies due to discontinuation status.
Select this controller for designs requiring extensive touch node support beyond standard single-digit touch controllers. Ensure interface compatibility with host systems supporting I2C or USB protocols. Consider the 32-bit resolution requirements for precision tracking needs in large form factor displays.
This part belongs to the maXTouch series of capacitive touch controllers. It is distinct from lower-channel variants like the MXT144 or MXT1066 by its significantly higher channel capacity. The Z2U suffix indicates specific packaging and tape-and-reel configuration options available for this model variant.
Public sources list the ATMXT1386E-Z2UR as a related variant with different packaging quantities. No direct functional pin-to-pin replacements are confirmed in public documentation. Evaluate newer maXTouch models with similar channel counts for long-term supply stability.
