Product Summary

The AT42QT2160-MMU (QT2160) is a 16-key QMatrix Sensor IC. The AT42QT2160-MMU (QT2160) is designed for use with up to 16 keys and a slider (constructed from 2 keys up to 8 keys). There are three dedicated General Purpose Input/Outputs (GPIOs) which can be used as inputs for mechanical switches etc. or as driven outputs. There are eight shared General Purpose Outputs (GPOs) (X0...X7) which are driven outputs only. There is PWM control for all GPIO/GPOs.

Parametrics

AT42QT2160-MMU absolute maximum ratings: (1)Address space: 7-bit; (2)Maximum bus speed (SCL): 100 kHz; (3)Rise times on SDA and SCL: 1 μs maximum.

Features

AT42QT2160-MMU features: (1)Number of keys: up to 16 keys, and one slider (constructed from 2 to 8 keys); (2)Number of I/O lines: 11 (3 dedicated - configurable for input or output, 8 shared - output only), PWM control for LED driving; (3)Technology: patented spread-spectrum charge-transfer (transverse mode); (4)Key outline sizes: 6 mm x 6 mm or larger (panel thickness dependent); widely different sizes and shapes possible; (5)Key spacings: 8 mm or wider, center to center (panel thickness dependent); (6)Slider design: 2 to 8 keys placed in sequence, same design as keys; (7)Electrode design: two-part electrode shapes (drive-receive); wide variety of possible layouts; (8)PCB layers required: one layer (with jumpers), two layers (no jumpers); (9)Electrode materials: PCB, FPCB, silver or carbon on film, ITO on film; (10)Panel materials: plastic, glass, composites, painted surfaces (low particle density metallic paints possible); (11)Adjacent metal: compatible with grounded metal immediately next to keys; (12)Panel thickness: up to 3 mm glass, 2.5 mm plastic (key size dependent); (13)Key sensitivity: individually settable via simple commands over I2C-compatible interface.
