The ATMXT1188S from Microchip Technology, Inc. is a maXTouch touchscreen controller designed for high-performance applications. It supports two touchscreens with true 12-bit multiple touch reporting, capable of handling up to 16 concurrent touches per screen. The device accommodates screen sizes ranging from 8 to 12.1 inches with a 5 mm electrode pitch and offers flexible grid configurations of up to 32 X and 52 Y lines, allowing for a maximum of 1188 channels. This controller features advanced digital filtering, self-calibration, and noise cancellation algorithms, ensuring reliable performance even in noisy environments. It supports various sensor types, including PET and glass, and is compatible with stylus inputs. The operating temperature range is from -40¬8C to +85¬8C, making it suitable for diverse applications. The ATMXT1188S communicates via an I¬=C-compatible interface and USB 2.0, with a power supply range of 1.8V to 6.0V depending on the configuration. Its compact 128-ball VFBGA package measures 7 x 7 mm, facilitating integration into space-constrained designs. This product is ideal for applications requiring high touch accuracy and responsiveness, such as tablets and e-Readers.
The recommended alternative touch controller is ATMXT1066T2.
