The ZT7538 is a 5th generation capacitive touch screen controller vitalizing the transparent capacitive touch screen panel. New hybrid and high voltage drive AFE engine provides better wet touch, glove touch and stylus pen performance with higher SNR and two different types of capacitive data driven by mutual and self-sensing methods. In addition, the embedded hardwired touch-detection engine is able to minimize power consumption in idle mode during the system is suspended. The system can be revoked by user-defined gestures which can be programmed on the user space NVM embedded on this controller. It also includes all signal processing algorithms to provide the versatile filters to cope with various LCD types, noises and user-defined scenarios.
This controller has 38 channels which can be configurable to 24 Tx by 14 Rx for the portrait type of display device. It supports wide I/O voltage level which can accept the various voltage level of I/O in HOST CPU so that it can be compatible with almost all HOST CPU for the mobile applications. For HOST CPU communication, it provides I2C interface with up to 1MHz of I2C clock speed which is the fastest in I2C specification.
It is packaged in QFN to provide stable soldering on FPC (Flexible Printed Circuit) module. No external components except bypass filter capacitors for the power supply are needed.
Zinitix has various touch controllers for from small devices like smart watch to large devices such smart phone and tablet.
