CP8412AT

CP8412AT is a touch screen controller. It is mainly used for data acquisition. It is based on the MWCOC microcontroller, a RISC machine core with powerful performance, which has very low power consumption for various types of microcontrollers.

CP8412AT features an interface compatible with a wide variety of external touch screen systems. The use of this kind of touch screen controller can greatly reduce the data acquisition time and more reliably detect the contact between the finger and the touch screen.

The working principle of CP8412AT is mainly based on the principle of capacitance. When the finger touches the touch screen, a capacitive element is formed, which will bring a capacitance variation to the screen. If a steady potential is applied to the screen, a current flow will be generated between two electrodes, and the touched position is marked by measuring the current change.

The CP8412AT touch screen controller also adopts the special technology of auto-calibration of distributed capacitance to make the touch sensitivity of the same point remain constant within the entire range of the touch screen. Its touch accuracy can achieve the level of 1mm or 0.4mm.

In terms of application field, CP8412AT touch screens can be found in a wide range of products, from consumer electronics and automotive cockpits, to industrial and medical applications. For example, they are commonly used in GPS navigation systems and medical instruments, such as ECG systems.

CP8412AT is one of the most advanced touch screen controllers available. It features low power consumption and high accuracy, which make it ideal for a variety of applications. With its low cost and high performance, it has become a popular choice for many electronic products.
