Data Acquisition - Touch Screen Controllers

The CP8461ATT is a touch screen controller designed for a variety of applications in an array of markets. It is a highly reliable, low-cost, low-power controller with advanced features, making it ideal for use in demanding industrial applications. The device is compliant with multiple touch screen technologies, including capacitive and surface acoustic wave (SAW). In addition, the product features a wide range of configurable settings, such as in-demand functionality, touch event types, noise immunity, and performance levels. Additional features include integration with multiple communications interfaces, such as UART, I2C and USB.

The CP8461ATT is a very versatile product with a wide range of applications due to its unique features. It can be used to control motion and other types of physical systems. It can also be used as an input device, providing precise and reliable finger tracking capabilities. In addition, it enables the development of touchscreen user interfaces for any kind of application. Due to its low power profile, the device can be used in battery-powered systems, especially handheld and mobile devices. It is also an excellent choice for point-of-sale (POS) systems, interactive kiosks, and the gaming industry.

The CP8461ATT is designed to be used in both capacitive and SAW touch screen technologies. The capacitive touch screen technology is based on a sensing technology that measures the properties of an electrical field to detect the presence of a finger. The technology utilizes sensors that are placed around the touch screen to create a field. Whenever a finger touches the sensor, the electrical field is disturbed and an output is generated. This output is then used to detect the position, shape and size of the finger on the touch screen.

The SAW technology utilizes high-frequency sound waves to detect and track finger motion on a touch screen. The SAW sensors are mounted around the display and create a network of sound waves. As the finger touches the sensor, the waves are disrupted and the controller can detect the position and size of the finger. This technology is historically more reliable and accurate than capacitive touch screens, and can detect multiple touches at once.

The CP8461ATT is designed to deliver high accuracy, low power consumption and fast responses. It is powered by a low-voltage power supply, ranging from 2.5 V to 3.3 V, making it ideal for mobile and wearable applications. The device features integrated self-calibration capabilities, which means it can automatically re-calibrate itself whenever an external environment change is detected, allowing it to maintain a high level of accuracy. The device includes two separate signal paths, allowing it to identify and process signal information faster and more accurately than traditional single path controllers.

The CP8461ATT is equipped with multiple communication interfaces. It supports both I2C, UART, and USB protocol. It is also compatible with multiple digital signal processor (DSP) platforms, allowing integration with embedded digital signal processing systems. The device comes with a wide range of onboard resources, including digital touch recognition and signal processing engines, and a touch screen controller and driver.

The CP8461ATT controller offers a wide range of features and performance levels, and is suitable for a variety of applications in multiple markets. It is a highly reliable, low-cost, low-power and highly configurable touch screen controller that can be seamlessly integrated into a range of systems and embedded platforms. Thanks to its advanced features, it can provide an ideal solution for a variety of touch and motion sensing applications in industrial and consumer electronics.
