This technology has enabled developers to create high-resolution touch-enabled displays that can offer seamless integration for embedded applications. It offers an attractive cost-effective solution for a wide range of touch-screen applications from consumer electronics to medical, automotive, and industrial markets.

The SX8650ICSTRT controller is a low-power touch controller used to capture single-touch data points with accuracy even in noisy environments. It integrates a capacitive touch sensor and a digital filter, which are optimized for low latency and good touch accuracy. The controller offers various performance-enhancing features such as noise-filtering, continuous tracking, temperature compensation, and adjustable parameters. The integrated processing units can be loaded and updated over the air.

The controller has an embedded low-power controller with an 8-bit microcontroller and operates on a wide range of input designs including single-channel sensors, dual-channel sensors, and linear and rotary axis sensors. It features enhanced active power management, allowing for battery powered applications and low-voltage operation. In addition, it supports industry standard sensing protocols including the space vector and force detection methods.

The SX8650ICSTRT controller is primarily used in applications requiring finger input, such as tablets and other touch-enabled devices. It is designed for quick response times and accurate finger recognition, offering excellent accuracy even with fast-moving fingers. It features a low-power consumption design for long-term operation and improved signal-to-noise ratio. Additionally, it supports a wide range of finger-tracking algorithms, allowing for the detection of finger movements in different directions, including diagonal, circular, and curved motions.

The primary working principle of the SX8650ICSTRT controller is centered on capacitive touch technology. The controller operates on the principle of detecting and measuring the changes in electrostatic capacitance. Specifically, the controller detects changes in capacitance levels between two or more electrodes at its input and determines whether a finger has been touched. The capacitive sensing array of the controller consists of two layers, with one acting as a transmitter and the other as a receiver. When a finger touches the receiver, an electrical current is generated that is measured. This current is then used to determine the position of the finger.

The SX8650ICSTRT controller is an effective and reliable solution for touch-enabled applications. It features low-power operation, high accuracy, and fast response times. Additionally, it offers a cost-effective solution for a wide range of touch-enabled audio and video applications from consumer electronics to medical, automotive, and industrial markets. As a result, it is a versatile and efficient touch controller well-suited for a range of embedded applications.
