描述 Description

The recommended alternative touch controller is?ATMXT336U.A 224-node highly configurable touchscreen controller that is part of the Microchip maXTouch product platform. An optimal and scalable architecture enables smart processing of a capacitive touch image to accurately regenerate and report the user's interaction with the touchscreen. Multi-touch performance identifies and individually tracks touches and allows a range of built-in gestures to be reported to the host processor. The IC provides position data of 12-bit x 12-bit resolution, as well as information on the size and angle of touch. Position data is reported at >250Hz, providing fast and smooth finger tracking, making it suitable for use with demanding applications such as handwriting recognition. Due to the high signal-to-noise ratio (SNR) of up to 80:1, the device works well with fingertip touch and can also be used with a conductive stylus. It is designed to work in demanding, rapidly changing environments. Only the touchscreen area is touch-sensitive, allowing design freedom to place the chip on the main board or adjacent to the sensor. The device is ideally suited to mobile phone-sized touchscreens and can also be used on screens of up to 7\", supporting single-touch or two-touch with a larger finger separation.Support: off the shelf maXTouch standard modules are available to help shorten development time and reduce risk. Microchip also has a strong selection of factory trained global touch sensor module partners to help support custom touch sensor and/or touchscreen display designs.

簡介

ATmXT224屬于集成電路（IC）的傳感器電容式觸控。由制造生產(chǎn)的ATmXT224傳感器，電容式觸控該系列產(chǎn)品提供操作電容式觸摸感應(yīng)傳感器所需的模擬激勵和測量資源，并以一種便于微控制器或類似器件使用的格式（例如 I2C 或 SPI 串行接口、UART 或簡單的邏輯信號）來傳遞由此產(chǎn)生的信息。這些器件常用于人機(jī)界面應(yīng)用。
