PAP1100QN: Low Power 10 Touch Controller
Description
The PAP1100QN is a low-power, 10-touch controller designed specifically to provide a touch screen system with high report rate, touch accuracy, and responsive on-screen navigation, with very low latency. The IC uses a mutual- capacitance measurement technique, where it senses capacitance changes on the touch panel, and detects multiple touch points simultaneously. The PAP1100QN touch controller is designed specifically for applications in a high-noise environment. It is robust against common-mode, display, and RF noise; thereby eliminating the need for a Ground shield on the touch panel, reducing system cost. Its high-density drive/sense lines support touch screens up to 5”, with 10 simultaneous touch points. A passive stylus is also supported. Larger screens can also be supported where fine-cell spacing is not a priority. The low-power design is ideal for extending battery life. Programmable power modes include: Run mode [150 Hz report rate, 1 TP] 25 mW Run mode [150 Hz report rate, 5 TPs] 30 mW Shutdown 145 μW Additional programmable Idle/Rest modes are also available. There are 30 kbytes of Flash memory for Pixart supplied based-line operational code storage. In addition, there are 2 kbytes of Flash memory for application-specific data storage, such as saved register settings, customized configurations of drive/sense mapping, buttons, sliders and haptics. There is no overlap between the 30 kbytes and 2 kbytes spaces. The controller IC operates from a single 1.72 – 2.0 V or 2.5 – 3.6 V supply voltage, with I/O voltage from 1.6 to 3.6 V. The part is housed in a 6 x 6 x 0.55 mm 48-pin TQFN package.
