Projected Capacitive Controller & Firmware

What type of capacitance sensing technology do PenMount PCI touch controllers employ?

PenMount PCI touch controllers employ mutual capacitance sensing with sensing and driving lines in the touch panel’s two conducting layers sensing touch location.

What types of controllers can PenMount provide?

PenMount can provide three controller types including control board, COF, and IC solutions.

Which IC do PenMount PCI touch controllers use?

PenMount PCI touch controller use the PenMount P2 series controller IC.

Which vendor supplies PenMount controller microprocessors? Can these microprocessors be purchased directly from the vendor?

PenMount controller chips are proprietary and include PenMount firmware.  Please contact us with your requirements.

What is COF?

COF (Chip on Flex) refers to soldering the PCI touch controller directly to the FPC tail.

Which host connection interfaces do AMT PCI COF support?

We can provide USB, UART, and I2C interfaces.

What are the advantages of COF?

By integrating the controller IC into the touch panel, less space is required in the mechanism design.  The FPC can be designed to various lengths, widths, and curvatures to facilitate assembly in small product.  COF does not require touch panel end connectors and cables.

Can PenMount provide customized PCI COF controllers?

Yes, PenMount provides custom COF design.

Can PenMount support customers designing PCI touch ICs directly onto their motherboard?

Yes, please contact AMT sales representatives for relevant requests.

How many touch points can PenMount PCI controllers support?

PenMount PCI controllers can support a maximum of 10 touch points.

Can PenMount PCI controllers support noise immunity, gloved operation, thick glass, and water handling functions simultaneously?

Yes, PenMount PCI controllers offer noise immunity, gloved operation, thick glass, and water handling functions in one firmware.

What are the EMC standards met by PenMount PCI touch controllers?

The latest generation of PenMount PCI touch controllers can pass IEC 61000-4-3 Radiated Susceptibility (RS) Level III 10V/m and IEC 61000-4-6 Conducted Susceptibility (CS) Level III 10Vrms testing standards.

How are PenMount’s “WP” and “WD” water handling modes defined?

WP (Water Performance):

When there is water on the touch panel surface, no false touch signals are generated in wet areas and single touch operation is available in dry areas.  Once the touch panel is dried, normal touch operation is automatically restored.

WD (Water Detection):

When there is water on the touch panel surface, the controller automatically suspends touch functions.  Once the touch panel is dried, normal touch operation is automatically restored.

How is the calibration procedure performed on a PenMount PCI controller?

PenMount PCI controllers do not require calibration.  The only requirement is matching screen rotation angle for all operating systems.

Can PenMount controllers support PCI panels optically bonded to LCDs?

Yes, we recommend LED backlit LCD panels.  Before selecting your LCD, we suggest confirming the strength of EMI interference emitted LCD options to assess whether an EMI shielding layer must be added to the touch panel.

Are there any restrictions when designing PenMount controller assembly mechanisms?

Please reference your integration guide.

Does PenMount provide firmware customization services?

Yes, please contact us.

Can PenMount PCI touch controllers be paired with PCI touch panels produced by manufacturers other than AMT?

PenMount PCI controllers can be paired with any PCI touch panel meeting PenMount controller design standards.

Can AMT provide controllers that are not PenMount controllers?

AMT is currently working with ATMEL and will soon be able to provide an Atmel touch solution.

What is the sample rate of PenMount PCAP products?

100 Hz @ 5 points

How do PenMount PCAP products replace mouse devices?

Install the PenMount driver.

When PenMount PCAP products use I²C or UART, is 3.3V supported?

Yes, please contact our sales representatives.

Must System Reference (SR) be built manually and individually for each PenMount PCAP product?

The purpose of building SR is to find the best firmware processing solution for controller and panel pair.  After enabling water handling, SR can increase the range of supported temperatures.

PenMount PCAP products can support different interfaces (USB, I²C, UART, and RS232. Can I connect two or more interfaces at the same time?

Standard firmware does not support connecting two or more interfaces simultaneously.  If you need to do this, contact AMT sales personnel and we will create a customer firmware version to support this request.
