PenMount COF PM2203B meets EMC CS/RS Level III Specs

03/17/2016 | Bulletin No. : PMY16003

PenMount continues to focus on the R & D of projected capacitive (PCI or PCAP) touch controller technology and breaking through bottlenecks to provide customers with superior functionality. This is the target of PenMount’s efforts.

When we see customer application requirements for mid/small size products such as portable products and touch applications for automotive tablets, our design goal is a light and thin appearance. In situations where mechanism space is relatively limited, customers normally use a COF (Chip On Flex PCB) controller design in PCI products. Of course, in industrial and medical products, customers also require anti-interference functionality, an ability to achieve basic specification requirements whether in conducted noise tolerance or radiated noise tolerance.

PenMount’s 3rd generation COF controller PM2203B supports small 5″-7.9″ PCI touch panels. This controller has successfully passes IEC 61000-4-3 RS Level III and IEC 61000-4-6 CS Level III 10V testing standards, can provide customers with improved noise immunity, and reduces the chances of false touch signals caused by interference. The entire series of standard 3rd generation PenMount PCI controller products, the PenMount PM2203B and PCB Control Board controllers (including PM1210/ PM1310/ PM1410/ PM1710/ PM1711), can also achieve a level of performance equivalent to EMC RS/CS Level III 10V.


In terms of function, PenMount’s proprietary firmware, hardware, and software not only satisfy customer requirements, but also allow customers to quickly achieve marketable applications. The noise immunity specifications of our PM2203B paired with a AMT P3012-C2D 7″ PCI touch panel has increased significantly while retaining 5-point touch operation and supporting 1.1mm, 1.8mm, and 2.8mm cover glass thicknesses. Firmware design allows PCI touch panel water handling to maintain an excellent reliability threshold of “No False Touch When Wet.” USB, UART, and I2C interfaces are provided on the PM2203B COF hardware and the firmware version PM2203B.1.1.0 supporting EMC RS/CS level III has already been released. The PMUpdate firmware update utility provided by PenMount can be used to upgrade to the latest firmware version, allowing your controller to obtain an EMC RS/CS Level III standard without changing hardware architecture.

As the PCI touch application field becomes increasingly ubiquitous, PenMount’s design philosophy is to consider further on behalf of customers. PenMount provides customers with reliable and convenient touch products. Flexible service has always been PenMount’s core value. In addition to the relentless upgrade of hardware and firmware, we also provide easy to use utilities for software support. PenMount offers comprehensive touch solutions to assist customers in successful integration into product mass production. If your product requires other PCI touch panel designs or must be paired with thicker cover glass, you are welcome to contact us. We will provide you with the suitable services.
