Microchip launches MXT2952TD 2.0 family of secure touchscreen controllers

Microchip Technology has launched the MXT2952TD 2.0 family of secure touchscreen controllers. The company said, ‘Typical touch-enabled human machine interface and radio frequency identification combination-based payment systems are vulnerable to hacking attacks via malicious software updates or man-in-the-middle attacks when a user enters their personal identification number on the touchscreen. Physical mesh barriers and sensors are often used around these integrated circuits for protection from hacking. Constant reflashing of software and device resets are used to help safeguard software integrity. The MXT2952TD 2.0 family is designed to encrypt touch data and cryptographically authenticate software updates to minimize risk and meet PCI certification compliance standards. When the RFID reader IC and the touchscreen controller are on different printed circuit boards, it is especially difficult and expensive to build physical barriers for hack protection. Embedded firmware on the MXT2952TD 2.0 provides a more easily implemented solution for EV charger manufacturers to remain compliant with security regulations and avoid the cost of adding a second, expensive touchscreen payment module to the charger.”
