2.2.2 Digital Interface
The digital interface connects the host PC with the EVK board. The interface is implemented on the
EVK board using an MCU and a micro-USB connector.
Micro-Controller Unit (MCU)
Cypress’s EZ-USB FX3™ MCU integrates the USB 2.0 physical layers (PHYs), and contains a 32-bit
ARM926EJ-S microprocessor for building custom USB SuperSpeed applications. The integrated
processor contains a unit called General Programmable Interface (GPIF), which provides easy
connectivity to popular interfaces.
USB Connector
The onboard micro-USB-B 2.0 connector is used for power supply and for data transfer between the
sensor unit and the host PC. The connector supports the USB 2.0 protocol in High-Speed Mode (480
Mbps).
