SU748
Contents
Description
This module provides a super speed USB3.0 Interface for the LogicBox in association with the Cypress FX3 USB3.0 controller. Due to the 32-Bit parallel Data-BUS, the submdoule was designed as a double SU-Board with two SU-Connectors. The hole board can be supplied by the +5V-supply of the USB-Port or the +5V-supply of the LogicBox. To protect the FX3 controller against a faulty VBUS voltage from the USB-Port, the USB charger port protection chip TPD4S014 was used. The FX3-Chip provides several serial interfaces like I²S, I²C, SPI and UART to connect to external peripherals. With the implemented I²C register PCA9555 configured by I²C or the 8-Pin DIP-Switch, some status information can be displayed on eight LEDs at the frontpanel.
