USB5744-I/2G
Microchip’s USB5744 SmartHub™ IC is a 4 port, SuperSpeed (SS)/Hi-Speed (HS), low power, low pin count configurable and fully compliant with the USB 3.1 Gen 1 specification. The USB5744 also supports Full Speed (FS) and Low Speed (LS) USB signaling, offering complete coverage of all defined USB operating speeds. The new SuperSpeed hubs operate in parallel with the USB 2.0 controller, so 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic.
The USB5744 is in a 0.4mm pitch, 56 pin QFN. It's the smallest 4 port USB 3.1 Gen 1 hub in the industry. Functionality was reduced to optimize pin count and provide a cost effective solution.
SmartHub ICs are defined as a USB hub that integrates system levels functions typically associated with a separate MCU or processor. Microchip’s USB5744 Smart Hub support custom configurations of external ports and GPIO pins. MPLAB Connect Configurator, Microchip’s proprietary software utility, can be used to program On-chip One Time Programmable (OTP) ROM which stores required register settings to ensure the desired start up configuration at power on. All port control signal pins and GPIOs are under firmware control, allowing for maximum operational flexibility. However, for even more simplicity, the USB5744 can be configured through a series of external low-cost resistor bootstraps. No OTP programming required.
Microchip的USB 5744 smart hub IC是一款4端口、超高速(SS)/高速(HS)、低功耗、低引脚数的可配置产品，完全符合USB 3.1 Gen 1规范。USB5744还支持全速(FS)和低速(LS) USB信号，完全覆盖所有定义的USB操作速度。新的超高速集线器与USB 2.0控制器并行操作，因此5 Gbps超高速数据传输不受较慢的USB 2.0流量的影响。
USB5744采用0.4毫米间距的56引脚QFN。这是业界最小的4端口USB 3.1 Gen 1集线器。减少了功能，以优化引脚数并提供经济高效的解决方案。
SmartHub ICs被定义为USB集线器，它集成了通常与独立MCU或处理器相关的系统级功能。Microchip的USB5744智能集线器支持外部端口和GPIO引脚的定制配置。MPLAB Connect Configurator是Microchip的专有软件实用程序，可用于对片内一次性可编程(OTP) ROM进行编程，该ROM存储所需的寄存器设置，以确保上电时所需的启动配置。所有端口控制信号引脚和GPIOs都受固件控制，从而实现最大的操作灵活性。然而，为了更加简单，USB5744可以通过一系列外部低成本电阻自举进行配置。不需要OTP编程。
