USB5744/2G
Product Description
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.
产品简介
Microchip的USB5744 SmartHub™IC是一个4端口,超高速(SS)/高速(HS),低功耗,低引脚数可配置,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,提供所有定义的USB操作速度的完全覆盖。新的SuperSpeed集线器与USB 2.0控制器并行运行,因此5gbps的SuperSpeed数据传输不受较慢的USB 2.0流量的影响。
USB5744采用0.4mm间距,56引脚QFN。这是业界最小的4端口USB 3.1 Gen 1集线器。减少功能以优化引脚数,并提供具有成本效益的解决方案。
SmartHub ic被定义为一个USB集线器,它集成了通常与单独的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引脚的自定义配置。MPLAB连接配置器是Microchip的专有软件实用程序,可用于对片上一次性可编程(OTP) ROM进行编程,该ROM存储所需的寄存器设置,以确保开机时所需的启动配置。所有端口控制信号引脚和gpio都在固件控制下,允许最大的操作灵活性。然而,为了更简单,USB5744可以通过一系列外部低成本电阻引导配置。不需要OTP编程。
