Microchip コントローラIC 1ポート USB5734-I/MR 5 Gbps USB 3.0 3.6 V, 64-Pin SQFN

The USB5734 integrates functions that would typically be associated with a separate MCU or processor; as such Microchip classifies this device as a ’Smart Hub’. For example the device can communicate to peripherals via I2C, SPI, GPIOs or UART in addition to USB. Also a downstream device can take control of the host system by swapping roles to become the host port, with the Smart Hub switching between two different hosts if required.

Integrated Hub Feature Controller (HFC) enabling I/O bridging and FlexConnect

I/O Bridging: Host communication to external peripherals - USB to I2C/UART/SPI/GPIO

FlexConnect: Host port swapping and switching to downstream devices

Battery Charging: USB-IF revision 1.2 support on downstream ports (DCP, CDP, SDP)

Simultaneous data transfer for 2500 mA of high speed charging

Port Configuration Straps: Predefined configuration of port settings – Battery Charging, Non-Removable, Disable

Application Straps: Predefined configuration of GPIOs for specific Use Cases including Mixed Mode, FlexConnect Mode, Port Speed mode, Port BC Mode and UART Mode.

ProTouch2: Configuration tool to enable enhanced OEM configuration options through either One-Time Programmable (OTP) (8Kbit) or external SPI ROM
