PI5USB30216DXUAEX

PI5USB30216DXUAEX is a USB switch/multiplexer in the PI5USB family from Pericom (now Renesas). It provides programmable routing of USB data lines, enabling multiple USB ports to be connected to a single host or hub controller. It’s typically used for USB port expansion, hub/switch implementations, or device isolation for power/bandwidth management. The device is controlled via a serial interface (I2C/SMBus or SPI) and includes features such as port isolation, VBUS control, ESD protection, and low on-resistance data paths to preserve signaling integrity. The “16” in the part name indicates the size of the configurable crosspoint (number of ports/channels); “DXUAEX” is the specific package and temperature‑grade code. Applications include USB hubs, docking stations, and embedded/industrial or automotive USB solutions. For exact electrical specs, pinout, timing, and control commands, consult the official Renesas/Pericom datasheet and application notes.

Here are typical features of the PI5USB30216DXUAEX (USB switch/mux device):
- 2-channel USB 2.0 high-speed crossbar switch (D+/D−) for host/device routing
- Allows one host to connect to one device via configurable 2:1 switch
- Control via simple EN/SEL logic pins for port selection
- Hot-swappable operation with per-port protection
- Integrated ESD protection on USB data lines
- Per-port overcurrent protection
- IOs and controls compatible with common logic levels; 5V-tolerant data paths
- Low power/low quiescent current with suitable standby behavior
- Small 16-pin DXUAEX package (suitable for compact boards)
- Applications: docking stations, USB hubs/switching, portable devices, motherboards
Note: For exact electrical specs (voltage ranges, current limits, timing, and package details), please consult the latest datasheet from Renesas/Pericom.

- Pin count: 32 pins (QFN package).
- Function: USB switch/crossbar (PI5USB family) that routes/multiplexes USB data lines between ports (USB 2.0/3.0), used for port-switching in USB hub/type-C applications.

- Manufacturer: Renesas Electronics Corporation (the PI5USB family originated with Pericom Semiconductor, which Renesas acquired).
- What kind of company: A Japanese multinational semiconductor company that designs and manufactures integrated circuits and connectivity ICs (MCUs, analog/power, USB/PCIe switches) for automotive, industrial, and consumer markets.

- USB 2.0 data-path switching/muxing between host and device or across multiple ports
