PI5USB30216CXUAEX

PI5USB30216CXUAEX is a part in Renesas’ PI5USB family. It is a high-speed USB data-path switch/multiplexer used to route USB signals between a host controller and downstream USB ports (commonly in hubs, docking stations, or USB-C implementations). The device provides controlled data-paths with low on-resistance, protection features, and a straightforward control interface to select which port is active. The CXUAEX suffix encodes packaging, temperature range, and handling/options (e.g., lead-free, reel) per the manufacturer’s conventions. For exact pinout, electrical specs, timing, and control method, consult the PI5USB30216 datasheet and product page.

I don’t have the exact datasheet here, but typical features of the PI5USB30216CXUAEX family include:
- 16-channel USB 2.0 switch/mux for high-density USB hub/port-expander designs
- Supports full 480 Mb/s data rate on each switched path
- Serial control interface (I2C or SPI) for per-port enable/disable and status
- Per-port overcurrent protection with fault reporting
- Hot-plug detect and device connect/disconnect signaling
- 5V tolerant I/O with compatible core supplies (often 3.3V/5V compatible)
- Low-power operation with standby/partial-power-down modes and fast wake
- ESD protection on USB data lines for robustness
- Package: CXUAEX (compact package suitable for board-level integration)
Note: exact features and electrical specs can vary by revision and packaging. For precise capabilities, please refer to the official datasheet for PI5USB30216CXUAEX.

- Pin count: 16 pins (QFN16 package)
- Function: USB 2.0 data-line 2:1 crosspoint switch/multiplexer (D+ and D−) that selects between two downstream ports for a single upstream USB port.

Manufacturer: Diodes Incorporated (Pericom brand).
Company type: A global fabless semiconductor company that designs and markets analog, mixed-signal, and interface ICs (including USB switches and related connectivity products).

Typical applications for PI5USB30216CXUAEX include:
