Description

PI3USB31532ZLEX is a high-speed USB data-path switch/multiplexer from Pericom (now Renesas). It is used to route USB differential data lines in connectivity solutions such as USB hubs, docking stations, and Type-C dual-role/alternate-mode implementations. The device supports USB 2.0 and USB 3.x data rates, offers configurable path selection via a control input, and includes protections suitable for high-speed USB interfaces (e.g., ESD). The ZLEX suffix indicates a RoHS-compliant, lead-free variant in a specific package. Typical applications include USB hubs, USB docking stations, and USB Type-C port controllers where flexible, low-loss switching of USB data paths is required. For exact features, pinout, supply ranges, timing, and package details, refer to the PI3USB31532ZLEX datasheet. If you’d like, I can summarize the key electrical specs and recommended use-cases from the datasheet.

Equivalent

Direct equivalents (3:1 USB 3.0 data switch) include:
- FSA31532 (Fairchild/ON Semiconductor)
- NX3L3152 (NXP)
Other vendors offer similar 3:1 USB switches (e.g., TI’s TS3USB3152/3153 family). Always verify pinout, package, and electrical specs before substituting.

Features

Here are the likely features of PI3USB31532ZLEX (USB 3.0 crosspoint switch/mux):
- 3-port USB 3.0 switch: one upstream and two downstream ports (USB 3.0 SuperSpeed)
- 5 Gbps data-rate support
- Crosspoint/mux functionality to route USB 3.0 signals between ports
- Control via I2C/SMBus (configurable operation)
- Hot-plug support with protection features
- ESD protection on USB data lines
- Low-power operation and suitable for small, RoHS-compliant packages (ZLEX variant)
- General purpose, used for USB port sharing, docking stations, or front-panel switching
Note: exact electrical specs (voltages, timing, temperature range, I/O levels) can vary by revision; please consult the official datasheet for precise details.

Pinout

- Pin count: 16 pins (16-pin package, e.g., QFN).
- Function: USB 3.0/2.0 3:1 crosspoint switch (data-path multiplexer) that selects one of up to three upstream ports to connect to a downstream port; uses control pins (SEL/OE) to choose which port is active.

Manufacturer

- Manufacturer: Renesas Electronics Corporation (the PI3USB31532 lineage originated with Pericom Semiconductor; Renesas acquired Pericom).
- Company type: A Japanese multinational semiconductor company that designs and manufactures integrated circuits and related products for automotive, industrial, consumer, and communications markets.

Package

It’s in a 20‑pin QFN package (3 mm × 3 mm) with an exposed pad (EP).
