CYUSB3011-BZXC

CYUSB3011-BZXC is a Cypress (Infineon) USB hub/controller IC. It is used to add USB hub functionality to an embedded system by providing an upstream USB port to the host and multiple downstream ports for devices. The device includes the hub logic and transceivers/PHYs, and is configured and managed by a host MCU via a register interface (typically I2C or SPI). Key features usually include per-port power switching, over-current protection, suspend/resume support, and USB topology management. Some variants include on‑chip memory; others use external flash for firmware/descriptor storage. The “BZXC” suffix denotes a specific package/temperature grade variant. For exact port counts, electrical specs, and programming requirements, refer to the CYUSB3011 data sheet and reference designs.

Here are the typical features you’d expect for a CYUSB3011-BZXC (Cypress EZ-USB family) device. For exact specs, refer to the official datasheet.
- USB controller: USB 2.0 high-speed capable (480 Mbps) device controller with full-/low-speed compatibility
- On-chip microcontroller for USB function firmware (embedded processor and flash/ROM for firmware)
- On-chip RAM and ROM to store firmware and data
- Flexible endpoint architecture with DMA support for high data throughput
- Multiple I/O interfaces: I2C, SPI, UART, and general-purpose I/O (GPIO)
- Software-configurable USB class support (e.g., HID, Mass Storage, custom classes) via Cypress API
- Power management features and low-power operation options
- RoHS-compliant packaging (BZXC) with suitable package/reliability options
- Development ecosystem: Cypress EZ-USB toolchain and libraries for firmware development
Note: Exact memory sizes, endpoint counts, clock requirements, and peripheral set can vary by revision and package. Please consult the specific datasheet for CYUSB3011-BZXC to confirm the precise features.

It uses a Ball Grid Array (BGA) package.

- Pin count: 68-pin QFN (BZXC package)
- Function: USB 3.0 peripheral/host controller (FX3 family) with an integrated processor and DMA, providing USB 3.0/2.0 PHY and endpoint/controller logic for custom USB device implementations.
