CYUSB3011-BZXC

CYUSB3011-BZXC is a Cypress EZ-USB USB device controller IC. It is designed to implement USB peripheral functionality in embedded systems without needing an external host controller. The device typically includes a USB transceiver, an on‑chip microcontroller (8051-compatible) with RAM, and a firmware interface, allowing custom USB data handling via Cypress firmware/API. It supports USB 2.0 operations (full-speed/high-speed as configured) and provides multiple endpoints and I/O options for integrating USB into your design. The BZXC suffix denotes a specific RoHS‑compliant package variant. Development uses Cypress EZ-USB tools and SDKs to create custom USB functions (no external MCU required for USB processing). For exact electrical specs, pinout, timing, power, and toolchain details, consult the CYUSB3011-BZXC datasheet, reference designs, and application notes.

Here are the typical features of CYUSB3011-BZXC (EZ-USB family):
- USB 2.0 peripheral controller with Hi-Speed (480 Mbps) capability
- On-chip 8051-compatible microcontroller with internal RAM/ROM for firmware
- Flexible data path: Slave FIFO interface and GPIF II for high-throughput data exchange with external logic (FPGA/ASIC)
- Multiple configurable endpoints with dedicated buffering
- Serial I/O options: I2C, SPI, UART for host/peripheral communication
- General-purpose I/O (GPIOs) for user applications
- USB classes supported via firmware (e.g., HID, Mass Storage, Audio) or custom classes
- Bus-powered or self-powered operation with standard power-management and suspend/resume
- Integrated USB transceiver and support for standard USB signaling
- Development tooling and libraries (EZ-USB API/firmware framework)
Note: exact memory sizes, endpoint counts, and some capabilities can vary by revision; consult the official datasheet for precise specifications.
