Product details

Overview

CYUSB3011-BZXC from Infineon is a USB 3.2 Gen 1 (5 Gbps) and USB 2.0 programmable SuperSpeed USB controller with ARM926EJ-S core (200 MHz), 512 KB SRAM, 32 physical endpoints, and GPIF II interface supporting 8-/16-/24-/32-bit buses up to 100 MHz - used in high-bandwidth video capture cards, industrial cameras, and medical imaging devices.

For engineers reviewing the CYUSB3011-BZXC datasheet, CYUSB3011-BZXC pinout, CYUSB3011-BZXC application, or CYUSB3011-BZXC equivalent, key selection criteria include USB 3.2 Gen 1 PHY compliance (TID #340800007), configurable GPIF II timing, dual-power-domain operation (1.2 V core / 1.8–3.3 V I/O), and boot flexibility via SPI/I²C/USB.

Technical Context

The CYUSB3011-BZXC integrates a full-featured USB 3.2 Gen 1 transceiver with integrated 5-Gbps PHY and USB 2.0 HS PHY, enabling simultaneous SuperSpeed and High-Speed device/host operation. It supports OTG Supplement v2.0 with HS-OTG host/peripheral mode and renumerability.

GPIF II provides deterministic, software-configurable parallel interface logic with up to 16 control signals and support for synchronous/asynchronous Slave FIFO, SRAM, and custom state machines - enabling direct connection to FPGAs, image sensors, and ADCs without external glue logic.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB 3.2 Gen 1 controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYUSB3014-BZXI	Same architecture but 256 KB SRAM and -40°C to +85°C industrial temp grade; identical pinout and firmware compatibility.	Preferred for extended temperature environments (e.g., outdoor surveillance, factory floor test equipment).	Select when operating ambient exceeds 70°C or long-term reliability under thermal cycling is critical.
CX3-EBZ	Dedicated MIPI CSI-2 to USB 3.0 bridge; no ARM core or general-purpose GPIF II; fixed-function silicon.	Optimized for mobile image sensors only; lacks programmability for non-CameraLink/FPGA use cases.	Choose only for cost-sensitive, single-sensor camera designs where firmware customization is unnecessary.

Compared with CYUSB3014-BZXI, CYUSB3011-BZXC offers higher on-chip memory for complex UVC descriptors and multi-stream buffering; versus CX3-EBZ, it provides full firmware control and interface flexibility at the cost of higher development effort.

FAQ

Does CYUSB3011-BZXC support USB 3.2 Gen 2 (10 Gbps)?

No. CYUSB3011-BZXC implements USB 3.2 Gen 1 (5 Gbps) only, as confirmed by its PHY compliance with TID #340800007 and maximum link rate of 5 GT/s. It does not support Gen 2 encoding, 10-Gbps signaling, or enhanced SuperSpeedPlus features.

Can the ARM926EJ-S core run bare-metal firmware without ThreadX?

Yes. The SDK supports bare-metal development using GCC toolchain and startup code provided in the FX3 TRM. All peripheral drivers (USB, GPIF II, SPI, I²C) are accessible in source form, enabling deterministic real-time control without RTOS overhead.

What is the minimum supported crystal frequency for CYUSB3011-BZXC?

The minimum supported crystal input is 19.2 MHz, as specified in Section 10 "Clocking" of the datasheet. This frequency enables stable PLL lock for both USB 3.2 Gen 1 (125-MHz reference) and USB 2.0 (48-MHz reference) operation.

Is CYUSB3011-BZXC pin-compatible with CYUSB3014-BZXI?

Yes. Both share identical 121-ball BGA package (10 mm × 10 mm, 0.8-mm pitch) and pin-for-pin signal mapping per Infineon's FX3 variant table. Firmware and hardware designs are interchangeable except for SRAM size and temperature grade.
