Product details

Overview

CYUSB3016-BZXCT from Infineon Technologies (formerly Cypress Semiconductor) is a configurable SuperSpeed USB 3.2 Gen 1 peripheral controller with ARM926EJ-S CPU, 512-KB on-chip SRAM, and General Configurable Interface supporting up to 100 MHz and 32-bit parallel bus. It integrates USB 3.2 Gen 1 + USB 2.0 PHYs, supports UVC/UAC/vendor-class protocols, and targets high-bandwidth video/data acquisition systems requiring flexible host-to-FPGA/ISP/sensor bridging.

For engineers reviewing the CYUSB3016-BZXCT datasheet, CYUSB3016-BZXCT pinout, CYUSB3016-BZXCT application, or CYUSB3016-BZXCT equivalent, key selection criteria include USB 3.2 Gen 1 throughput (375 MBps), slave FIFO interface timing at 100 MHz, dual power domains (1.2 V core / 1.8–3.3 V I/O), ultra-low-power core-down mode (<60 µA), and SPI/I²C peripheral support for FPGA configuration and sensor control.

Technical Context

The CYUSB3016-BZXCT implements a tightly coupled ARM926EJ-S microprocessor with integrated USB 3.2 Gen 1 PHY and distributed DMA controller, enabling direct memory-mapped transfers between external peripherals and USB endpoints without CPU intervention. Its General Configurable Interface operates in Slave FIFO mode with programmable data width (8/16/24/32-bit) and clock domain isolation.

It supports re-enumeration via firmware download over USB, allowing dynamic device identity switching (e.g., vendor-class to UVC) without hardware change. Clocking is flexible: selectable crystal inputs (19.2/26/38.4/52 MHz) feed internal PLLs to generate required USB and interface clocks, with independent voltage regulation for core (1.2 V) and I/O banks (1.8–3.3 V).

Key Specifications

Parameter	Value and Actual Design Meaning
USB Compliance	USB 3.2 Gen 1 (5 Gbps) + USB 2.0 backward compatible; enables full-speed, high-speed, and super-speed enumeration.
CPU Core	ARM926EJ-S @ 200 MHz; executes application firmware, handles descriptor management, and controls GPIO/I²C/SPI peripherals.
On-chip Memory	512-KB SRAM; stores boot code, application firmware, DMA buffers, and UVC descriptor tables without external RAM.
Configurable Interface	Slave FIFO mode up to 100 MHz with 8/16/24/32-bit bus; directly interfaces FPGA, image sensor, or HDMI receiver with cycle-accurate timing control.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYUSB3015-BZXCT	Same package and core architecture; lacks UVC/UAC firmware support - vendor-class only.	Restricted to custom driver development; unsuitable for plug-and-play video class deployment.	Select when application requires proprietary protocol and maximum firmware flexibility without UVC overhead.
CYUSB3017-BZXCT	Includes factory-programmed UVC/UAC descriptors and optimized firmware stack; identical pinout and electrical specs.	Pre-configured for USB video/audio class compliance; reduces host driver dependency and certification effort.	Select for UVC/UAC-based products targeting consumer OS compatibility without custom descriptor development.

Compared with CYUSB3016-BZXCT, CYUSB3015-BZXCT offers greater firmware customization but no built-in UVC support, while CYUSB3017-BZXCT provides out-of-box UVC/UAC compliance at the cost of reduced descriptor programmability - all share identical hardware, timing, and power characteristics.

FAQ

What is the primary function of CYUSB3016-BZXCT in a USB video system?

CYUSB3016-BZXCT acts as a configurable USB 3.2 Gen 1 peripheral controller that bridges parallel video data (e.g., from FPGA or image sensor) to a USB host. It handles USB descriptor management, DMA-controlled data transfer, and timing synchronization - enabling UVC-compliant video streaming when paired with appropriate firmware and configuration.

Does CYUSB3016-BZXCT require external memory to operate?

No. CYUSB3016-BZXCT integrates 512 KB of on-chip SRAM, sufficient to store boot firmware, application code, USB descriptors, and DMA buffers. External memory is optional and used only for extended frame buffering or large FPGA configuration images stored in SPI flash.

Can CYUSB3016-BZXCT support both USB 2.0 and USB 3.2 Gen 1 simultaneously?

Yes. The device integrates dual USB PHYs and supports concurrent USB 2.0 (D+/D−) and USB 3.2 Gen 1 (SSTX/SSRX) operation. It automatically negotiates the highest supported speed during enumeration and maintains backward compatibility without hardware modification.

How does the re-enumeration feature benefit system design?

Re-enumeration allows CYUSB3016-BZXCT to first appear as a generic Cypress device for firmware download, then disconnect and reconnect as a fully customized USB device (e.g., UVC camera or vendor-class instrument). This eliminates the need for separate programming hardware and enables field-upgradable device identities and descriptors.
