Product details

Overview

CYUSB3015-BZXIT from Infineon Technologies (formerly Cypress) 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, 32-bit parallel bus, and Slave FIFO mode - deployed in USB vendor-class video capture, data acquisition, and FPGA configuration systems.

For engineers reviewing the CYUSB3015-BZXIT datasheet, CYUSB3015-BZXIT pinout, CYUSB3015-BZXIT application, or CYUSB3015-BZXIT equivalent, key selection criteria include USB 3.2 Gen 1 PHY compliance, 375-MBps DMA throughput, 1.2-V core/1.8–3.3-V I/O voltage domains, ultra-low-power core power-down (<60 µA), and support for SPI boot flash and I²C peripherals at up to 1 MHz.

Technical Context

The CYUSB3015-BZXIT implements a dual-mode USB interface compliant with USB 3.2 Gen 1 (5 Gbps) and backward-compatible USB 2.0, using integrated SuperSpeed and High-Speed PHYs. Its ARM926EJ-S CPU runs at 200 MHz and manages distributed DMA transfers between the General Configurable Interface and USB endpoints.

It features three physical USB endpoints, independent power domains (1.2-V core, 1.8–3.3-V I/O), and re-enumeration capability enabling dynamic firmware- and descriptor-based device identity switching - critical for field-upgradable USB vendor-class devices without hardware changes.

Key Specifications

Parameter	Value and Actual Design Meaning
USB Compliance	USB 3.2 Gen 1 (5 Gbps) and USB 2.0; enables high-bandwidth vendor-class data streaming without protocol translation
CPU Core	ARM926EJ-S @ 200 MHz; executes custom firmware, handles descriptor management, and controls DMA engine
On-chip Memory	512-KB SRAM; stores application code, descriptors, DMA buffers, and runtime variables - eliminates external RAM in compact designs
General Interface	Configurable 8/16/24/32-bit parallel bus up to 100 MHz; supports Slave FIFO and image sensor timing for direct FPGA/ASIC interfacing
Power Modes	Core power-down <60 µA (VBATT on); enables battery-backed standby in portable USB devices
Clock Inputs	19.2 / 26 / 38.4 / 52 MHz; allows crystal or oscillator sourcing with 19.2-MHz crystal option for low-jitter USB timing
I/O Voltage Range	VIO1–VIO5: 1.2 V to 3.3 V; supports mixed-voltage system integration with FPGAs, sensors, and legacy logic

Pinout & Package

Package: 121-ball, 10-mm × 10-mm, 0.8-mm pitch Pb-free BGA (package code BZX).

Pin/Terminal	Circuit Role	Design Meaning
SSTX+/SSTX− SSRX+/SSRX−	SuperSpeed differential USB 3.2 transmit/receive pairs	Direct connection to USB 3.2 receptacle; requires controlled 90-Ω differential impedance routing
D+/D−	USB 2.0 High-Speed/Full-Speed differential pair	Backward compatibility path; shared routing with SuperSpeed via multiplexer internal to PHY
GPIF_DATA[31:0]	General Configurable Interface data bus	32-bit bidirectional parallel interface; timing-configurable for Slave FIFO or camera sensor sync
GPIF_ADDR[1:0]	Interface address lines	Selects among four GPIF data transfer modes (e.g., read/write control, status, or command)
CLK, CTL, RDY, FLAGA–FLAGD	Interface control signals	Programmable handshake and status signaling for synchronous/asynchronous peripheral handshaking
VDD, CVDDQ, AVDD, VIO1–VIO5	Power supply domains	Isolated 1.2-V core, 1.8–3.3-V I/O, and analog supplies enable noise-sensitive mixed-signal operation

Key Features

Feature	Design Value
Re-enumeration architecture	Enables single-hardware platform to present multiple USB device identities (e.g., data logger → firmware updater) via dynamic descriptor download
Configurable GPIF interface	Supports custom timing waveforms for non-standard image sensors or ASICs without FPGA glue logic
Distributed DMA controller	Transfers up to 375 MBps from GPIF to USB without CPU intervention - preserves ARM9 bandwidth for application processing
Multi-voltage I/O domains	Allows direct interfacing to 1.8-V FPGAs, 3.3-V sensors, and 1.2-V logic without level shifters
SPI boot flash interface	Loads firmware and configuration on power-up; supports merged FPGA bitstream + SX3 firmware storage in single SPI device

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar configurable USB peripheral controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYUSB3016-BZXIT	Same package and pinout; differs only in factory-programmed USB descriptors and default firmware variant (SX3-Data)	No functional difference; intended for identical vendor-class data applications	Select when requiring identical hardware with preconfigured vendor ID/product ID matching legacy deployments
CYUSB3017-BZXIT	Same silicon; factory-configured for UVC/UAC class support with built-in video descriptor tables and camera controls	Targeted for plug-and-play USB WebCAMs and HDMI capture cards requiring standard UVC enumeration	Choose only if UVC compliance and zero-host-driver deployment are mandatory; not suitable for vendor-class protocols

Compared with CYUSB3016-BZXIT, CYUSB3015-BZXIT offers identical hardware functionality but requires user-provided descriptor configuration via SX3 Utility; versus CYUSB3017-BZXIT, it omits preloaded UVC descriptors, giving full control over USB class definition at the cost of added firmware development effort.

FAQ

What USB classes does CYUSB3015-BZXIT natively support?

CYUSB3015-BZXIT is configured as a USB vendor-class device by default and supports custom class definitions via downloadable descriptors. It does not ship with UVC or UAC firmware preloaded - those require CYUSB3017-BZXIT or user-developed firmware using the SX3 Configuration Utility and ARM9 application code.

Does CYUSB3015-BZXIT require external memory for operation?

No. CYUSB3015-BZXIT contains 512 KB of on-chip SRAM sufficient for firmware execution, descriptor storage, and DMA buffering. External SPI flash is optional and used only for non-volatile firmware and configuration storage - not for runtime code execution.

Can CYUSB3015-BZXIT interface directly with MIPI CSI-2 image sensors?

No. CYUSB3015-BZXIT lacks native MIPI CSI-2 PHY support. It interfaces with parallel-output image sensors (8/16/24/32-bit) or LVDS-to-parallel bridge ICs via its General Configurable Interface. MIPI CSI-2 requires external deserializer or FPGA-based conversion before connecting to GPIF.

What clock sources are supported for USB 3.2 Gen 1 timing compliance?

CYUSB3015-BZXIT supports 19.2 MHz, 26 MHz, 38.4 MHz, and 52 MHz crystal or oscillator inputs. For strict USB 3.2 Gen 1 jitter requirements, a 19.2-MHz fundamental-mode crystal with low phase noise (<1 ps RMS jitter) is recommended and validated in reference designs.
