Product details

Overview

CYUSB3016-BZXC 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 PHY (5 Gbps), USB 2.0 PHY, and supports USB vendor class protocol for custom data streaming in high-bandwidth imaging and instrumentation applications.

For engineers reviewing the CYUSB3016-BZXC datasheet, CYUSB3016-BZXC pinout, CYUSB3016-BZXC application, or CYUSB3016-BZXC equivalent, key selection criteria include its re-enumeration capability, slave FIFO interface timing at 100 MHz, independent I/O voltage domains (1.2–3.3 V), ultra-low-power core power-down mode (<60 µA), and BGA-121 package compatibility with FPGA/ISP interfacing.

Technical Context

The CYUSB3016-BZXC implements a distributed DMA architecture enabling 375-MBps throughput between its General Configurable Interface and USB interface. Its ARM926EJ-S core runs at 200 MHz and executes firmware loaded via USB re-enumeration - a two-step process where initial enumeration uses Cypress VID (0x04B4), followed by dynamic descriptor/firmware download and electrical disconnect/reconnect.

It supports three physical USB endpoints, configurable clock inputs (19.2/26/38.4/52 MHz), and dual power domains: 1.2-V core and scalable I/O (1.2–3.3 V for SPI/I²C). The device lacks UVC/UAC support - distinguishing it from CYUSB3017 - and targets vendor-class data acquisition rather than standardized video/audio streaming.

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
CYUSB3015-BZXC	Identical architecture and pinout; differs only in factory-programmed configuration fuse - supports same vendor-class functionality as CYUSB3016.	No functional distinction in USB vendor class operation; both lack UVC/UAC firmware support present in CYUSB3017.	Select based on availability and qualification history; CYUSB3015 has longer production track record in data-acquisition modules.
CYUSB3017-BZXCT	Includes preloaded UVC/UAC firmware and extended descriptor tables; adds HDMI receiver interface support and audio path (I²S).	Targeted for plug-and-play webcams and audio/video peripherals; not suitable for custom vendor-class protocols requiring full firmware control.	Choose CYUSB3017 only when USB Video Class compliance and zero-driver deployment are mandatory - not for proprietary data pipelines.

Compared with CYUSB3016-BZXC, CYUSB3015-BZXC offers identical performance and interface flexibility with marginally broader legacy design adoption, while CYUSB3017-BZXCT trades configurability for standardized UVC/UAC compliance - making CYUSB3016 optimal for custom high-throughput vendor-class systems requiring full firmware control and minimal driver dependencies.

CYUSB3016-BZXC accepts external clock inputs at 19.2, 26, 38.4, or 52 MHz via dedicated CLK pins. A 19.2-MHz crystal is explicitly validated for low-jitter operation in synchronous sensor interfaces, and the PCLK output can be derived from these sources with programmable dividers.

Can CYUSB3016-BZXC boot directly from SPI flash without host intervention?

Yes. The device supports SPI boot mode where it loads firmware, descriptors, and optional FPGA configuration from an external SPI flash upon power-up - enabling fully autonomous operation without USB host involvement or re-enumeration sequence.

Is the 121-ball BGA package RoHS-compliant and lead-free?

Yes. The CYUSB3016-BZXC package is specified as Pb-free with matte tin finish on solder balls, compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) handling requirements.
