Infineon Technologies CYUSB3015-BZXI

Overview

CYUSB3015-BZXI 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, 32-bit parallel bus, and Slave FIFO mode. It implements USB vendor class protocol, supports SPI boot flash and I²C peripherals, and targets high-bandwidth data acquisition and video bridging applications.

For engineers reviewing the CYUSB3015-BZXI datasheet, CYUSB3015-BZXI pinout, CYUSB3015-BZXI application, or CYUSB3015-BZXI 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, and re-enumeration-capable firmware loading over USB.

Technical Context

The CYUSB3015-BZXI integrates a 200-MHz ARM926EJ-S CPU with tightly coupled memory (ITCM/DTCM), distributed DMA controller, and dual-protocol USB PHY supporting simultaneous SuperSpeed (5 Gbps), High-Speed (480 Mbps), and Full-Speed (12 Mbps) operation. Its General Configurable Interface operates at up to 100 MHz with programmable bus width (8/16/24/32-bit) and timing modes for FPGA, image sensor, or ASIC interfacing.

Power architecture includes independent core (1.2 V) and I/O (1.8–3.3 V) domains, ultra-low-power core power-down mode (<60 µA with VBATT on), and support for multiple clock inputs (19.2/26/38.4/52 MHz). Boot sources include SPI flash and USB re-enumeration with descriptor download.

FAQ

Does CYUSB3015-BZXI support USB Video Class (UVC) natively?

No. CYUSB3015-BZXI is the vendor-class variant of the SX3 family and does not include built-in UVC firmware or descriptors. It requires custom firmware development for video streaming. The CYUSB3017-BZXI variant provides native UVC/UAC support with preconfigured video pipeline logic.

What clock sources are supported for the General Configurable Interface?

The CYUSB3015-BZXI accepts external clock inputs up to 100 MHz on the CLK pin, synchronized to the internal PLL. It also supports crystal inputs at 19.2 MHz, 26 MHz, 38.4 MHz, or 52 MHz for system clock generation, with internal dividers enabling precise interface timing alignment.

Can CYUSB3015-BZXI operate without external SPI flash memory?

Yes. While SPI flash is the primary boot source, CYUSB3015-BZXI supports USB re-enumeration mode: it boots from internal ROM, enumerates as a Cypress device, downloads firmware and descriptors over USB, then reboots into the configured application-enabling flashless prototyping and field updates.

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

Yes. The CYUSB3015-BZXI uses a Pb-free, RoHS-compliant 121-ball BGA package with 0.8-mm pitch and 10 mm × 10 mm footprint. It meets JEDEC J-STD-020 moisture sensitivity level 3 and is qualified for industrial temperature range (–40°C to +85°C).
