Infineon Technologies CYUSB3015-BZXCT

Overview

CYUSB3015-BZXCT 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 and 32-bit data bus width. It integrates USB 3.2 Gen 1 + USB 2.0 PHYs, supports USB vendor class protocol, and enables 375-MBps data transfer in USB video or data acquisition systems.

For engineers reviewing the CYUSB3015-BZXCT datasheet, CYUSB3015-BZXCT pinout, CYUSB3015-BZXCT application, or CYUSB3015-BZXCT equivalent, key selection criteria include 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 flash boot capability for field-upgradable firmware.

Technical Context

The CYUSB3015-BZXCT implements a 32-bit ARM926EJ-S CPU running at 200 MHz, coupled with distributed DMA architecture to enable high-throughput streaming between its General Configurable Interface and USB endpoints. Its three physical USB endpoints support vendor-class descriptor configurations without UVC/UAC firmware.

It features independent voltage domains: 1.2-V core supply, 1.8–3.3-V SPI I/O, and 1.2–3.3-V I²C I/O - enabling flexible integration with FPGAs, image sensors, and ADC/DAC peripherals. Clock input options include 19.2, 26, 38.4, or 52 MHz, with 19.2-MHz crystal support for low-jitter timing.

FAQ

What is the maximum sustained data rate achievable with CYUSB3015-BZXCT?

The CYUSB3015-BZXCT supports up to 375 MBps sustained throughput from its General Configurable Interface to USB, verified under Slave FIFO mode with 100-MHz clock and optimal DMA configuration. This rate assumes continuous data flow, minimal host-side latency, and proper endpoint buffer sizing - actual system performance depends on host driver efficiency and USB host controller capabilities.

Does CYUSB3015-BZXCT require external memory for operation?

No. CYUSB3015-BZXCT contains 512 KB of on-chip SRAM sufficient for firmware execution, USB descriptors, DMA buffers, and application variables. External memory is optional and only needed for extended frame buffers (e.g., multi-frame video) or large FPGA configuration bitstreams stored separately from the integrated SPI flash.

Can CYUSB3015-BZXCT be configured to emulate a USB Video Class (UVC) device?

No - CYUSB3015-BZXCT is factory-configured for USB vendor class operation and lacks the built-in UVC firmware stack. The CYUSB3017-BZXCT variant supports UVC/UAC natively. However, custom UVC-compliant firmware can be developed for CYUSB3015 using the SX3 SDK, though it requires full descriptor and protocol implementation by the user.

What clock sources are supported for CYUSB3015-BZXCT operation?

CYUSB3015-BZXCT accepts selectable crystal or oscillator inputs at 19.2 MHz, 26 MHz, 38.4 MHz, or 52 MHz. A 19.2-MHz crystal is recommended for USB-compliant jitter performance. The internal PLL generates all required clocks, including USB 3.2 Gen 1 reference (125 MHz) and CPU clock (200 MHz), with no external clock synthesizer needed.
