CYUSB3016-BZXI

Application Specific Microcontrollers Overview

The CYUSB3016-BZXI is a configurable SuperSpeed USB controller from the EZ-USB SX3 family. It integrates a 200-MHz ARM926EJ-S core with 512 KB of embedded SRAM and supports USB 3.2 Gen 1 (5 Gbps) and USB 2.0 peripherals. The device features three physical endpoints and a General Configurable Interface supporting up to 100 MHz operation with 8-, 16-, 24-, or 32-bit data buses. It operates on independent power domains, including a 1.2 V core and I/Os ranging from 1.2 V to 3.3 V. The component is housed in a 121-ball, 10 mm × 10 mm, 0.8 mm pitch Pb-free BGA package.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage levels and package variants. Confirm that the design utilizes the EZ-USB SX3 Configuration Utility for firmware and descriptor setup. Ensure external components meet the specified electrical characteristics for clocking and power domains.

Application Specific Microcontrollers Selection Notes

Select this model when a USB vendor class interface is required, as opposed to the UVC/UAC capabilities found in the CYUSB3017 variant. Ensure the application requires a 32-bit data bus width if utilizing the full General Configurable Interface bandwidth. Verify that the system can support the necessary SPI flash configuration storage and that the ARM926EJ-S core resources are sufficient for the intended firmware complexity.

Application Specific Microcontrollers Part Context

The CYUSB3016 is part of the EZ-USB SX3 family, which also includes the CYUSB3015 and CYUSB3017. While all share the same core architecture and package, the CYUSB3016 is specifically designated for USB vendor class applications. This distinguishes it from the CYUSB3017, which adds support for USB Video Class (UVC) and USB Audio Class (UAC).

Application Specific Microcontrollers Replacement Considerations

The CYUSB3015 serves as a functional alternative within the same package if a narrower data bus is acceptable. The CYUSB3017 provides similar hardware but includes additional protocol support for UVC and UAC classes.
