CYUSB3015-BZXCT

Application Specific Microcontrollers Overview

The Infineon Technologies CYUSB3015-BZXCT is a configurable SuperSpeed USB peripheral controller belonging to the EZ-USB SX3 family. It integrates a 32-bit ARM926EJ-S microprocessor operating at 200 MHz and 512 KB of embedded SRAM. The device supports USB 3.2 Gen 1 and USB 2.0 protocols with a 5-Gbps physical layer. It features a General Configurable Interface supporting up to 100 MHz operation with 8-, 16-, 24-, or 32-bit data buses. The component operates on independent power domains, including a 1.2 V core supply and I/O supplies ranging from 1.8 V to 3.3 V.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'BZXCT' against official ordering information to confirm package type and temperature grade. Confirm availability status as distribution channels may list end-of-life notifications or limited stock for this specific variant.

Application Specific Microcontrollers Selection Notes

Select the CYUSB3015 variant specifically for USB vendor class applications requiring custom descriptors. Ensure the design accommodates the 121-ball BGA package dimensions and provides adequate thermal dissipation for the 1.2 V core domain.

Application Specific Microcontrollers Part Context

The CYUSB3015 is part of the EZ-USB SX3 series, designed as a configurable alternative to previous FX3 controllers. It shares the same 121-ball BGA footprint but offers distinct configuration options via the SX3 Configuration Utility compared to the UVC-focused CYUSB3017.

Application Specific Microcontrollers Replacement Considerations

The CYUSB3016-BZXCT serves as a functional substitute within the SX3 family, differing primarily in interface width capabilities. Verify pin compatibility and firmware configuration requirements when migrating between these variants.

Application Specific Microcontrollers FAQ

What are the supported clock input frequencies?

The device supports a 19.2-MHz crystal input or external clock inputs of 19.2, 26, 38.4, and 52 MHz.

How does the re-enumeration feature work?

SX3 performs a two-step process where it first enumerates with a Cypress Vendor ID to download firmware and descriptors, then disconnects and reconnects as the configured device.

What is the maximum VBUS voltage tolerance?

The maximum input voltage on the VBUS pin is 6 V; an external overvoltage protection device is required if the charger supplies up to 9 V.
