CYUSB3031-BZXC

Application Specific Microcontrollers Overview

The CYUSB3031-BZXC is an EZ-USB FX3S SuperSpeed USB controller featuring a 200-MHz ARM926EJ-S core and 512 KB embedded SRAM. It supports USB 3.0 (5 Gbps) and USB 2.0 peripherals with 32 physical endpoints. The device includes a programmable 100-MHz GPIF II interface, two SDIO ports supporting SD/eMMC storage up to 2TB, and built-in RAID capabilities. Operating at 1.2 V for the core and 1.8–3.3 V for I/O, it is housed in a 10 mm × 10 mm, 121-ball BGA package.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm pin compatibility and temperature grade. Ensure the design accounts for independent power domains: 1.2 V for the core and 1.8–3.3 V for I/O interfaces. Confirm that external components meet the absolute maximum ratings for VBUS and VBATT voltages as specified in the electrical characteristics section of the datasheet.

Application Specific Microcontrollers Selection Notes

Select this component when a 512-KB SRAM configuration is required instead of the 256-KB variant. Verify that the application utilizes the 121-ball BGA package footprint. Ensure the system design supports the selectable clock input frequencies of 19.2, 26, 38.4, or 52 MHz. Check if the specific part number variant supports the 16-bit GPIF II data bus width needed for high-throughput applications.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-USB FX3S family, which provides USB 5 Gbps connectivity with integrated storage host controller capabilities. It serves as a bridge between parallel interfaces like GPIF II and the USB protocol stack. The FX3S series is designed for applications requiring high-speed data transfer and local processing, distinguishing it from simpler bridge controllers by its embedded ARM core and substantial on-chip memory.
