CYWB0125AB-BVXI

Controllers Overview

The CYWB0125AB-BVXI is a West Bridge Antioch peripheral mass storage controller manufactured by Infineon Technologies (formerly Cypress Semiconductor). It features the SLIM architecture for simultaneous independent data paths between the processor, USB, and mass storage. The device supports high-speed USB 2.0 at 480 Mbps with an integrated transceiver and smart Serial Interface Engine. It includes 16 programmable endpoints and memory-mapped interfaces to the main processor. The component operates at a 1.8 V core voltage and supports selectable clock input frequencies of 19.2 MHz, 24 MHz, 26 MHz, and 48 MHz. It is housed in a 100-pin VFBGA package measuring 6 × 6 mm.

Controllers Feature Summary

• SLIM architecture enables simultaneous and independent data paths between the processor, USB host, and mass storage devices.
• Integrated full NAND management capabilities including error correction codes (ECC) and wear-leveling protocols.
• Supports multiple mass storage interfaces including MMC, MMC+, SDIO, CE-ATA, and SLC/MLC NAND Flash.
• Turbo-MTP enabled configuration allows for flexible media transfer protocol support.

Controllers Applications

• Cellular Phones
• Portable Media Players
• Personal Digital Assistants
• Digital Cameras
• Portable Video Recorders

Controllers Procurement Notes

Verify that the specific ordering suffix BVXI corresponds to the 100-pin VFBGA package type and Turbo-MTP enabled status as defined in the official documentation. Confirm compatibility with the required 1.8 V core supply and 3.3 V power sequence control requirements before integration into the design.

Controllers Selection Notes

Select this model when simultaneous USB-to-storage and processor-to-storage operations are required without disturbing main processor functions. Ensure the system design accommodates the 100-pin VFBGA footprint and supports the necessary clock frequencies of 19.2 MHz, 24 MHz, 26 MHz, or 48 MHz for proper operation.

Controllers Part Context

This component belongs to the West Bridge Antioch family, designed to enhance processor systems with flexible mass storage support and high-speed USB connectivity. It serves as a bridge between external processors and various storage media, enabling new usage models such as direct PC-to-storage downloads independent of the main processor.

Controllers Replacement Considerations

The CYWB0124AB-BVXI is a similar variant within the same family but lacks Turbo-MTP enablement. Verify functional requirements regarding media transfer protocols before substituting, as the non-Turbo-MTP version may not support all intended firmware configurations.
