CYWB0124AB-BVXI

Controllers Overview

The CYWB0124AB-BVXI is a West Bridge Antioch USB/Mass Storage Peripheral Controller manufactured by Cypress Semiconductor. It features SLIM architecture for independent data paths between the processor, USB, and mass storage interfaces. The device supports High Speed USB at 480 Mbps with an integrated transceiver and 16 programmable endpoints. Mass storage support includes MMC/MMC+/SD/CE-ATA and SLC NAND flash (×8 or ×16) with full management including ECC and wear leveling. It operates on a 1.8 V core voltage with selectable clock inputs of 19.2, 24, 26, or 48 MHz. The component is housed in a 6 × 6 mm VF BGA package.

Controllers Feature Summary

• SLIM architecture enables simultaneous and independent data paths between the processor, USB, and mass storage interfaces without disturbing device functions.
• Integrated 8051 microprocessor manages transaction flow and performs NAND flash management tasks such as ECC correction and wear leveling.
• Supports Microsoft Media Transfer Protocol (MTP) with optimized data throughput via Turbo-MTP implementation.
• Flexible I/O ports operate between 1.8 V and 3.3 V with adjustable slew rate and drive strength.

Controllers Applications

• Cellular phones
• Portable media players
• Personal digital assistants
• Digital cameras
• Portable video recorders

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature range. Ensure compatibility with system power domains, particularly the 1.8 V core and 3.3 V USB I/O supplies. Confirm clock configuration requirements for XTALIN and XVDDQ levels before integration.

Controllers Selection Notes

Select this controller for applications requiring high-speed USB 2.0 connectivity alongside direct mass storage access. Consider the SLIM architecture if simultaneous PC synchronization and local processor access are required. Verify that the target mass storage devices, such as SLC NAND or SD cards, are supported by the embedded firmware capabilities.

Controllers Part Context

The CYWB0124AB belongs to the West Bridge Antioch family of USB/Mass Storage Peripheral Controllers. This series is designed to offload USB protocol processing from the main application processor, allowing for efficient data transfer and reduced CPU load in mobile and portable electronic devices.
