CYWB0124AB-BVXIT

Controllers Overview

The CYWB0124AB-BVXIT is a USB/Mass Storage Peripheral Controller from Cypress Semiconductor's West Bridge Antioch family. It features the 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. It manages NAND flash (SLC) and SD/MMC/CE-ATA devices, including ECC and wear leveling via an embedded 8051 MCU. Key electrical parameters include a 1.8 V core voltage (VDD), 3.3 V USB I/O supply (UVDDQ), and selectable clock inputs of 19.2, 24, 26, or 48 MHz. It operates within a temperature range of -40°C to +85°C and is available in a 6x6 mm VF BGA package.

Controllers Feature Summary

• SLIM architecture enables simultaneous, independent data transfers between the host processor, USB interface, and mass storage devices without disturbing main processor functions.
• Integrated 8051 microprocessor handles firmware execution for NAND management, including physical-to-logical mapping, ECC correction, and wear leveling, while optimizing the high-speed data path.
• Supports Microsoft Media Transfer Protocol (MTP) with Turbo-MTP technology, allowing direct data payload writing to mass storage to bypass the main processor for improved throughput.
• Flexible I/O configuration allows operation at 1.8 V, 2.5 V, or 3.3 V levels with adjustable slew rates and drive strengths for P-port, S-port, and USB interfaces.

Controllers Applications

• Cellular phones
• Portable media players
• Digital cameras

Controllers Procurement Notes

Verify the specific ordering suffix BVXIT against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required clock frequency selection pins (XTALSLC) and power domain sequencing requirements during integration. Confirm that the target application utilizes the appropriate mass storage interface configuration (SD/MMC vs. NAND) supported by this variant.

Controllers Selection Notes

Select this controller when designing systems requiring simultaneous USB connectivity and local mass storage access without burdening the main application processor. Choose this model over the CYWB0125AB if the specific pinout or internal configuration differences documented in the datasheet align with the board layout constraints. Ensure the design supports the necessary 1.8 V core and 3.3 V USB I/O power domains.

Controllers Part Context

The CYWB0124AB belongs to the West Bridge Antioch series of USB peripheral controllers designed for mobile and portable electronics. It complements Cypress's broader portfolio of connectivity solutions by providing specialized hardware offloading for USB Mass Storage Class operations. This component bridges the gap between high-speed USB hosts and various non-volatile memory technologies commonly found in consumer devices.
