CYWB0224ABMX-FDXIT

Controllers Overview

The CYWB0224ABMX-FDXIT is a West Bridge Astoria USB and Mass Storage Peripheral Controller manufactured by Infineon Technologies. It features an integrated N-Xpress NAND controller capable of interleaving up to 16 NANDs with 8 chip enables for x8 or x16 SLC/MLC devices. The device supports High Speed USB at 480 Mbps compliant with USB 2.0 specifications, utilizing a SLIM architecture for simultaneous independent data paths between the processor and USB ports. It includes a flexible processor interface supporting multiplexing/nonmultiplexing address/data buses, SRAM, pseudo CRAM, pseudo NAND, and SPI slave modes. Key functional parameters include a 1.8V core voltage operation, 16 programmable endpoints, and selectable clock input frequencies of 19.2 MHz, 24 MHz, 26 MHz, and 48 MHz.

Controllers Feature Summary

• SLIM architecture enabling simultaneous and independent data paths between the processor and USB interfaces without disturbing device functions.
• Integrated N-Xpress NAND controller technology managing bad block handling, static wear leveling, and 4-bit error correction coding for MLC devices.
• Flexible processor interface supporting multiple modes including multiplexed/nonmultiplexed address/data buses, SRAM, pseudo CRAM, pseudo NAND, and SPI slave.
• High-speed USB 2.0 compliance with an integrated transceiver and switch, supporting up to 480 Mbps transfer rates.

Controllers Applications

• Cellular Phones
• Portable Media Players
• Personal Digital Assistants
• Portable Navigation Devices
• Digital Cameras

Controllers Procurement Notes

Verify the specific suffix 'FDXIT' against official Infineon documentation to confirm packaging details such as tape and reel configuration or moisture sensitivity level. Ensure the component matches the original Cypress Semiconductor design specifications now managed by Infineon. Confirm RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer before placing orders.

Controllers Selection Notes

Select this controller when designing systems requiring simultaneous USB host/device functionality and mass storage management via NAND Flash or SD/MMC interfaces. Choose the ABM variant over ABS if MLC NAND Flash support is required, as ABS supports only SLC. Ensure the system design accommodates the 1.8V core voltage requirement and provides the necessary clock inputs (19.2, 24, 26, or 48 MHz) for proper operation.

Controllers Part Context

This component belongs to the West Bridge Astoria family, originally developed by Cypress Semiconductor Corporation before its acquisition by Infineon Technologies. The Astoria series is designed to offload complex USB and mass storage protocols from the main application processor, reducing CPU load and power consumption in portable electronic devices.

Controllers Replacement Considerations

Direct replacements within the same package and pinout include other variants from the Astoria family such as CYWB0224ABS-BVXI or CYWB0226ABM-BVXI, depending on whether SLC-only or MLC support and USB switch integration are needed. Verify firmware compatibility and electrical characteristics before substituting.
