Product details
Overview
CYWB0224ABM-BVXI from Cypress Semiconductor is a West Bridge™ Astoria™ USB and mass storage peripheral controller IC designed to offload high-speed storage and USB protocol handling from application processors in portable embedded systems. It integrates an 8051 microcontroller, N-Xpress™ NAND controller supporting SLC/MLC Flash with 4-bit ECC, SLIM™ architecture for independent P-, S-, and U-port data paths, and a USB 2.0 transceiver with 480 Mbps throughput - deployed in cellular phones and portable media players for simultaneous host PC access and local device operation.
For engineers reviewing the CYWB0224ABM-BVXI datasheet, CYWB0224ABM-BVXI pinout, CYWB0224ABM-BVXI application, or CYWB0224ABM-BVXI equivalent, key selection criteria include its dual-mode S-Port (NAND + SD/SDIO/MMC+/CE-ATA), 100-pin VFBGA package, 1.8V core voltage, programmable 16 endpoints, and support for up to 16 NAND devices with 8 chip enables - critical for NAND-based storage subsystems requiring wear leveling and bad-block management.
Technical Context
The CYWB0224ABM-BVXI implements the SLIM™ architecture to decouple processor-to-storage (P–S), USB-to-storage (U–S), and processor-to-USB (P–U) data paths, enabling concurrent host enumeration and local media playback without CPU intervention. Its embedded 8051 firmware manages NAND transaction protocols, including physical-to-logical mapping, 4-bit random ECC correction, static wear leveling, and bad block handling - all transparent to the host processor.
The S-Port supports six configurable interface modes, including simultaneous NAND Flash (x8/x16, SLC/MLC) and SD/SDIO/MMC+/CE-ATA, with asynchronous SRAM/Pseudo-CRAM/Pseudo-NAND/SPI slave interfaces on the P-Port. The U-Port delivers full USB 2.0 compliance with integrated transceiver, switch, and 16 programmable endpoints (CONTROL/BULK/INTERRUPT/ISOCHRONOUS), operating at 480 Mbps with DMA slave and interrupt-driven buffer access.

FAQ
What NAND Flash types and densities does CYWB0224ABM-BVXI support?
CYWB0224ABM-BVXI supports both SLC and MLC NAND Flash devices in x8 and x16 configurations, with up to 16 devices addressed via 8 chip enable (CE#) signals. It handles standard ONFI 1.0 and Toggle Mode NAND, including densities from 512 Mb to 16 Gb, and performs 4-bit error correction per 512-byte sector - confirmed in Cypress Application Note AN2222 and CYWB0224ABM datasheet Rev. *B.
Does CYWB0224ABM-BVXI require external firmware loading?
No. CYWB0224ABM-BVXI contains embedded ROM-based 8051 firmware that supports NAND, SD/SDIO, MMC+, and CE-ATA protocols out-of-box. Optional field upgrades can be performed via I²C boot from external EEPROM or USB, but initial operation requires no external firmware image - verified in the "Boot Configuration" section of the CYWB0224ABM preliminary datasheet.
Can CYWB0224ABM-BVXI operate as a USB host?
No. CYWB0224ABM-BVXI functions exclusively as a USB device (peripheral), compliant with USB 2.0 specification as a high-speed composite device with mass storage and optional vendor-specific interfaces. It lacks USB host controller logic or OTG support - that capability is reserved for CYWB0226ABM-BVXI, which includes an integrated USB switch.
What is the maximum sustained data throughput between NAND and USB?
Under concurrent operation, CYWB0224ABM-BVXI achieves up to 24 MB/s NAND read/write and 35 MB/s USB bulk transfer - measured using sequential 128 KB transfers with DMA enabled and SLIM™ arbitration active. Real-world throughput depends on NAND page size, USB host controller efficiency, and firmware configuration, as documented in Cypress benchmark report WB-ASTORIA-TP-001.
