Product details
Overview
CYWB0226ABM-BVXIT from Cypress Semiconductor is a West Bridge™ Astoria™ USB and mass storage peripheral controller IC with integrated USB 2.0 transceiver, SLIM™ architecture, and N-Xpress™ NAND controller supporting SLC/MLC NAND Flash (up to 16 devices via 8 CE#), SD/SDIO/MMC+/CE-ATA interfaces, and 4-bit ECC. It operates at 1.8 V core voltage, supports 19.2–48 MHz clock inputs, and is packaged in a 6×6 mm 100-pin VFBGA for portable media players and cellular handsets.
For engineers reviewing the CYWB0226ABM-BVXIT datasheet, CYWB0226ABM-BVXIT pinout, CYWB0226ABM-BVXIT application, or CYWB0226ABM-BVXIT equivalent, key selection criteria include simultaneous P-port/S-port/U-port data paths, NAND+SD coexistence capability, USB 2.0 high-speed (480 Mbps) compliance, 16 programmable endpoints, and support for pseudo CRAM/SRAM/NAND/SPI processor interfaces.
Technical Context
The CYWB0226ABM-BVXIT implements Cypress's SLIM™ architecture, enabling independent, concurrent data transfers between processor (P-port), mass storage (S-port), and USB (U-port) - e.g., host PC file access while device main CPU remains fully functional. Its embedded 8051 microcontroller manages transaction control but resides outside the data path to preserve throughput.
It integrates an N-Xpress™ NAND controller supporting up to 16 x8/x16 SLC or MLC NAND devices with 4-bit ECC, static wear leveling, and bad block management. The S-port is configurable across six modes including NAND-only, dual SD/SDIO, NAND+SD, and GPIO-only, all controlled by on-chip firmware without requiring external logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-to-mass-storage bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYWB0226ABS-BVXIT | Same package and pinout; supports SLC NAND only (no MLC), no USB switch | Limited to cost-sensitive SLC-only designs without external PHY switching needs | Select when MLC NAND and USB switch functionality are unnecessary to reduce BOM cost |
| CYWB0224ABM-BVXIT | Same NAND/SD features but lacks integrated USB switch and U-port switch control logic | Requires external USB switch IC for multi-PHY configurations; lower integration level | Choose if board layout already includes discrete USB switch and MLC NAND is required without switch overhead |
Compared with CYWB0226ABS-BVXIT and CYWB0224ABM-BVXIT, the CYWB0226ABM-BVXIT uniquely combines MLC NAND support, full USB 2.0 transceiver, and integrated USB switch - enabling single-chip USB host connectivity to dual-storage domains without external switching logic or firmware workarounds.

FAQ
What is the function of the SLIM™ architecture in CYWB0226ABM-BVXIT?
The SLIM™ architecture enables three independent data paths - processor-to-USB, USB-to-storage, and processor-to-storage - to operate concurrently without contention. This allows a host PC to access NAND/SD storage via USB while the main application processor continues executing real-time tasks like telephony or video decode, verified in production handset implementations.
Does CYWB0226ABM-BVXIT require external firmware loading?
No. The embedded 8051 microcontroller executes factory-programmed firmware that supports all NAND, SD/SDIO, MMC+, and CE-ATA protocols. Boot is handled via I²C or processor interface; no external code storage or runtime firmware download is needed for standard operation.
Can CYWB0226ABM-BVXIT interface both NAND Flash and SD cards simultaneously?
Yes. In NAND+SD/SDIO configuration mode, the S-port supports one SD/SDIO/MMC+/CE-ATA interface alongside up to eight NAND chip enables (CE#). This dual-interface capability is hardware-verified and enabled by dedicated buffer allocation per port in the SLIM™ architecture.
What clock frequencies does CYWB0226ABM-BVXIT support?
The device accepts 19.2 MHz, 24 MHz, 26 MHz, or 48 MHz crystal or external clock input via XTALIN. All frequencies are supported across all operating modes and have been validated for USB 2.0 high-speed timing compliance and NAND/SD interface setup/hold margins.
