CYUSB3023-FBXCT

Application Specific Microcontrollers Overview

The CYUSB3023-FBXCT is an EZ-USB SD3 USB and Mass Storage Peripheral Controller supporting USB 3.0 SuperSpeed (5 Gbps) and backward compatibility with USB 2.0. It integrates a 200 MHz ARM926EJ-S processor, 512 KB embedded SRAM, and dual mass-storage ports (S0 and S1). The device supports SD 3.0, eMMC 4.4, and SDIO 3.0 specifications. Key electrical parameters include a core voltage of 1.2 V, I/O voltages ranging from 1.8 V to 3.3 V, and a battery supply of 3.2 V to 6 V. It features thirty-two physical endpoints, an integrated transceiver, and low-power modes consuming less than 60 µA in core power-down.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'FBXCT' against Infineon documentation for package type and tape/reel configuration details. Confirm availability status as distribution channels may list this component as discontinued or limited stock. Ensure compliance with RoHS requirements and moisture sensitivity levels before procurement.

Application Specific Microcontrollers Selection Notes

Select this controller for applications requiring direct USB 3.0 connectivity to SD/eMMC/SDIO storage media. Ensure the design accommodates independent power domains for core (1.2 V) and I/O (1.8–3.3 V). Verify clock source compatibility with supported frequencies (19.2, 26, 38.4, 52 MHz) and check GPIO multiplexing requirements for serial interfaces like SPI, UART, and I2C.

Application Specific Microcontrollers Part Context

The CYUSB3023 belongs to the EZ-USB SD3 family of USB 3.0 mass-storage controllers. It is part of the broader CYUSB30xx series, which includes variants like the FX3 and SX3. This specific model focuses on storage bridge functionality rather than general-purpose GPIF II interfacing found in other series members.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Consult Infineon technical support for cross-reference recommendations if the CYUSB3023-FBXCT is unavailable.
