EZ-USB® SD3 | Cypress Semiconductor



Cypress's EZ-USB SD3 is a SuperSpeed USB 3.0 to storage controller that lets developers add storage to any USB port. SD3 supports up to two independent storage ports which may be configured in any combination of SD, eMMC or SDIO. The storage standards supported are SD3.0, eMMC4.41 and SDIO3.0 In addition SD3 comes with built-in RAID with support for RAID0 and RAID1. With RAID support SD3 can be a low power, small footprint RAID-on-Chip (ROC) controller with SD or eMMC storage.


In addition to the storage ports SD3 comes with an ARM9 CPU and 512KB SRAM providing over 200 MIPS of computational power. SD3 has plenty of GPIOs and support for multiple peripheral interfaces such as I2C, SPI, UART and I2S. SD3 is available in a 121 ball BGA and 131 ball WLCSP package.
