EZ-USB™ FX3S USB 5 Gbps Peripheral Controller with Storage Interface

Infineon EZ-USB™ FX3S is the latest member of the highly successful EZ-USB™ FX3 family of USB 5 Gbps peripheral controllers. In addition to USB functionality and a powerful Arm® Cortex®, EZ-USB™ FX3S’s integrated storage host controllers enable developers to add support for SD/eMMC memories and SDIO devices to their systems.

Based on the proven EZ-USB™ FX3 platform, EZ-USB™ FX3S leverages EZ-USB™ FX3’s familiar ecosystem and package to reduce your time-to-market and design complexity. EZ-USB™ FX3S has the fully configurable general programmable interface (GPIF II), which can interface with virtually any processor, ASIC, image sensor or FPGA with a parallel port. It provides easy and glue-less connectivity to popular industry interfaces such as synchronous slave FIFO, asynchronous SRAM, asynchronous and synchronous address data multiplexed interfaces, and CompactFlash. Additionally, users can define their own custom master and slave interfaces using Infineon's GPIF II (general programmable interface) designer tool.

EZ-USB™ FX3S supports up to 2 storage ports allowing developers to greatly expand their system capabilities. It supports SD 3.0 (UHS-I), eMMC 4.41 and SDIO 3.0 standards. It gives you full flexibility in terms of simultaneous data paths (between U-Port & S-Port, between P-Port & S-Port, between U-Port & P-Port), and it also allows the system to do data storage and data transfer at the same time.

FX3S can support up to 2 TB SDXC cards giving tremendous data capacity. By using 2 eMMC devices in parallel, developers can theoretically support up to 208 MBps of data storage bandwidth. Using SDIO 3.0, developers can greatly expand their system capabilities to support features such as Wi-Fi, GPS, LTE, etc.
