SD3.0 / SDIO3.0 / eMMC5.0 Host Controller IP – Advanced Info
The SD3.0/SDIO3.0/eMMC 5.0 Host IP from Arasan Chip Systems is a highly integrated host controller IP solution that supports three key memory card I/O technologies:
- SD3.0
- SDIO3.0
- eMMC5.0
The SD3 / eMMC Host IP handles all of the timing and interface protocol requirements to access these media as well as processing the commands in hardware thereby scaling in both performance and access speeds. The IP supports connection to a single slot and performs multi-block writes and erases that lower access overhead. In addition, a host can utilize this IP to boot directly from an attached eMMC memory, thereby simplifying system initialization during power up. The host interface is based on a standard 32-bit AHB bus which is used to transfer data and configure the SD3 / eMMC5.0 Host IP.
