Special IO – SD/eMMC IO

Overview

SD (Security Digital) and eMMC (embedded MultiMedia Card) IOs are nonvolatile memory interface technology with high bandwidth capabilities, which is particularly developed for flash storage applications. M31 provides a silicon-proven SD/eMMC IO in different process nodes. The SD/eMMC IO complies with interface specifications of SD Association and JEDEC to provide both SDR104 (SD IO) and HS400 (eMMC IO) high-speed modes. The SD/eMMC IO solutions are also available at 22nm, 28nm, and 40nm process nodes.

Highlights

  • Support HS400 (400Mbps), HS200 (200Mbps), High-speed DDR (52Mbps) and etc.
  • Consisting of driver, receiver & pull-up/down resistors
  • Power-sequence free
  • Provide multi-driving-strength selection
  • Available in 22nm, 28nm, and 40nm process nodes
