SD Card Controller

Integrates MAC IP to a broad range of PHY and SerDes IP

Overview

An SD (Secure Digital) Card Controller is a crucial component in devices such as cameras, smartphones, and tablets that use SD cards for storage. It manages the interface between the SD card and the host device, facilitating data transfer, storage management, and ensuring compatibility with various SD card standards.

Features

  • Command Processing: Handles commands from the host device to the SD card, including read, write, erase, and format operations.
  • Data Transfer Speeds: Supports various data transfer modes (e.g., High-Speed, UHS-I, UHS-II) to maximize data throughput between the host and SD card.
  • Error Detection and Correction: Implements mechanisms to detect and correct data errors, ensuring data integrity and reliability.
  • Power Management: Manages power consumption efficiently, optimizing battery life in portable devices.
  • Security Features: Implements SD card security protocols (e.g., CPRM, SDMI) to protect copyrighted content and sensitive data.
  • Compatibility: Supports multiple SD card standards (SD, SDHC, SDXC, SDUC) and backward compatibility with older SD card versions.
  • Boot Functionality: Enables the SD card to be used as a boot device, allowing the host device to boot directly from the SD card.
  • Hot Plug and Play: Supports hot insertion and removal of SD cards without causing data loss or system instability.
  • Clock Management: Generates and synchronizes clock signals required for SD card communication.
  • Bus Protocol Handling: Manages the low-level bus protocols (e.g., SPI, UHS-I, UHS-II) required for data transfer between the host and SD card.
