Overview

The SD Memory Slave controller is designed to reside within SD Memory card. This slave controller provides simple and general-purpose 8-bit interface to user application. This controller handles the SD bus protocol on the card interface side and forwards only the data transfer requests to user logic interface.

Features

  • Compliant with SD Physical Specification Version 2.00 & Supports 1-bit and 4-bit SD Mode
  • Supports Single and Multiple block read and write data transfer & Supports Partial and Misalign Block length option
  • CID Register fields are configurable through header file & CRC16 checking/generation for Data transfer
  • Supports all mandatory SD Command Classes & CRC7 checking/generation for Command/Response
  • Supports Default and High Speed Modes of operation & Supports Standard and High Capacity operations

Getting Started

1. Helps to emulate the SD card in test card application2. Core handles SD bus protocol on the card interface and provides simplified interface to user logic3. Can be used as bridge core between SD memory to custom application4. Core handle all the housekeeping tasks by itself without user logic intervention5. Supports both the standard and High capacity operation
