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

Device Utilization and Performance

Intel® Cyclone® IV E Logic Element combinational - 1804 Logic Element Registers - 1494 Embedded Multipliers 9 bit Elements -2

Getting Started

1. Helps to emulate the SD card in test card application 2. Core handles SD bus protocol on the card interface and provides simplified interface to user logic 3. Can be used as bridge core between SD memory to custom application 4. Core handle all the housekeeping tasks by itself without user logic intervention 5. Supports both the standard and High capacity operation
