The SD Memory Slave Controller IP Core from iWave enables seamless integration of FPGA-based systems with external SD Memory Cards in slave mode. Designed to meet SD Memory Card Physical Layer Specification Version 2.0, this IP core allows efficient data communication through a simple command-response protocol. It acts as a bridge between the host processor and external SD memory cards, allowing FPGAs to emulate memory storage functionality in a highly configurable manner.

The controller supports SPI and SD modes with features like block-based data transfers, CRC generation/checking, and interrupt-driven operations. This makes it ideal for a range of embedded applications such as portable data recorders, industrial logging equipment, and consumer electronics requiring removable storage options. It is optimized for low-resource utilization and offers flexibility with easy integration into designs using standard AXI interfaces.
