SPI Memory Controller

Reading memory is performed by directly accessing the memory using reads on a AHB slave interface. Other operations, e.g. writes, are performed by sending SPI commands using the core's register interface. The SPIMCTRL supports most SPI Flash devices.

The IP can be implemented in any ASIC or FPGA technology. For specific information related to Xilinx, Microchip, and Lattice FPGAs, please refer to our dedicated web pages:
