SPI Controller

SPI Controller

Dolphin Technology provides Serial Peripheral Interface (SPI) IP which enables an AHB/APB host to access a serial device at high-speed through the SPI interface. The controller supports both Master and Slave modes and consists of a DMA controller to enhance the system performance. The IP can be used in applications such as flash memory card and digital camera.
