The DSPI_FIFO is a fully configurable SPI master/slave device, which allows you to configure polarity and phase of a serial clock signal SCK. It allows a microcontroller to communicate with serial peripheral devices, but also to communicate with an interprocessor in a multi-master system. A serial clock line (SCK) synchronizes shifting and sampling of the information on two independent serial data lines. The DSPI_FIFO data is simultaneously transmitted and received. What's more important, this is a technology independent design, that can be easily implemented in a variety of process technologies. The DSPI_FIFO system is flexible enough, to interface directly with numerous standard product peripherals, from several manufacturers. The system can be configured as a master or as a slave device, with data rates as high as CLK/4.


  • SPI Master; SPI Slave; SPI Slave; Two DMA Modes allows single and multi-transfer
  • In the FIFO mode transmitter and receiver are each buffered with 16/64 byte FIFO's to reduce the number of interrupts pre-sented to the CPU
  • Optional FIFO size extension to 128, 256 or 512 Bytes; Available system interface wrappers: AMBA - APB Bus, Altera Avalon Bus, Xilinx OPB Bus
  • Static synchronous design; Positive edge clocking and no internal tri-states; Scan test ready
