Overview

The DQSPI is a revolutionary quad SPI designed to offer the fastest available operations for any serial SPI memory. It is flexible enough to interface directly with numerous standard product peripherals from several manufacturers. Moreover, IP Core supports all 8, 16, 32 bit processors available on the market. The DQSPI is a fully configurable SPI master/slave device, which allows user to configure polarity and phase of serial clock signal SCK. It lets the microcontroller to communicate with fast serial SPI memories and serial peripheral devices. Moreover, it's capable of interprocessor communications in a multi-master system.

Features

  • Operates with 8, 16 and 32 bit CPUs; Full duplex synchronous serial data transfer; DMA support; Support for 32, 16 and 8 bit systems
  • Support for various system Bus Standards; Single, Dual and Quad SPI transfer; DDR support (Double Data Rate)
  • Optionally available Execute-in-Place; Multimaster system supported; Optional FIFO size extension (128, 256, 512B)
  • Up to 8 SPI slaves can be addressed; System error detection; Interrupt generation; Various Bit rates supported
  • Bit rate in fast SPI Mode ½ CLK; Four transfer formats; Simple SPU and DMA interface
