DesignWare Synchronous Serial Interface (SSI)

The DesignWare® Synchronous Serial Interface IP addresses the demand for high transfer rates and low latency in serial flash memories for mobile, consumer, IoT, and automotive applications. The IP supports the following standards:

  • Motorola SPI
  • Standard/Dual/Quad/Octal SPI
    • JEDEC xSPI (JESD251) v1.0
    • Micron XccelaBus
    • Cypress Semiconductors Hyperbus
  • Texas Instruments Synchronous Serial Protocol (SSP)
  • National Semiconductor Microwire

Support for such standards allows the single IP instance to interact with multiple connected devices, supporting different protocols. Advanced features such as Execute in Place (XIP), Slave Bridge mode, and Internal DMA allows easy access to the serial device and improves overall design performance. The standards-based Arm® AMBA® Advanced High-Performance Bus (AHB) or Advanced Peripheral Bus (APB) connects the IP to the rest of the SoC while the bus is connected to the register interface and the Direct Memory Access (DMA) interface, offering easy IP integration.

  • Supports the following standards:
    • Motorola SPI
      • Standard/Dual/Quad/Octal SPI
      • JEDEC xSPI (JESD251) v1.0
      • Micron XccelaBus
      • Cypress Semiconductors Hyperbus
    • Texas Instruments Synchronous Serial Protocol (SSP)
    • National Semiconductor Microwire
  • Serial clock rates of 133MHz in SDR and 200 MHz in DDR for SPI transfers
  • Programmable delay on the sample time of received serial data bit, enabling programmable control of routing delays resulting in higher serial data-bit rates
  • Execute in Place (XIP) mode for SPI read and write transfers
  • Supports boot mode
  • External DMA controller interface enables the DWC_SSI to interface to a DMA controller using handshaking interface for transfer requests
  • Internal DMA controller enables DWC_ssi to interface with internal AXI Slaves and SPI serial interface without any software intervention
  • SPI Bridge configuration converts all the incoming SPI transactions into corresponding AHB transactions
