DesignWare Synchronous Serial Interface (SSI)

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 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 Semiconductors Microwire

Supporting such features allows the single IP instance to interact with multiple connected devices which may support 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. Depending on the configuration the IP can work in one of the following modes:

  • Serial Master/Slave configuration with AHB slave programming interface
  • Serial Master configuration with AHB slave programming interface and AXI Master interface for data transfers
  • Bridge mode configuration for Serial Slave with AHB/APB slave programming interface and AHB Master interface for data transfers
  • The IP architecture leverages power management techniques, making it ideal for low-power applications. The highly configurable and scalable IP is packaged with Synopsys coreConsultant tool and is optimized to reduce gate count and power consumption.

    • Supports 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 Semiconductors Microwire
    • Supports serial clock rates of 133MHz in SDR and 80 MHz in DDR for SPI transfers
    • Programmable delay on the sample time of received serial data bit which enables programmable control of routing delays resulting in higher serial data-bit rates
    • Execute-in-Place (XIP) mode supports SPI read and write transfers
    • External DMA controller interface enables the IP to interface with a DMA controller over the bus using handshaking interface for transfer requests
    • Internal DMA controller enables the IP to interface with internal AXI Slaves and SPI serial interface without any software intervention
    • SPI bridge configuration for SPI bridge operation to convert all the incoming SPI transactions into corresponding AHB transactions
