To face these requirements, STM32 devices embed an external memory interface named Quad-SPI (see more details on Table 2). This interface allows the connection of external compact-footprint Quad-SPI high-speed memories. This Quad-SPI interface is used for data storage such as...
AN228740 Usage of Quad SPI (QSPI)/Serial Memory Interface (SMIF) in PSoC™ 6 MCU About this document Scope and purpose AN228740 provides the guidelines for using QSPI/SMIF in PSoC™ 6 MCU. The PSoC™ 6 MCU QSPI delivers an in...
从软件的角度来看,SPI一般是连着flash来使用,flash作为一种存储模块,软件更加期望用memory的形式访问,在SoC上经常会有从flash里面搬运数据的需求。 XIP性能 一般来说,non-xip模式下,由于可以通过寄存器配置来实现给出一个地址得到一大段的数据的操作,只要配置得当,数据读取的速率是会比xip模式下快的。 但是不同公司的...
Infineon offers a wide range of Quad SPI (QSPI) NOR flash memories based on industry-standard floating gate and proprietary MIRRORBIT™ technologies. The industry-standard Quad SPI interface is widely supported by the most widely used chipsets. For automotive applications, devices are available with...
multiple devices can be linked to a single Quad-SPI interface and the same data lines can be connected to multiple devices. To select a particular chip, the chip select pin can be used. This is an advantage since if we use a parallel memory solution we need a separate set of data lines...

HAL STM32 Driver for Winbond W25Q-series memory, using Quad-SPI interface Features: Easy applying: ST's HAL functions are used Uses Quad-SPI interface (4 lines) Supports(almost)all chip commands(later) Simple usage with data types wrapper-functions, or use raw 8-bit data ...
Am using the Qsys generic quadspi interface feeding a DMA which will read data out of the serial flash to volatile memory. I have the quadSPI interface on the Nios bus clocked at 20 MHz. When first bringing up the board and programming the CycV with Quartus (which is all good), th...
implemented:* 2 x chip select signals per flash bus (PCSFA1/2 and PCSFB1/2) to allow two serial flash memory devices to beconnected and accessed, or one dual-die package which consists of two devices (dies) stacked within the same package to increase the memory capacity of a single ...
