I suppose the SPI clock is obtained by dividing the 100MHz system clock and 25MHz is the highest divisor that doesn't exceed 30MHz. Industry Standard Pin-out and Packages; Superior Endurance: Min 20 years after 100K cycles; Flash. - status register (read, base plus 1) Disadvantages: 1. Connect to the SPI flash chip select (S#) pin via a level translator and connect to an external 2kΩ resistor pull-up to 1.35V to deselect the SPI flash by default. The end result is a single PCB footprint, ca- pable of supporting all devices mentioned in this technical note. The pinout shown above is taken from the WinBond datasheet. Note that SD cards use SPI as well as this discrete chip. Expanding the flash Serial Peripheral Interface (SPI) accesses from the current 4 I/Os (Quad SPI) to 8 I/Os (Octal SPI) increases the Serial NOR Flash throughput and provides a more efficient solution for emerging applications, while providing backwards compatibility with support for single, dual, quad, or octal I/O interfaces. The goal of the specification is the interchangeability of flash memory devices offered by different vendors. - BE: Bulk Erase; erase the whole chip Step 2: The WinBond Device Interface. Master out, slave in (MOSI) 4. Using this driver to support multiple Flash object instances at the same time enables users to drive multiple SPI Flash.

SPI devices communicate in full duplex mode using a master-slave architecture with a single master. Surprise! Since it simply sends the standard SPI NAND flash commands, it is a good idea to use a flash with ECC turned on by default and is performed by the flash itself, since errors cannot otherwise be corrected. Dual SPI serial throughput rates reach around 20 Mbps. - FAST_READ: similar to the READ command, but possibly uses a faster clock Open Source Core PC-FPGA Communication Platform. Standard CSA Z462: The 15 changes to the 2018 edition you need to know 10/2/2018 - SPI Accident prevention is a concern when working with electricity. These commands allow data to be transferred to or from the device at four times the rate of the standard SPI. Clock (SPI CLK, SCLK) 2. The xSPI standard defines a minimum set of requirements for compatibility with high-performance serial NOR flash interfaces. The pinout shown above is taken from the WinBond datasheet.
