------------------------------------------------------------------------------- Winbond W25Q80D ------------------------------------------------------------------------------- These are example captures of a Winbond W25Q80DV (8MBit == 1MByte) SPI flash chip being driven by a Teensy 3.2. The SPI clock is at 500kHz.
