Getting Started

To integrate this flash memory, use standard SPI or Quad SPI (QSPI) drivers available in most MCU HALs. Engineers should pay attention to the Program Suspend/Resume features to manage timing-critical tasks during write operations. Verification can be performed using standard SPI flash programmers or via the manufacturer-specific ID read commands.
