S25FL256SAGMFI001 Frequently Asked Questions (FAQs)

• What is the maximum number of erase cycles for this device?
  The S25FL256SAGMFI001 has a minimum of 100,000 erase cycles per sector, and a minimum of 10,000 erase cycles per block.
• How do I handle the hold signal (HOLD#) during read and write operations?
  The HOLD# signal should be asserted low to pause the current operation, and de-asserted high to resume the operation. During hold, the device will tri-state its outputs and ignore any further input.
• What is the recommended method for detecting the end of a write operation?
  The device provides a Write-In-Progress (WIP) bit in the Status Register that can be polled to determine when a write operation is complete. Alternatively, the Ready/Busy# (RB#) signal can be used to indicate when the device is ready to accept the next command.
• How do I handle errors during write operations?
  The device provides an Error Interrupt (EI) signal that can be used to detect errors during write operations. The Status Register also provides error flags that can be polled to determine the type of error that occurred.
• What is the recommended method for erasing the entire device?
  The Chip Erase (CE) command can be used to erase the entire device. This command erases all sectors and blocks, and sets all bytes to FFh.
