S29GL256S90GHI020 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The maximum operating temperature range for the S29GL256S90GHI020 is -40°C to +85°C.
• How do I handle the hold signal (HOLD#) during read and write operations?
  The HOLD# signal should be asserted low to pause the current read or write operation. De-asserting HOLD# resumes the operation from where it was paused.
• What is the purpose of the Write Protect (WP#) pin?
  The WP# pin is used to prevent accidental writes to the device. When WP# is low, the device is in write-protect mode, and all write operations are inhibited.
• How do I determine the device density and organization?
  The device density and organization can be determined by reading the Device ID and Sector Protection registers. The S29GL256S90GHI020 has a density of 256 Mbits and is organized as 16,777,216 words of 16 bits each.
• What is the recommended power-up sequence for this device?
  The recommended power-up sequence is to apply VCC first, followed by VCCQ, and then the clock signal. This ensures proper device initialization and prevents latch-up conditions.
