S29GL128S90DHI013 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The maximum operating temperature range for the S29GL128S90DHI013 is -40°C to +85°C.
• How do I handle the hold signal (HOLD#) during active operations?
  The hold signal (HOLD#) should be kept high during active operations. If the hold signal is asserted low, the device will enter a 'hold' state, and all operations will be suspended.
• What is the purpose of the write protect (WP#) signal?
  The write protect (WP#) signal is used to prevent accidental writes to the device. When WP# is low, the device is in a protected state, and all write operations are inhibited.
• How do I determine the device density and organization?
  The S29GL128S90DHI013 is a 128 Mbit (16 Mbyte) flash memory device, organized as 2,097,152 words of 8 bits each.
• What is the recommended power-up sequence for this device?
  The recommended power-up sequence is to apply VCC first, followed by VPP (if used), and then the clock signal. This ensures proper device initialization and prevents latch-up.
