S29AL016D70BAI020 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this flash memory?
  The maximum operating temperature range for the S29AL016D70BAI020 is -40°C to +85°C.
• How do I handle the hold pin (HOLD#) during read and write operations?
  The hold pin (HOLD#) should be driven low to pause the current operation and high to resume it. It's recommended to use this pin to pause the operation when the device is busy or during power-down sequences.
• 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 conditions.
• How do I determine the device density and organization?
  The device density and organization can be determined by reading the device ID and manufacturer ID through the ID read command (90h). The S29AL016D70BAI020 has a density of 16 Mbits and is organized as 1024K x 16 bits.
• What is the purpose of the write protection (WP#) pin?
  The write protection (WP#) pin is used to prevent accidental writes to the device. When WP# is low, the device is write-protected, and when it's high, the device is writable.
