SST39SF512-90-4C-NH datasheet by Silicon Storage Technology

SST39SF512-90-4C-NH Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this device?
  The SST39SF512-90-4C-NH has an operating temperature range of -40°C to +85°C.
• How do I handle power-up and power-down sequences for this device?
  The device requires a controlled power-up sequence to ensure proper operation. A power-on reset (POR) circuit is recommended to ensure a clean power-up. During power-down, the device should be deselected (CE# high) and placed in standby mode to minimize power consumption.
• What is the recommended clock frequency for this device?
  The SST39SF512-90-4C-NH has a maximum clock frequency of 90 MHz. However, the recommended clock frequency is 66 MHz to ensure reliable operation and minimize power consumption.
• How do I handle bus contention and bus loading for this device?
  To prevent bus contention, ensure that only one device is active on the bus at a time. Use a pull-up resistor on the CE# pin to prevent bus loading. Additionally, use a buffer or a latch to isolate the device from the system bus.
• What is the erase cycle endurance for this device?
  The SST39SF512-90-4C-NH has a minimum erase cycle endurance of 100,000 cycles. However, this can vary depending on the operating conditions and usage patterns.
