SST39SF040-55-4C-WHE Frequently Asked Questions (FAQs)

  • The SST39SF040-55-4C-WHE has an operating temperature range of -40°C to +85°C.
  • The SST39SF040-55-4C-WHE requires a power-up sequence of VCC followed by VPP, and a power-down sequence of VPP followed by VCC. This ensures proper device operation and prevents latch-up.
  • The SST39SF040-55-4C-WHE has a maximum clock frequency of 33 MHz, but it's recommended to operate at 20 MHz or lower for reliable operation.
  • To prevent bus contention, ensure that only one device is driving the bus at a time. For bus loading, use a pull-up resistor of 1 kΩ to 10 kΩ on the CE# and OE# pins to prevent overloading.
  • The SST39SF040-55-4C-WHE has a minimum erase cycle endurance of 10,000 cycles, with a typical value of 100,000 cycles.
