SST25VF040B-50-4I-SAE-T Frequently Asked Questions (FAQs)

  • The SST25VF040B has a minimum of 100,000 erase cycles, but the actual number of cycles may vary depending on the usage and operating conditions.
  • The hold pin (HOLD#) is used to pause the serial flash memory operation. To use it, connect the HOLD# pin to the system's control signal, and assert it low to pause the operation. De-assert the HOLD# pin to resume the operation.
  • The recommended power-up sequence is to apply VCC first, followed by the clock signal (SCK), and then the chip select (CS#) signal. This ensures proper initialization of the device.
  • Yes, the SST25VF040B is compatible with 3.3V power supplies. The device operates from a single 2.7V to 3.6V power supply, making it suitable for 3.3V systems.
  • The WP# (Write Protect) pin is used to prevent accidental writes to the device. Connect the WP# pin to VCC to enable write protection, or connect it to GND to disable write protection.
