SST39WF400B-70-4I-MAQE Frequently Asked Questions (FAQ)

  • The SST39WF400B-70-4I-MAQE has an operating temperature range of -40°C to +85°C.

  • The HOLD# pin should be pulled high during power-up and power-down to prevent unwanted writes or erases. It's recommended to connect a pull-up resistor to VCC.

  • The recommended clock frequency for the SST39WF400B-70-4I-MAQE is up to 33 MHz. However, it's essential to check the specific clock frequency requirements for your application.

  • To ensure data integrity during power-down, it's recommended to use a power-down detection circuit to detect when VCC falls below a certain threshold (e.g., 2.5V). This allows the device to complete any ongoing operations and prevent data corruption.

  • The WP# (Write Protect) pin is used to prevent writes or erases to the entire device or specific sectors. When WP# is low, the device is in write-protect mode. It's recommended to tie WP# to VCC or use a pull-up resistor to enable write operations.
