The S25FL256SAGBHAA03 has a minimum of 100,000 erase cycles per sector, and a minimum of 10,000 erase cycles per block.
The HOLD# pin should be driven high during low power modes to prevent unwanted writes or erases. It's recommended to use an external pull-up resistor to ensure the pin is held high.
The recommended method is to use the RY/BY# pin, which goes low during a program or erase operation and returns high when the operation is complete. Alternatively, you can use the EWSR (Enable Write Status Register) bit to poll the status register.
The WP# pin should be driven high during power-up and power-down sequences to prevent unwanted writes or erases. It's recommended to use an external pull-up resistor to ensure the pin is held high.
The S25FL256SAGBHAA03 has a maximum operating frequency of 104 MHz.
