The recommended operating voltage range for CY14B101KA-SP45XIT is 2.7V to 3.6V.
You can implement write protection by using the WP pin, which is an active-low input that prevents writes to the device when tied low. Additionally, you can use the Write Protect (WREN) instruction to enable or disable write operations.
The maximum clock frequency supported by the CY14B101KA-SP45XIT is 20 MHz.
During power-up, the device must be powered up monotonically, and the VCC pin should reach its minimum specified voltage before the clock signal is applied. During power-down, the device should be powered down monotonically, and the clock signal should be stopped before the VCC pin falls below its minimum specified voltage.
The CY14B101KA-SP45XIT has an endurance of 1 million cycles for the entire device, with a maximum of 100,000 cycles per sector.
