The CY14B108N-BA45XIT has an operating temperature range of -40°C to +85°C.
To implement a battery backup system, connect a battery to the VCC pin and a diode (e.g., 1N4148) between the battery and the VCC pin. This allows the battery to take over when the main power supply fails.
The maximum clock frequency for the I2C interface is 400 kHz.
Page writes are limited to 8 bytes, and block writes are limited to 32 bytes. The device automatically increments the address pointer after each byte is written. Make sure to send a stop condition after each write operation.
The WP (Write Protect) pin is used to prevent accidental writes to the device. When the WP pin is tied low, the device is in write-protect mode, and any write attempts will be ignored. When the WP pin is tied high or left floating, the device is in normal operation mode.
