The CY14B101LA-SZ45XIT can operate from -40°C to +85°C.
Use the VCC ramp-up and ramp-down rates specified in the datasheet to ensure data integrity during power-up and power-down. Also, use a capacitor on the VCC pin to filter out noise.
Store the device in a dry, cool place, away from direct sunlight, with a relative humidity of 60% or less, and at a temperature between -40°C and +30°C.
No, the CY14B101LA-SZ45XIT is not designed to operate in radiation-intensive environments. It does not have any radiation-hardened features.
Follow the recommended soldering and rework procedures outlined in the datasheet to prevent damage to the device. Use a soldering iron with a temperature of 260°C or less, and avoid applying excessive force or pressure.
