- What is the supply voltage range for this device?
The supply voltage range is from 1.7 V to 5.5 V.
- How many program/erase cycles does the device support?
The device supports up to 1,000,000 program/erase cycles.
- What is the data retention period of the CAT24C32WI-GT3HP?
The data retention period is 100 years.
- What types of packages are available for this device?
