Frequently Asked Questions
What is the storage capacity and page write buffer size of the 24LC32AFT-I/OT?
The 24LC32AFT-I/OT provides 32 Kbit (4096 x 8 bytes) of I2C EEPROM storage and a 32-byte page write buffer. This combination allows efficient burst writes and supports industrial applications needing reliable non-volatile storage for calibration tables, configuration settings, or user data in a 2.5V to 5.5V operating range.
When is the 24LC32AFT-I/OT in SOT-23-5 a better fit than a larger PDIP EEPROM for a compact IoT sensor node?
For compact IoT sensor nodes where board space is critical, the 24LC32AFT-I/OT in a SOT-23-5 package (approximately 3 mm x 1.75 mm footprint) occupies far less PCB area than an 8-pin PDIP while delivering the same 32 Kbit capacity at 400 kHz I2C. Its 2.5V to 5.5V supply range matches 3.3V systems common in low-power IoT designs.
How does the 24LC32AFT-I/OT endurance hold up in write-intensive industrial data logging over a 10-year product life?
The 24LC32AFT-I/OT guarantees 1,000,000 write/erase cycles per byte and a minimum 200-year data retention. For a 10-year product life requiring one configuration update per day across the full 4096-byte address space, actual cycle utilization remains well below the 1 million cycle endurance limit, ensuring reliable data integrity throughout the industrial product lifetime.
What is the factory lead time for the 24LC32AFT-I/OT, and is it RoHS compliant?
The 24LC32AFT-I/OT has a factory lead time of 6 weeks and is fully RoHS compliant, carrying a Pb-free designation with a JESD-609 e3 rating. It is available in the SOT-23-5 (R-PDSO-G6) surface-mount package, supporting eco-compliant manufacturing for global industrial and consumer electronics production.
