Key Features
- 1 Mbit capacity with 20 MHz SPI interface delivers fast sequential read performance for data-logging and configuration storage
- 1,000,000 write/erase cycle endurance with 200-year data retention ensures long-term reliability in industrial and IoT deployments
- Compact DFN-8 package at 2 mm × 3 mm enables high-density non-volatile storage in space-constrained embedded designs
Applications
25LC1024T-I/MF is used in embedded systems and IoT devices for non-volatile storage of calibration data, configuration parameters, and firmware update records where an SPI interface at up to 20 MHz is required. It suits industrial sensor nodes, smart meters, and medical devices that demand 200-year data retention and 1,000,000 write cycles for reliable long-term field operation. The DFN-8 package also makes it a compact choice for wearables and wireless modules where PCB footprint is tightly constrained.

Frequently Asked Questions
What is the maximum SPI clock frequency and endurance of 25LC1024T-I/MF?
25LC1024T-I/MF supports a maximum SPI clock frequency of 20 MHz and guarantees 1,000,000 write/erase cycles per word with a minimum data retention of 200 years, making it one of the most durable 1 Mbit EEPROM options for industrial and long-lifecycle embedded applications.
For a smart meter design, how does 25LC1024T-I/MF's endurance compare to the typical write frequency requirements?
A smart meter writing energy consumption data once per minute would perform about 525,600 writes per year; with 1,000,000 guaranteed write/erase cycles, 25LC1024T-I/MF provides nearly 2 years of continuous data logging per memory location without wear-out, and combining wear-leveling across the 1 Mbit address space extends the effective lifetime to over a decade.
How small is the 25LC1024T-I/MF DFN-8 footprint, and why does that matter for wearable designs?
The DFN-8 package of 25LC1024T-I/MF measures 2 mm × 3 mm with a 0.5 mm pitch, which is roughly 50% smaller than a standard SOIC-8 footprint, allowing wearable and hearing aid designers to allocate more PCB area to battery or antenna while still incorporating 1 Mbit of non-volatile SPI EEPROM storage operating from a 2.5 V to 5.5 V supply.
