What are the key features of 24LC1025-E/SN?
- 1 Mbit (128 KB) storage capacity for large non-volatile data logging and configuration storage in embedded systems
- Up to 1,000,000 write-erase cycle endurance enabling high-frequency data update applications without wear-out concerns
- Minimum 200-year data retention ensuring long-term storage of calibration data and firmware parameters
- Standard I2C interface at up to 100 kHz with hardware address pins supporting up to 4 devices on a single 2-wire bus
What is 24LC1025-E/SN used for?
The 24LC1025-E/SN is used for non-volatile storage of configuration data, calibration tables, and event logs in industrial controllers, medical instruments, and embedded computing modules that require reliable long-term data retention up to 200 years. Its 1 Mbit capacity supports larger data sets such as firmware parameter blocks, lookup tables, and accumulated sensor logs compared to smaller 256 Kbit or 512 Kbit EEPROM alternatives. The I2C interface and SOIC-8 package simplify integration into existing 2-wire bus designs with minimal additional routing.

Frequently Asked Questions
How much data can 24LC1025-E/SN store and how many write cycles does it support?
The 24LC1025-E/SN stores 1 Mbit (128 KB) of non-volatile data and supports a minimum of 1,000,000 write-erase cycles per byte location. This write endurance is sufficient for applications that update stored data at rates of several hundred writes per day over a 10-year product lifetime without exceeding the endurance specification.
How long does 24LC1025-E/SN retain data without power applied?
Microchip specifies a minimum data retention time of 200 years for 24LC1025-E/SN under standard storage conditions. This far exceeds the operational lifetime of virtually any embedded product, making it suitable for archiving calibration constants, device serial numbers, and configuration data that must survive decades of storage or field deployment.
How many 24LC1025-E/SN devices can share a single I2C bus, and how are they addressed?
Up to 4 devices can be connected on a single I2C bus simultaneously using the hardware address select pins (A1 and A0) in combination with the bank select bit in the I2C control byte (1010MDDR format). This allows a total of 4 Mbit (512 KB) of addressable EEPROM storage on a 2-wire I2C bus operating at up to 100 kHz without additional multiplexing hardware.
How does 24LC1025-E/SN compare to a 512 Kbit EEPROM for data-logging applications?
The 24LC1025-E/SN provides twice the storage capacity of a 512 Kbit device in the same SOIC-8 footprint and with an identical I2C interface. For data-logging applications recording timestamped sensor readings at 64 bytes per entry, the 128 KB capacity can hold approximately 2,000 records compared to 1,000 records for a 64 KB EEPROM, doubling the logging interval before the buffer must be offloaded to a host system.
