Frequently Asked Questions
What is the storage capacity of the 24LC1025-I/SM?
The 24LC1025-I/SM provides 1Mbit (131,072 bytes / 128KB) of serial EEPROM storage, organized for byte and page write operations over the I2C interface. This high capacity in a single 8-pin package makes it one of the largest I2C EEPROMs in a standard small outline package, suitable for applications needing extensive non-volatile data storage.
How many 24LC1025-I/SM devices can share one I2C bus?
The 24LC1025-I/SM uses an I2C control byte of 1010MDDR, where the M bit is a block select bit and the DD bits are hardware address pins. This allows up to 4 devices to share a single I2C bus, expanding the total addressable EEPROM space to 4Mbit (512KB). Each device is independently addressed for read and write operations.
What endurance and data retention does the 24LC1025-I/SM guarantee?
The 24LC1025-I/SM is rated for a minimum of 1,000,000 write/erase cycles per page, enabling reliable use in high-frequency data logging and update scenarios. Data retention is guaranteed for a minimum of 200 years under standard storage conditions. These specifications make it suitable for long-life industrial, medical, and infrastructure equipment where data integrity is critical.
What is the maximum clock frequency of the 24LC1025-I/SM?
The 24LC1025-I/SM supports a maximum I2C clock frequency of 1 MHz (fast-mode plus), enabling rapid sequential data transfers when reading or writing large blocks of data. This speed is advantageous for applications such as firmware update storage, data logging, and configuration loading, where minimizing transfer latency improves system responsiveness.
What package does the 24LC1025-I/SM use and is it RoHS compliant?
The 24LC1025-I/SM is housed in an 8-pin SOIJ package (manufacturer code SOIJ-8, JESD-30 code R-PDSO-G8), a gull-wing small outline package compatible with standard SMT assembly processes. The device is RoHS compliant with Pbfree Code Yes and JESD-609 Code e3, confirming lead-free construction suitable for environmentally regulated manufacturing environments.
