Frequently Asked Questions
How much data can the 24LC1025-I/SN store, and how quickly can it be accessed over I2C?
The 24LC1025-I/SN provides 1 Mbit (128 KB) of EEPROM storage and supports I2C clock frequencies up to 1 MHz in Fast-mode Plus operation. This combination enables rapid page reads and writes, which is useful for applications like configuration management and data logging in embedded systems with tight timing requirements.
What write endurance and data retention does the 24LC1025-I/SN guarantee?
The 24LC1025-I/SN is rated for 1,000,000 write/erase cycles per byte location, ensuring a long operational lifespan in high-write-frequency applications. Data retention is specified at a minimum of 200 years under normal storage conditions, making it suitable for long-lived equipment such as medical devices and industrial control units.
When is the 24LC1025-I/SN a better fit than an SPI-based EEPROM for a microcontroller design?
The 24LC1025-I/SN uses the 2-wire I2C interface, which conserves microcontroller I/O pins compared to the 4-wire SPI bus required by SPI EEPROMs. In designs where GPIO is scarce or multiple devices must share a bus, the I2C version with 8-pin SOIC-8 packaging reduces wiring complexity and allows up to 4 devices on one bus using the address pins.
How is the 24LC1025-I/SN addressed on the I2C bus, and how many devices can share the same bus?
The 24LC1025-I/SN uses the I2C control byte 1010MDDR, where the M and DDR bits allow address differentiation. Up to 4 devices (512 KB each half) can be addressed on a single bus, providing a combined 4 Mbit of accessible EEPROM using the 8-pin package's address pins and an operating voltage range of 2.5 V to 5.5 V.
