Key Features
- 512Kbit (64K x 8) I2C EEPROM at 400kHz provides double the capacity of 256Kbit devices for larger non-volatile data storage needs
- 1,000,000 write/erase cycle endurance with 200-year minimum data retention ensures long-term reliability in demanding applications
- 2.5V low-voltage operation in a 14-pin TSSOP package with I2C address selection supports multi-device bus expansion
Applications
The 24LC512-I/ST14 is used in embedded systems requiring substantial non-volatile storage, such as industrial PLCs, medical instruments, and telecommunications equipment storing configuration tables, calibration data, or event logs. Its 14-pin TSSOP package with multiple address pins allows up to eight devices on a single I2C bus, providing up to 4Mbit of total storage without additional bus components. The combination of high endurance and long data retention makes it reliable in write-intensive data logging and firmware parameter storage applications.

Frequently Asked Questions
What is the memory capacity of the 24LC512-I/ST14?
The 24LC512-I/ST14 provides 512Kbit of non-volatile EEPROM storage, organized as 64,768 x 8-bit (64K bytes). This capacity is twice that of the 256Kbit 24FC256, making it suitable for applications requiring larger configuration tables, event logs, or calibration data sets.
What is the maximum I2C clock frequency supported by the 24LC512-I/ST14?
The 24LC512-I/ST14 supports a maximum I2C clock frequency of 400kHz (fast-mode I2C). This allows faster read and write operations compared to 100kHz standard-mode devices, reducing the time microcontrollers spend waiting for EEPROM access to complete in time-sensitive applications.
How many write/erase cycles does the 24LC512-I/ST14 support and what is its data retention?
The 24LC512-I/ST14 is rated for 1,000,000 write/erase cycles per memory location with a minimum data retention time of 200 years. This high endurance and long retention make it reliable for applications with frequent updates such as runtime counters, real-time data logging, and firmware parameter storage.
What package does the 24LC512-I/ST14 come in?
The 24LC512-I/ST14 comes in a 14-pin TSSOP (Thin Shrink Small Outline Package) with manufacturer code TSSOP-14 and JESD-30 code R-PDSO-G14. The additional pins compared to the 8-pin SOIC version provide more address select lines, allowing more devices to share the same I2C bus in large-storage applications.
