Key Features

  • 512Kbit high-density EEPROM organized as 64K x 8 bytes for large parameter and data storage needs
  • 400kHz fast-mode I2C interface enabling rapid read and write transactions in bandwidth-sensitive applications
  • 1 million write/erase cycle endurance and 200-year data retention for long-lasting embedded storage
  • Configurable I2C address pins allow up to eight devices on a single bus, scaling total capacity to 4Mbit

Applications

The 24LC512-I/SM is well suited for storing large configuration tables, firmware parameters, and user data in industrial PLCs, medical devices, and smart metering systems that demand high-density non-volatile storage over extended product lifetimes. Its 400kHz I2C interface and compact SOIJ-8 package simplify integration into existing two-wire bus designs in networking equipment, automotive accessories, and IoT edge nodes.

Frequently Asked Questions

What is the memory capacity of the 24LC512-I/SM?

The 24LC512-I/SM provides 512Kbits of EEPROM organized as 65,536 bytes (64K x 8), making it suitable for applications that need to store large lookup tables, event logs, or extensive calibration data in a single device.

What is the maximum I2C clock speed of the 24LC512-I/SM?

The device supports the I2C fast mode with a maximum clock frequency of 400kHz (0.4MHz), significantly reducing the time needed to transfer larger data blocks compared to the standard 100kHz mode.

How many 24LC512-I/SM devices can be used on a single I2C bus?

Up to eight 24LC512 devices can share a single I2C bus by setting different combinations on the three address pins (A0, A1, A2), providing up to 4Mbit (512KB) of total EEPROM capacity without additional bus hardware.

What is the write endurance and data retention specification?

The 24LC512-I/SM guarantees at least 1,000,000 write/erase cycles per byte and a minimum data retention period of 200 years at room temperature, ensuring reliable long-term operation in high-write-cycle applications.

Is the 24LC512-I/SM in stock and RoHS compliant?

Yes, the 24LC512-I/SM is available in stock worldwide and carries JESD-609 code e3 confirming lead-free, RoHS-compliant manufacture, meeting current EU RoHS and international environmental directives for electronic components.
