Key Features
- 2Kb I2C Serial EEPROM with half-array hardware write protection for selective data security in industrial applications
- 1,000,000 write/erase cycles endurance with 200-year minimum data retention ensuring long-term data integrity
- Industrial-grade temperature rating in a compact SOIC-8 package with RoHS-compliant pb-free construction
Applications
The 24LC024HT-I/SN is ideal for storing configuration data, calibration parameters, and secure identifiers in industrial control systems, smart meters, and HVAC equipment operating across wide temperature ranges. Its half-array write protection feature allows critical data regions to be hardware-protected independently, making it suitable for applications where firmware parameters must be safeguarded against accidental overwrites. The I2C interface and SOIC-8 package simplify integration with industrial microcontrollers in PLCs, sensor modules, and remote monitoring devices.

Frequently Asked Questions
What does the half-array write protect feature of the 24LC024HT-I/SN do?
The half-array write protect (WP) feature of the 24LC024HT-I/SN allows the upper half of the 2Kb memory array to be hardware-write-protected independently. This protects critical calibration or configuration data from accidental overwrites while allowing the lower half to remain freely writable.
What is the maximum clock frequency and interface of the 24LC024HT-I/SN?
The 24LC024HT-I/SN communicates via I2C with a maximum clock frequency of 1 MHz (Fast-mode Plus), using the control byte 1010DDDR for addressing. Up to 8 devices can share a single I2C bus using the device address select bits.
What is the endurance and data retention specification for the 24LC024HT-I/SN?
The 24LC024HT-I/SN guarantees a minimum of 1,000,000 write/erase cycles and 200-year minimum data retention, making it reliable for high-frequency update applications like event counters and configuration storage in industrial equipment.
What package and temperature grade does the 24LC024HT-I/SN offer?
The 24LC024HT-I/SN comes in an 8-pin SOIC (JESD-30 Code R-PDSO-G8) package with an industrial temperature rating. It is pb-free and RoHS compliant (JESD-609 Code e3), suitable for industrial environments requiring robust component certification.
