24LC025T/SN

Memory IC Overview

The Microchip Technology 24LC025T/SN is a 2 Kbit (256 x 8) Serial Electrically Erasable PROM featuring an I2C-compatible 2-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies of up to 400 kHz. The device utilizes low-power CMOS technology with typical standby current of 1 μA and read current of 1 mA. It includes a 16-byte page write buffer, hardware write protection capabilities via the WP pin (though not internally connected on this specific model), and Schmitt trigger inputs for noise suppression. The component is housed in an 8-lead TSSOP package and is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard 2-wire serial bus protocol compatible with I2C™.
• Features a 16-byte page write buffer to optimize write operations and reduce cycle times.
• Incorporates Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce.
• Provides high reliability with over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Applications

• Data acquisition systems requiring non-volatile storage for sensor calibration values.
• Personal communication devices needing low-power configuration memory.
• Industrial control applications utilizing I2C bus architectures for parameter logging.
• Embedded systems storing user settings or device identification data.

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the '/SN' designation matches the 8-lead SOIC or TSSOP physical footprint specifications for your PCB layout. Ensure the 'I' temperature grade aligns with the operational environment requirements of -40°C to +85°C. Cross-reference the manufacturer part number against official Microchip databases to confirm current production status and RoHS compliance before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM capacity is required within an I2C-based system architecture. Choose this specific variant if the application demands operation within the 2.5V to 5.5V voltage range rather than the lower 1.7V range offered by AA series counterparts. Consider this part for designs necessitating the TSSOP surface-mount package form factor. Evaluate the 400 kHz maximum clock speed against system bus timing constraints to ensure adequate data throughput performance.

Memory IC Part Context

This device belongs to the Microchip 24AA024/24LC024/24AA025/24LC025 family of serial EEPROMs. It shares functional similarities with the 24LC024 but offers double the memory density. Unlike the 24XX024 variants, this model lacks internal hardware write protection circuitry on the WP pin. It serves as a direct upgrade path for legacy 1 Kbit EEPROM designs requiring expanded storage capacity while maintaining pin compatibility and interface standards.

Memory IC Replacement Considerations

Direct substitutes include the 24LC025-I/SN (SOIC package) and 24LC025-I/P (PDIP package). For automotive-grade requirements, consider the 24LC025-E variants. Verify package dimensions and pinout compatibility when replacing with generic I2C EEPROMs from other manufacturers.
