24LC025-I/SN

Memory IC Overview

The Microchip Technology 24LC025-I/SN is a 2 Kbit (256 x 8) serial electrically erasable PROM featuring an I²C-compatible interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology with typical standby current of 1 μA and active read current of 1 mA. It includes a 16-byte page write buffer, hardware write protection capabilities are absent for this specific model, and offers over one million erase/write cycles with data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication via I²C compatible protocol
• Includes Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Features self-timed erase/write cycles with automatic acknowledge polling
• Provides hardware address selection allowing up to eight devices on the same bus

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications equipment
• Industrial control applications
• Consumer electronics utilizing I²C buses

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C). Confirm the '/SN' suffix indicates the 8-lead SOIC package. Ensure the specific part number matches the required voltage range of 2.5V to 5.5V, as other variants in the family may support lower voltages. Check datasheet revisions for any manufacturing changes or pinout updates before finalizing procurement.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM with I²C interface is required within the industrial temperature range. Note that unlike the 24LC024 variant, this device lacks a hardware write-protect pin; write protection must be managed via software or external circuitry. Ensure the system voltage remains above 2.5V to maintain 400 kHz clock compatibility. Consider the 16-byte page buffer size when designing write algorithms to prevent data rollover across page boundaries.

Memory IC Part Context

This device belongs to the 24AA024/24LC024/24AA025/24LC025 family of serial EEPROMs. It shares architectural similarities with the 24LC024 but differs in the absence of a hardware write-protect pin. The 'I' designation specifies the industrial temperature grade, while '/SN' identifies the plastic small outline package. It serves as a low-cost, low-power memory solution for embedded systems requiring reliable non-volatile data storage.

Memory IC Replacement Considerations

Direct substitutes include the 24LC024-I/SN, which offers identical specifications except for the inclusion of a hardware write-protect pin. Other family members like the 24AA025 share similar electrical characteristics but operate at lower minimum voltages.
