24LC025T-I/SN

Memory IC Overview

The Microchip Technology 24LC025T-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 with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, offering typical standby current of 1 μA and active read current of 1 mA. It supports page write operations with a 16-byte buffer and includes Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard two-wire serial bus protocol
• Includes hardware address pins allowing up to eight devices on the same bus
• Features internal self-timed erase/write cycles with automatic acknowledge polling

Memory IC Applications

• Personal communication systems requiring non-volatile data storage
• Data acquisition applications needing low power consumption
• Industrial control systems operating within industrial temperature ranges

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the 'SN' designation indicates an 8-lead SOIC package. Confirm the temperature grade corresponds to the intended operational environment. Ensure the source documentation explicitly lists the 24LC025 variant, as pinouts and features differ from the 24LC024 model regarding write protection capabilities.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for the application requirements. Choose this part over the 24LC024 if hardware write protection is not required or will be managed by software logic. Verify that the system voltage remains above 2.5V to ensure proper operation within the specified electrical characteristics.

Memory IC Part Context

This component belongs to the 24AA024/24LC024/24AA025/24LC025 family of serial EEPROMs. It shares the same physical footprint and interface protocols as other members of the series but differs in specific electrical parameters and feature sets, such as the absence of a dedicated write-protect pin found in the 24XX024 variants.

Memory IC Replacement Considerations

Direct replacements include the 24LC024T-I/SN, provided the application does not require the hardware write-protect functionality unique to the 24LC024. Other compatible parts within the same datasheet include the 24AA025T-I/SN, though voltage range specifications must be verified against the system design.
