24LC025-E/P

Memory IC Overview

The Microchip Technology 24LC025-E/P is a 2 Kbit (256 x 8) Serial Electrically Erasable PROM featuring an I²C compatible 2-wire serial 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 is housed in an 8-lead PDIP package and is rated for an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology with typical standby current of 1 μA
• Hardware write protection capability via the WP pin
• Schmitt trigger inputs for noise suppression
• Supports cascading up to eight devices on the same bus

Memory IC Applications

• Personal communications equipment
• Data acquisition systems
• Industrial control applications

Memory IC Procurement Notes

Verify that the specific part number suffix matches the required package type, as the datasheet indicates multiple options including SOIC, TSSOP, DFN, and MSOP. Confirm the temperature grade corresponds to the intended operating environment, distinguishing between Industrial and Automotive ratings. Ensure the ordering code aligns with the desired lead time and packaging format.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires a standard 8-pin through-hole DIP footprint for prototyping or legacy board designs. The 24LC025-E/P variant specifically targets automotive environments requiring extended temperature ranges compared to the standard industrial version. Consider the lack of hardware write protection if security against accidental writes is not a primary design constraint.

Memory IC Part Context

This component belongs to the 24LC025 series of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA025 and 24LC024 models but differs in voltage requirements and write protection features. The 'E' designation typically denotes an extended temperature range suitable for automotive applications.

Memory IC Replacement Considerations

Public confirmed substitute part numbers: 24LC025-I/P, 24LC025T-I/OT, 24LC025-E/SN.
