24LC025-E/ST

Memory IC Overview

The Microchip Technology 24LC025-E/ST is a 2 Kbit (256 x 8) serial electrically erasable PROM. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports I²C compatible 2-wire serial interfaces with clock frequencies up to 400 kHz. The device features an 8-lead TSSOP package, industrial temperature range of -40°C to +125°C, and typical standby current of 1 μA.

Memory IC Feature Summary

• Supports bidirectional data transfer via a 2-wire serial interface compatible with standard I²C protocols.
• Includes hardware write protection capabilities for secure data storage management.
• Features Schmitt trigger inputs and noise suppression circuits to ensure reliable operation in noisy environments.

Memory IC Applications

• Data acquisition systems requiring non-volatile memory storage
• Personal communication devices needing low-power configuration storage
• Industrial control applications utilizing I²C bus architectures

Memory IC Procurement Notes

Verify the specific ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) as defined in the official datasheet. Confirm that the 'ST' suffix indicates the 8-lead TSSOP package type. Ensure compatibility with the required voltage range of 2.5V to 5.5V for your specific application design.

Memory IC Selection Notes

Select this component when an I²C-compatible EEPROM with automotive-grade temperature specifications is required. The 24LC025 variant lacks the hardware write-protect pin found in the 24LC024 series; verify if software-based protection suffices for your security requirements compared to hardware-protected alternatives.

Memory IC Part Context

This part belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares common interface protocols and memory organization but differs in voltage ranges, temperature grades, and physical package options such as DFN, MSOP, and SOT-23.

Memory IC Replacement Considerations

The 24LC025-I/ST serves as the industrial temperature grade equivalent within the same package. Cross-reference with 24LC024 variants if hardware write protection is necessary, noting differences in pinout functionality regarding the WP pin availability.
