24LC025T-E/MNY

Memory IC Overview

The Microchip Technology 24LC025T-E/MNY is a 2 Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible 2-wire 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 features a maximum write cycle time of 5 ms, hardware write protection capabilities, and high endurance exceeding one million erase/write cycles with data retention greater than 200 years. It is housed in an 8-lead TDFN package and rated for an extended industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using hardware address pins A0, A1, and A2.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Features a 16-byte page write buffer for efficient data transfer operations.
• Provides hardware write protection via the WP pin to secure memory arrays.

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial controllers needing reliable data logging under extreme temperatures
• Automotive electronics demanding high endurance and noise immunity

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm the presence of the write-protect pin functionality if hardware security is necessary for the design. Ensure compatibility with the system's I²C bus voltage levels and pull-up resistor requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when an automotive-grade temperature rating (-40°C to +125°C) is required alongside standard I²C connectivity. It is suitable for designs prioritizing physical robustness through its TDFN packaging and noise suppression features. Consider alternatives only if lower voltage operation below 2.5V or different package constraints are mandatory.

Memory IC Part Context

This part belongs to the 24LC025 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA025 but differs in operating voltage specifications. The 'E' suffix denotes the extended temperature range, while '/MNY' specifies the TDFN-8 package variant.

Memory IC Replacement Considerations

Direct substitutes within the same family include other 24LC025 variants with different packages such as SOT-23-6 or TSSOP-8. Cross-family replacements like the 24AA025 require verification of voltage level compatibility.
