24LC025T-I/MNY

Memory IC Overview

The Microchip Technology 24LC025T-I/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 page write buffer for up to 16 bytes, with a maximum write cycle time of 5 ms. It is housed in an 8-lead TDFN package and is rated for industrial temperatures between -40°C and +85°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 noise filter circuits to suppress spikes and ensure stable operation on noisy buses.
• Features output slope control designed to eliminate ground bounce during switching operations.

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the TDFN-8 package type and Industrial temperature grade. Confirm the device lacks the internal WP pin connection, as this variant does not support hardware write protection unlike the 24XX024 series. Ensure compatibility with the required 2.5V minimum supply voltage for the LC series.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small data storage needs. It is suitable for designs where hardware write protection is managed via software or external logic rather than a dedicated pin. Consider the 8-pin TDFN footprint constraints and the need for pull-up resistors on the SDA and SCL lines for proper bus operation.

Memory IC Part Context

This part belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial Electrically Erasable PROMs. The 'LC' designation indicates a 2.5V to 5.5V operating range, distinguishing it from the wider voltage AA series. The 'I' suffix denotes the Industrial temperature range, while '/MNY' specifies the 8-lead TDFN package configuration.

Memory IC Replacement Considerations

The 24LC025T-I/SN is a direct functional substitute available in an SOIC-8 package. For applications requiring hardware write protection, the 24LC024 series may be considered, though it requires different addressing logic due to the presence of the WP pin.
