24LC025T-I/MS

Memory IC Overview

The Microchip Technology 24LC025T-I/MS 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 features an I²C compatible 2-wire serial interface with clock frequencies up to 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 maximum cycle time of 5 ms and includes a 16-byte page write buffer. The component is housed in an 8-lead MSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus for contiguous memory expansion
• Includes Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Features hardware write protection capability via the WP pin on compatible variants

Memory IC Applications

• Data storage in battery-powered systems requiring low standby current
• Configuration parameter retention in embedded controllers
• Calibration data storage for sensor arrays

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage range requirements align with the 2.5V minimum specification for the LC series. Ensure the design accounts for the absence of internal hardware write protection on the 24LC025 variant compared to the 24AA024.

Memory IC Selection Notes

Select this part when a 2 Kbit EEPROM capacity is required with I²C connectivity. The MSOP package is suitable for space-constrained surface mount designs. Note that the 24LC025 lacks the hardware write-protect pin found on the 24LC024; software-based protection must be implemented if write security is necessary.

Memory IC Part Context

This component belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial EEPROMs. It shares functional similarities with the 24AA025 but differs in operating voltage specifications. The 'I' designation indicates the industrial temperature range, while '/MS' specifies the 8-lead MSOP package configuration.

Memory IC Replacement Considerations

The 24LC025T-I/ST serves as a direct package alternative using TSSOP-8. For applications requiring hardware write protection, the 24LC024 series is the functional equivalent with added WP pin support.
