24AA024-I/MS

Memory IC Overview

The Microchip Technology 24AA024-I/MS is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 1.7V to 5.5V and features a 2-wire I²C compatible serial interface with a maximum clock frequency of 400 kHz. The device supports hardware write protection via the WP pin, utilizes low-power CMOS technology, and includes Schmitt trigger inputs for noise suppression. It 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

• Hardware write protection enabled by connecting the WP pin to VCC
• Low-power operation with typical standby current of 1 μA
• Supports cascading up to eight devices on a single bus
• Includes Schmitt trigger inputs for enhanced noise immunity

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing I²C communication protocols
• Embedded systems needing configuration parameter retention
• Automotive applications operating within specified temperature ranges

Memory IC Procurement Notes

Verify that the specific part number corresponds to the Industrial temperature grade (-40°C to +85°C) and the MSOP package style. Confirm compatibility with the system's I²C bus voltage levels, as the device supports a wide range from 1.7V to 5.5V. Ensure the application design accounts for the hardware write-protect functionality if data integrity during writes is critical.

Memory IC Selection Notes

Select this component when a small capacity EEPROM with I²C interface is required for industrial environments. It is suitable for designs needing hardware-level write protection to prevent accidental data modification. Consider the MSOP package for space-constrained printed circuit board layouts. Verify that the system power supply remains within the 1.7V to 5.5V operational range for reliable performance.

Memory IC Part Context

This device belongs to the 24AA024/24LC024 family of 2 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC024 but differs in its minimum operating voltage, supporting operation down to 1.7V compared to the 2.5V minimum of the LC variant. The 'I' suffix denotes the industrial temperature rating, while '/MS' specifies the 8-lead Mini Small Outline Package.

Memory IC Replacement Considerations

The 24LC024-I/MS is a direct functional substitute, provided the system voltage does not drop below 2.5V. Other members of the 24AA02x series may be considered if different memory capacities are acceptable.
