24AA024T-I/MNY

Memory IC Overview

The Microchip Technology 24AA024T-I/MNY is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It features a 2-wire I²C compatible interface with a maximum clock frequency of 400 kHz. The device operates on a single supply voltage ranging from 1.7V to 5.5V and supports industrial temperature grades from -40°C to +85°C. It utilizes low-power CMOS technology, offering typical standby current of 1 μA and active read current of 1 mA. The component is housed in an 8-lead TDFN package.

Memory IC Feature Summary

• Hardware write protection via the WP pin for data security
• 16-byte page write buffer for efficient data transfer
• Schmitt trigger inputs and output slope control for noise suppression
• Supports cascading up to eight devices on a single bus

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention for sensor modules
• Device identification and unique ID storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range compatibility with the target system's power supply rails. Ensure the design accounts for the hardware write-protect functionality inherent to the 24XX024 series. Cross-reference the datasheet revision to confirm interface timing specifications.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM capacity is required within a compact surface-mount footprint. It is suitable for applications needing wide voltage operation down to 1.7V. Consider the 24LC024 variant if the system voltage does not drop below 2.5V. Verify that the I²C bus speed requirements align with the 400 kHz maximum specification.

Memory IC Part Context

This part belongs to the 24AA024/24LC024 family of serial EEPROMs manufactured by Microchip Technology. These devices are designed for general-purpose non-volatile memory applications where space and power consumption are critical constraints. The family shares functional similarities but differs in voltage ranges and package options.

Memory IC Replacement Considerations

Direct replacements include other 24AA024 variants with different packages such as SOIC or TSSOP. The 24LC024 is functionally similar but requires a minimum operating voltage of 2.5V. Ensure any substitute maintains the same I²C addressing scheme and page write buffer size.
