24AA00T-I/MC

Memory IC Overview

The Microchip Technology 24AA00T-I/MC is a 128-bit (16 x 8) serial Electrically Erasable PROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.8V to 5.5V, with typical active read current of 500 µA and standby current of 1 µA. The device supports clock frequencies up to 400 kHz and includes Schmitt trigger inputs for noise suppression. It offers over one million erase/write cycles and data retention exceeding 200 years. The component is housed in an 8-lead DFN package and functions within the industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.8V with minimal active and standby currents
• I²C compatible 2-wire serial interface with Schmitt trigger inputs for enhanced noise immunity
• High endurance with over one million erase/write cycles and long-term data retention
• Integrated output slope control to eliminate ground bounce during switching

Memory IC Applications

• Storage of calibration values
• Retention of identification numbers
• Recording manufacturing information

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required tape and reel packaging configuration. Confirm the industrial temperature grade matches the operational environment requirements. Ensure the voltage supply aligns with the 1.8V minimum specification for the 24AA00 variant. Check for any specific factory programming requests if pre-loaded data is necessary for the application.

Memory IC Selection Notes

Select this component when a small EEPROM capacity is sufficient for non-volatile data storage. The low-voltage capability makes it suitable for battery-powered or energy-constrained systems. The I²C interface simplifies board layout by requiring only two signal lines. Consider the DFN package size for space-constrained designs compared to larger PDIP or SOIC options.

Memory IC Part Context

This device belongs to the 24XX00 family of serial EEPROMs, which also includes the 24LC00 and 24C00 variants. While functionally similar, these versions differ primarily in their minimum operating voltage thresholds. The 24AA00 is distinguished by its ability to operate at lower voltages starting at 1.8V, whereas other family members may require higher minimum supplies.

Memory IC Replacement Considerations

Direct substitutes include the 24LC00T-I/MC and 24C00T-I/MC, provided the system voltage meets their respective minimum operating requirements.
