24AA00T-I/MNY

Memory IC Overview

The Microchip Technology 24AA00T-I/MNY is a 128-bit (16 x 8) Electrically Erasable PROM featuring a 2-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 1.8V to 5.5V and supports clock frequencies of 100 kHz and 400 kHz. The device utilizes low-power CMOS technology with typical read current of 500 µA and standby current of 100 nA. It is housed in an 8-lead TDFN package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Low-voltage operation down to 1.8V for enhanced power efficiency
• Schmitt trigger inputs provide noise suppression on the bus
• Output slope control eliminates ground bounce during switching
• Self-timed erase/write cycles with acknowledge polling support

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple form factors including PDIP, SOIC, TSSOP, DFN, TDFN, and SOT-23. Confirm the temperature grade corresponds to the intended operating environment. Ensure compatibility with the system's I2C bus voltage levels and pull-up resistor requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when minimal non-volatile storage is required for small data sets such as configuration parameters or identifiers. The 128-bit capacity limits its use to simple data logging or address storage. Consider the 1.8V minimum supply requirement for battery-powered applications. Verify that the TDFN package dimensions fit the available PCB space constraints.

Memory IC Part Context

This device belongs to the 24XX00 family of serial EEPROMs, which includes variants like the 24LC00 and 24C00. While sharing the same architecture and interface, these variants differ in supply voltage ranges and temperature specifications. The 24AA00 variant specifically supports lower voltage operation compared to the 2.5V minimum of the 24LC00 series.

Memory IC Replacement Considerations

Direct substitutes include other members of the 24XX00 family such as the 24LC00T-I/MNY or 24C00T-I/MNY, provided the system voltage meets their respective minimum requirements. Cross-referencing pinouts and electrical characteristics is essential when substituting between different package types within the same family.
