24AA00T-I/SN

Memory IC Overview

The Microchip Technology 24AA00T-I/SN is a 128-bit (16 x 8) serial Electrically Erasable PROM featuring a 2-wire I2C compatible interface. It operates on a single supply voltage ranging from 1.8V to 5.5V and supports clock frequencies of up to 400 kHz. The device utilizes low-power CMOS technology, ensuring typical standby current of 100 nA and read current of 500 µA. It offers data retention exceeding 200 years and endurance of over one million erase/write cycles. The component is housed in an 8-lead SOIC 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 with minimal power consumption
• I2C compatible bidirectional serial interface with noise suppression
• High reliability with extended data retention and write cycle endurance

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'I' designation aligns with the required industrial temperature range for your application environment. Ensure the system design accommodates the 1.8V minimum operating voltage specified for this variant.

Memory IC Selection Notes

Select this component for applications requiring small non-volatile storage with low power constraints. The 1.8V operating range distinguishes it from other variants in the family that may require higher voltages. Verify compatibility with the host controller's I2C bus timing requirements before integration.

Memory IC Part Context

This part belongs to the 24XX00 series of serial EEPROMs, which includes the 24LC00 and 24C00 devices. While sharing similar interfaces and memory organization, the 24AA00 variant is specifically optimized for lower voltage operation starting at 1.8V compared to the 2.5V minimum of the 24LC00.

Memory IC Replacement Considerations

Direct replacements include the 24LC00T-I/SN or 24C00T-I/SN, provided the system voltage meets their respective minimum operating thresholds.
