24AA00/S

Memory IC Overview

The Microchip Technology 24AA00/S is a 128-bit Electrically Erasable PROM memory organized as 16 x 8. It features a 2-wire serial interface compatible with the I2C bus, supporting clock frequencies up to 400 kHz. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V. It utilizes low-power CMOS technology, ensuring typical read current of 500 µA and standby current of 100 nA. The component includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Supports bidirectional data transfer via a 2-wire serial interface compatible with I2C protocols.
• Features Schmitt trigger inputs and filter circuits to suppress noise spikes on the SCL and SDA lines.
• Includes an internal address pointer that increments automatically during sequential read operations.
• Provides acknowledge polling capability to determine when an internal write cycle is complete.

Memory IC Applications

• Storage of calibration values in electronic systems
• Retention of identification numbers for device tracking
• Recording manufacturing information during production

Memory IC Procurement Notes

Verify the specific package suffix against official documentation to confirm physical dimensions and pin configuration. Ensure the operating voltage range aligns with the system's power supply requirements. Confirm temperature grade specifications match the intended environmental conditions. Cross-reference the datasheet revision to ensure compatibility with existing design constraints.

Memory IC Selection Notes

Select this component for applications requiring minimal non-volatile storage capacity with low power consumption. The 1.8 V minimum operating voltage makes it suitable for battery-powered devices. Consider the available package options such as PDIP, SOIC, TSSOP, DFN, and SOT-23 based on board space constraints. Verify that the I2C bus speed requirements do not exceed the supported maximum frequency.

Memory IC Part Context

This device belongs to the 24XX00 family of serial EEPROMs, which also includes the 24LC00 and 24C00 variants. While sharing similar functional characteristics and interface protocols, these variants differ primarily in their specified operating voltage ranges and temperature grades. The 24AA00 is specifically designed for lower voltage operation starting at 1.8 V.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC00 and 24C00. Verify voltage compatibility as 24LC00 requires a minimum of 2.5 V and 24C00 requires 4.5 V. Ensure package type matches or is adaptable. Check temperature range specifications if operating outside standard industrial limits.
