24AA00-I/SN

Memory IC Overview

The Microchip Technology 24AA00-I/SN is a 128-bit (16 x 8) Electrically Erasable PROM memory device 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 component utilizes low-power CMOS technology with typical read current of 500 µA and standby current of 100 nA. It offers more than 1 million erase/write cycles, data retention exceeding 200 years, and ESD protection greater than 4000V. The industrial temperature grade (-I) ensures operation between -40°C and +85°C within an 8-lead SOIC package.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication protocol with Schmitt trigger inputs for noise suppression
• Features self-timed erase/write cycles with acknowledge polling capability to maximize bus throughput
• Includes output slope control logic designed to eliminate ground bounce during switching operations
• Provides hardware data protection through high ESD tolerance and robust data retention characteristics

Memory IC Applications

• Storage of calibration values in electronic systems
• Retention of unique identification numbers for device tracking
• Recording manufacturing information and configuration parameters
• Small-scale non-volatile data logging in low-power embedded devices

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range of -40°C to +85°C. Confirm the '/SN' designation corresponds to the 8-lead Small Outline Integrated Circuit package with a 3.90 mm body width. Ensure the ordering code matches the required voltage operating range for the 24AA00 variant, which supports operation down to 1.8V. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Memory IC Selection Notes

Select this component when a minimal 128-bit EEPROM capacity is sufficient for storing static system parameters or identifiers. The 24AA00 variant is appropriate for designs requiring operation at supply voltages as low as 1.8V, distinguishing it from the 2.5V minimum 24LC00 series. Consider the 400 kHz clock speed for applications requiring faster bus transactions compared to standard 100 kHz limits. The 8-pin SOIC package facilitates surface-mount assembly in compact PCB layouts.

Memory IC Part Context

This device belongs to the Microchip 24XX00 family of serial EEPROMs, which includes the 24LC00 and 24C00 variants. These parts share identical pinouts and functional interfaces but differ in supply voltage requirements and temperature grades. The 24AA00 specifically targets low-voltage applications, while the 24C00 requires higher supply levels. All members of this family utilize the same 2-wire serial protocol and offer comparable endurance and retention specifications.

Memory IC Replacement Considerations

Direct substitutes include the 24LC00-I/SN and 24C00-I/SN, provided the system supply voltage meets their respective minimum thresholds of 2.5V and 4.5V. Verify that any replacement maintains the 8-lead SOIC package dimensions and I²C interface compatibility. Ensure the alternative part number supports the required industrial temperature range if operating conditions exceed commercial limits.
