24AA00/ST

Memory IC Overview

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

Memory IC Feature Summary

• Low-voltage operation down to 1.8V with minimal power consumption
• I2C compatible bidirectional 2-wire serial data transfer
• Schmitt trigger inputs provide enhanced noise spike suppression
• Self-timed erase/write cycles with acknowledge polling capability

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'ST' against official Microchip documentation to confirm package type and temperature range. Ensure the ordering code matches the required industrial specifications. Confirm RoHS compliance status through the manufacturer's latest product compliance reports before finalizing procurement orders.

Memory IC Selection Notes

Select this component when small EEPROM capacity is sufficient for non-volatile data storage. The 1.8V minimum operating voltage makes it suitable for low-power applications. Verify that the system bus timing requirements align with the specified 100 kHz or 400 kHz clock compatibility limits.

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 interface and functional characteristics, these variants differ in their minimum operating voltage thresholds and available temperature ranges. The 24AA00 specifically supports the lowest voltage range within this group.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC00 and 24C00 series devices. Verify voltage range compatibility, as 24LC00 requires a minimum of 2.5V and 24C00 requires 4.5V. Ensure pinout and package dimensions match the existing design constraints.
