24AA01T-I/MS

Memory IC Overview

The Microchip Technology 24AA01T-I/MS is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes an 8-lead MSOP surface-mount package and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard 2-wire serial bus protocol
• Includes hardware write protection controlled by the WP pin
• Features Schmitt trigger inputs for noise suppression
• Provides an 8-byte page write buffer for efficient data storage

Memory IC Applications

• Low-power consumer electronics requiring non-volatile data retention
• Industrial control systems operating within specified temperature limits
• Portable devices utilizing low-voltage power supplies
• Data acquisition systems needing small-scale parameter storage

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type and Industrial temperature grade. Confirm RoHS compliance status matches current manufacturing standards. Ensure the supplier provides valid traceability codes consistent with Microchip marking requirements for this component variant.

Memory IC Selection Notes

Select this component when a 1 Kbit EEPROM capacity is required with I2C connectivity. It is suitable for designs needing operation down to 1.7V. Consider the MSOP package dimensions for PCB layout constraints. Verify that the 400 kHz clock speed meets system timing requirements.

Memory IC Part Context

This part belongs to the 24XX01 family of serial EEPROMs, which includes variants like the 24LC01B and 24FC01. These devices share similar functional architectures but differ in voltage ranges and clock speeds. The 24AA01 series specifically targets applications requiring wide voltage operation starting at 1.7V.

Memory IC Replacement Considerations

Direct substitutes include other 24AA01 variants with different packages such as SOIC or TDFN. Cross-family replacements like the 24LC01B require checking voltage compatibility as it starts at 2.5V. Ensure any replacement maintains the same memory organization and interface protocol.
