24AA01HT-I/ST

Memory IC Overview

The Microchip Technology 24AA01HT-I/ST is a 1 Kbit (128 x 8) Serial Electrically Erasable PROM featuring a 2-Wire I²C compatible interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write-protect functionality for the upper half of the memory array, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Hardware write-protect capability for half-array protection
• I²C compatible bidirectional serial data transfer
• Schmitt trigger inputs for enhanced noise suppression
• Output slope control to minimize ground bounce

Memory IC Applications

• Low-power consumer electronics requiring non-volatile storage
• Industrial systems with noisy bus environments
• Battery-operated devices utilizing low standby current
• Automotive applications operating in extended temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape and reel packaging and 'ST' indicates the SOIC package type. Confirm the 'I' suffix matches the required industrial temperature range specifications. Ensure the component meets RoHS compliance requirements for your specific manufacturing process.

Memory IC Selection Notes

Select this part when a small 1 Kbit EEPROM capacity is sufficient for application needs. Choose this model over variants with higher densities if board space is limited. Consider the 1.7V minimum operating voltage for compatibility with low-voltage microcontrollers. Verify that the 400 kHz maximum clock frequency aligns with system timing requirements.

Memory IC Part Context

This component belongs to the 24AA01H/24LC01BH family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. These devices are designed for advanced low-power applications and share common interface protocols within the broader 24XX series lineup. The family offers various package options including SOIC, TSSOP, and SOT-23.

Memory IC Replacement Considerations

Direct replacements include the 24AA01H-I/SN or 24LC01BH-I/SN from the same datasheet. Verify voltage range compatibility as 24LC01BH variants require a minimum of 2.5V. Check package pinout alignment between SOIC variants before substitution.
