24AA01HT-I/SN

Memory IC Overview

The Microchip Technology 24AA01HT-I/SN is a 1 Kbit (128 x 8) serial EEPROM featuring an I²C-compatible 2-wire 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 supports page writes of up to 8 bytes and includes hardware write protection for the upper half of the memory array via the WP pin. It utilizes low-power CMOS technology, offering standby current as low as 1 μA and read current of 1 mA. The component is housed in an 8-lead SOIC package and is rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array when the WP pin is tied high.
• Schmitt trigger inputs and output slope control provide noise suppression and eliminate ground bounce during operation.
• Supports acknowledge polling to maximize bus throughput by allowing the master to detect when internal write cycles are complete.

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial control applications operating within the specified temperature range
• Battery-powered devices utilizing low standby current modes

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape and reel packaging requirements for your assembly line. Confirm the 'I' suffix matches the required industrial temperature grade of -40°C to +85°C. Ensure the 'SN' designation aligns with the specific 8-lead SOIC package dimensions needed for your PCB footprint. Cross-reference the manufacturer part number against the latest datasheet revision to confirm electrical characteristics remain unchanged.

Memory IC Selection Notes

Select this component if your design requires a 1 Kbit capacity with a standard I²C interface. It is suitable for applications needing hardware-level write protection for critical data segments. Consider this part for space-constrained designs due to its compact surface-mount package. Ensure the system voltage remains above 1.7V to guarantee proper functionality across all operating conditions.

Memory IC Part Context

This device belongs to the 24AA01H family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24LC01BH but differs in minimum operating voltage specifications. The family is designed for general-purpose non-volatile memory applications where low power consumption and reliable data retention are primary requirements.

Memory IC Replacement Considerations

The 24AA01H serves as the base model for this variant. Verify compatibility with other 24AA01 series parts if package or packaging format differences exist.
