24AA08HT-I/MS

Memory IC Overview

The Microchip Technology 24AA08HT-I/MS is an 8 Kbit Electrically Erasable PROM organized as four blocks of 256 x 8-bit memory. It features a 2-wire serial interface compatible with I2C™, supporting clock frequencies up to 400 kHz for VCC between 2.5V and 5.5V, and 100 kHz for VCC below 2.5V. The device operates on a single supply ranging from 1.7V to 5.5V. It includes hardware write-protect functionality for the upper half of the array (addresses 200h-3FFh) via the WP pin. The component utilizes low-power CMOS technology with maximum read current of 1 mA and standby current of 1 µA. It supports page writes of up to 16 bytes and offers data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write-protect capability for half-array protection
• Low-power operation down to 1.7V with minimal active and standby currents
• Integrated Schmitt trigger inputs for enhanced noise suppression

Memory IC Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Parameter storage in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging rather than tube packaging when reviewing distributor listings. Confirm the 'I' temperature grade matches the required -40°C to +85°C operational range. Ensure the MSOP package type aligns with the PCB footprint design specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component for designs requiring low-voltage operation starting at 1.7V. The MSOP package is suitable for space-constrained surface-mount applications. Consider the hardware write-protect feature if specific memory regions require permanent protection against accidental modification during normal operation cycles.

Memory IC Part Context

This part belongs to the 24AA08H series of 8 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC08BH but differs in minimum operating voltage requirements. The device is designed for general-purpose non-volatile memory applications where power efficiency and reliable data retention are critical factors.

Memory IC Replacement Considerations

Direct replacements include other 24AA08H variants with different package options such as PDIP or SOIC. Cross-reference with 24LC08BH devices only if the system voltage remains above 2.5V, noting the difference in minimum operating voltage specifications.
