24AA014H-I/ST

Memory IC Overview

The Microchip Technology 24AA014H-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 with a maximum clock frequency of 400 kHz in the Industrial temperature grade (-40°C to +85°C). The device includes hardware write protection for half the array, supports page writes of up to 16 bytes, and offers high endurance with one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write protection capability for the upper half of the memory array via the WP pin
• Integrated Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Self-timed write cycle with automatic erase-write functionality and acknowledge polling support
• Supports multiple device addressing allowing up to eight units on a single bus

Memory IC Applications

• Low-power embedded systems requiring non-volatile data storage
• Industrial control applications operating within extended temperature ranges
• Consumer electronics utilizing I²C serial communication protocols
• Battery-powered devices benefiting from low standby current consumption

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the ST package type, which denotes an 8-lead Thin Shrink Small Outline Package (SOIC). Confirm the 'I' suffix indicates the Industrial temperature range specification. Ensure compatibility with the required supply voltage levels and bus speed requirements before integration into the design.

Memory IC Selection Notes

Select this component when a small capacity EEPROM with hardware write protection is required. The 24AA014H variant supports operation down to 1.7V, making it suitable for lower voltage applications compared to the 24LC014H. Consider the page write buffer size and bus addressing limits when designing the system architecture.

Memory IC Part Context

This device belongs to the 24AA014H/24LC014H family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other members of the 24-series but is distinguished by its specific voltage range and industrial temperature rating. The part utilizes standard I²C protocol for data transfer.

Memory IC Replacement Considerations

The 24LC014H serves as a functional alternative within the same datasheet, though it requires a minimum supply voltage of 2.5V instead of 1.7V. Verify package compatibility and voltage specifications when substituting.
