24AA014H-I/MS

Memory IC Overview

The Microchip Technology 24AA014H-I/MS 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 utilizes Low-Power CMOS technology, drawing a maximum of 400 μA during active operation and 1 μA in standby mode. It includes hardware write protection for half the array via the WP pin, supports page writes up to 16 bytes, and offers over 1 million erase/write cycles with data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write protection capability for half the memory array using the WP pin
• Page write buffer supporting up to 16 bytes per cycle
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Self-timed write cycle with automatic erase-write functionality

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial applications operating within -40°C to +85°C environments
• I²C bus expansion for microcontroller-based designs
• Portable devices utilizing low-power standby modes

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'MS' indicates the 8-lead MSOP package. Confirm the specific part number matches the datasheet DS22077B requirements for the 24AA014H series. Ensure compatibility with the 1.7V to 5.5V supply voltage range specified for this variant.

Memory IC Selection Notes

Select this component when an I²C serial EEPROM with hardware write protection is required. The 24AA014H variant supports operation down to 1.7V, suitable for low-voltage logic levels. Consider the 8-pin MSOP package for space-constrained surface-mount designs. Verify that the 400 kHz clock speed meets system timing requirements.

Memory IC Part Context

This component belongs to the 24AA014H/24LC014H family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. These devices are designed for use in applications requiring reliable non-volatile storage with standard I²C communication protocols. The family includes variants optimized for different voltage ranges and temperature grades.

Memory IC Replacement Considerations

The 24LC014H serves as a functional alternative within the same family, though it requires a minimum supply voltage of 2.5V compared to the 1.7V minimum of the 24AA014H. Both share identical pinouts and memory organization.
