24AA014H-I/SN

Memory IC Overview

The Microchip Technology 24AA014H-I/SN is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 1.7V to 5.5V and utilizes a 2-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz. The device features hardware write protection for half the array, supports page writes up to 16 bytes, and offers high endurance with one million erase/write cycles. It includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Hardware write protection capability for half the memory array via the WP pin
• Page write buffer supporting up to 16 bytes per write cycle
• Schmitt trigger inputs and output slope control for enhanced signal integrity

Memory IC Applications

• Industrial embedded systems requiring non-volatile data storage
• Consumer electronics utilizing low-power microcontrollers
• Automotive applications operating within industrial temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, specifically SOIC-8 for this model. Confirm the temperature grade 'I' aligns with the intended operational environment of -40°C to +85°C. Ensure the voltage range of 1.7V to 5.5V meets system power requirements. Check RoHS compliance status if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this component when a 1 Kbit EEPROM with I2C interface is needed. The 24AA014H variant supports operation down to 1.7V, unlike the 24LC014H which requires a minimum of 2.5V. Consider the SOIC-8 package for surface mount assembly. Verify that the 400 kHz clock speed suffices for the application's data throughput needs.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. These devices are designed for low-power applications and feature a standard 2-wire serial interface. The family includes variants with different voltage ranges and temperature grades, packaged in PDIP, SOIC, TSSOP, MSOP, and TDFN formats.

Memory IC Replacement Considerations

The 24LC014H-I/SN is a functional substitute but requires a minimum supply voltage of 2.5V compared to the 1.7V minimum of the 24AA014H. Other 1 Kbit I2C EEPROMs may require software adjustments due to differences in command sets or timing specifications.
