24AA014H-I/P

Memory IC Overview

The Microchip Technology 24AA014H-I/P 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 supports I²C™ compatible 2-Wire Serial Interface Bus communication with a maximum clock frequency of 400 kHz. The device features low-power CMOS technology, drawing a maximum active current of 400 μA and a standby current of 1 μA. It includes hardware write protection for half the array via the WP pin, a page write buffer for up to 16 bytes, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-pin PDIP package and is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Hardware write protection capability for the upper half of the memory array using the WP pin
• Page write buffer supporting sequential writes of up to 16 bytes
• Schmitt trigger inputs and output slope control for enhanced noise immunity and ground bounce elimination

Memory IC Applications

• Data logging applications requiring non-volatile storage
• Configuration parameter storage in embedded systems
• Device identification and calibration data retention

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple physical packages including SOIC, TSSOP, MSOP, and TDFN. Confirm the temperature grade corresponds to the intended operating environment. Ensure the voltage supply range aligns with the 1.7V minimum specification for the Industrial grade variant. Cross-reference the datasheet revision to confirm interface compatibility.

Memory IC Selection Notes

Select this component when a small, non-volatile memory solution is needed for storing configuration data or logs in space-constrained designs. The 1.7V minimum operating voltage makes it suitable for battery-powered applications where power efficiency is critical. The I²C interface allows for simple connection with minimal microcontroller GPIO usage. Consider the page write buffer size if high-speed sequential writing is required.

Memory IC Part Context

This EEPROM belongs to the 24AA014H/24LC014H family of 1 Kbit serial memories. The 'I' suffix denotes the Industrial temperature grade (-40°C to +85°C), while the 'P' indicates the 8-pin PDIP package. This family shares functional similarities with other sizes in the series but differs in capacity and specific electrical characteristics such as clock speed limits at lower voltages.

Memory IC Replacement Considerations

Direct replacements within the same package and specifications include the 24AA014H-E/P for extended automotive temperature ranges. Other capacities in the 24AAxxH series may be functionally similar but require verification of address mapping and buffer sizes.
