24AA014HT-I/MS

Memory IC Overview

The Microchip Technology 24AA014HT-I/MS 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 clock frequencies up to 400 kHz. The device features hardware write protection for half the array, low-power CMOS technology with maximum active current of 400 μA and standby current of 1 μA, and data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write protection capability for half the memory array via the WP pin
• Low-power CMOS design supporting operation down to 1.7V
• I²C™ compatible 2-Wire Serial Interface Bus with Schmitt trigger inputs
• Page write buffer allowing writes of up to 16 bytes

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Embedded systems needing compact serial EEPROM solutions

Memory IC Procurement Notes

Verify the specific suffix 'HT' indicates tape and reel packaging when ordering. Confirm the 'I' temperature grade matches industrial requirements (-40°C to +85°C). Ensure the MSOP-8 package dimensions align with your PCB footprint constraints. Cross-reference the datasheet revision date to confirm electrical characteristics have not changed.

Memory IC Selection Notes

Select this component for applications requiring robust noise immunity due to Schmitt trigger inputs. It is suitable for designs needing hardware-level write protection without software overhead. Consider the 400 kHz speed limit if higher bus speeds are required, as the LC variant offers 1 MHz operation but requires a minimum 2.5V supply.

Memory IC Part Context

This part belongs to the 24AA014H series of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC014H but differs in operating voltage range and maximum clock frequency specifications. The MSOP package provides a compact surface-mount solution for space-constrained designs.

Memory IC Replacement Considerations

The 24AA014H-I/MS is a direct pin-compatible alternative without the HT suffix. For higher speed requirements, the 24LC014H series offers 1 MHz compatibility but requires a minimum 2.5V supply voltage.
