24AA014HT-I/SN

Memory IC Overview

The Microchip Technology 24AA014HT-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 supports I²C™ compatible 2-wire serial communication with a maximum clock frequency of 400 kHz. The device features hardware write protection for half the array, low-power CMOS technology, and an access time of 900 ns. It is housed in an 8-pin SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array via the WP pin.
• Integrated page write buffer allows efficient storage of up to 16 bytes per transaction.
• Schmitt trigger inputs provide noise suppression and improved signal integrity on the bus.

Memory IC Applications

• Industrial control systems requiring non-volatile data retention
• Consumer electronics utilizing low-voltage operation
• Embedded devices needing compact serial memory solutions

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape-and-reel packaging when sourcing components. Confirm the 'I' designation matches the required industrial temperature range specifications for your specific application environment before finalizing procurement orders.

Memory IC Selection Notes

Select this component for applications requiring robust noise immunity and flexible addressing capabilities. The inclusion of Schmitt triggers makes it suitable for noisy environments. Ensure the system design accommodates the hardware write-protect functionality if partial array security is necessary.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other members of the series but is distinguished by its specific voltage range and industrial temperature rating.

Memory IC Replacement Considerations

Compatible substitutes include the 24AA014HT-E/SN for extended temperature requirements and the 24LC014HT-I/SN for higher speed operations at elevated voltages.

Memory IC FAQ

How does the hardware write protection function?

Tying the WP pin to VCC enables write protection for the upper half of the array (addresses 40h-7Fh), preventing accidental modification of critical data.

What is the purpose of the page write buffer?

The buffer allows the master to transmit up to 16 bytes of data sequentially, which are then written to memory automatically upon receiving a Stop condition.
