24FC16HT-E/SN

Memory IC Overview

The Microchip Technology 24FC16HT-E/SN is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 1 MHz across a supply voltage range of 1.7V to 5.5V. The device operates within an extended temperature range of -40°C to +125°C and utilizes low-power CMOS technology. It includes a hardware write-protect function for half the array and supports page writes of up to 16 bytes.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Low-power operation with standby current as low as 3 μA in extended temperature conditions
• Integrated Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Data logging in industrial environments requiring high-temperature stability
• Configuration storage for embedded systems operating at low voltages
• Parameter retention in automotive electronics subject to AEC-Q100 standards

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the 8-Lead SOIC package and 'E' indicates the Extended temperature grade (-40°C to +125°C). Confirm the 'T' suffix denotes tape-and-reel packaging if required by automated assembly processes. Ensure the specific revision matches the datasheet DS20002118B for accurate electrical characteristics.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is needed with I2C compatibility and robust performance in high-temperature applications. The 24FC series offers higher speed (1 MHz) compared to standard 400 kHz variants. Verify that the system voltage remains above 1.7V to ensure proper functionality across the full operating range.

Memory IC Part Context

This part belongs to the 24XX16H family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA16H and 24LC16BH but is distinguished by its ability to operate down to 1.7V and support 1 MHz clock speeds. The family provides non-volatile memory solutions for various consumer and industrial applications.

Memory IC Replacement Considerations

Direct substitutes include other parts within the 24FC16H family with different package options, such as 24FC16HT-E/OT for SOT-23-5 or 24FC16HT-E/MS for MSOP. Cross-family replacements like 24LC16BH are available but limited to 400 kHz operation and a minimum 2.5V supply.
