24FC16-E/SN

Memory IC Overview

The Microchip Technology 24FC16-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 and supports clock frequencies up to 1 MHz at supply voltages between 1.7V and 5.5V. The device operates within an extended temperature range of -40°C to +125°C and includes hardware write protection, Schmitt trigger inputs for noise suppression, and output slope control.

Memory IC Feature Summary

• Supports high-speed serial data transmission with a maximum clock frequency of 1 MHz
• Includes a 16-byte page write buffer to optimize write operations
• Features hardware write-protect capability via the WP pin to secure memory arrays
• Incorporates Schmitt trigger inputs and filter circuits to suppress bus noise

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability
• Configuration storage for embedded systems operating on low-voltage power supplies
• Parameter retention in automotive electronic modules subject to harsh thermal conditions

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage supply range aligns with the system design, as this variant supports operation down to 1.7V. Ensure compatibility with the host controller's I²C bus timing requirements before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when applications demand high-speed serial communication alongside wide voltage tolerance. The extended temperature rating makes it suitable for demanding environments where standard industrial grades are insufficient. Consider the 16-byte page buffer efficiency for frequent small data updates compared to byte-write alternatives.

Memory IC Part Context

This EEPROM belongs to the 24XX16 family, which shares common architectural features across different speed and voltage variants. While other members like the 24LC16B operate at lower speeds or higher minimum voltages, the 24FC16 specifically targets high-performance needs within the same physical footprint and protocol framework.

Memory IC Replacement Considerations

Direct substitutes include the 24AA16 for lower-speed requirements or the 24LC16B if the system voltage does not support 1.7V operation. Verify that any replacement maintains the 8-pin SOIC package dimensions and I²C addressing scheme to ensure board-level compatibility.
