24FC16H-I/SN

Memory IC Overview

The Microchip Technology 24FC16H-I/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 at supply voltages between 1.7V and 5.5V. The device includes a 16-byte page write buffer and hardware write-protect functionality for the upper half of the array (addresses 400h-7FFh) via the WP pin. Operating within an industrial temperature range of -40°C to +85°C, it utilizes low-power CMOS technology with standby currents as low as 1 μA.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock frequencies reaching 1 MHz
• Provides hardware-based write protection for half of the memory array
• Features Schmitt trigger inputs and noise suppression circuits for reliable data transmission
• Includes a 16-byte page write buffer to optimize write cycle efficiency

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in consumer electronics
• Calibration data storage in sensor modules

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific voltage and speed requirements align with the 24FC16H series specifications. Ensure compatibility with existing I2C bus architectures before procurement. Cross-reference datasheet revision numbers to guarantee accurate electrical characteristics.

Memory IC Selection Notes

Select this component when high-speed I2C communication is required alongside non-volatile storage capabilities. The 24FC16H offers faster performance compared to standard 400 kHz EEPROMs while maintaining low power consumption. Consider the hardware write-protect feature if security against accidental overwrites is necessary for the application design.

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 distinguishes itself through higher clock frequency support. The family provides flexible packaging options including SOIC, MSOP, and TDFN to suit various board space constraints.

Memory IC Replacement Considerations

Direct replacements include other members of the 24XX16H family such as the 24AA16H or 24LC16BH, noting differences in maximum clock frequency and minimum operating voltage. Verify pinout compatibility and software protocol adherence when substituting.
