24FC16-I/SN

Memory IC Overview

The Microchip Technology 24FC16-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 across the full voltage range of 1.7V to 5.5V. The device utilizes low-power CMOS technology, ensuring standby current remains at or below 1 μA and active read current does not exceed 1 mA. It includes a 16-byte page write buffer and operates within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed serial communication with clock frequencies reaching 1 MHz
• Enables hardware-based write protection via the WP pin for data security
• Incorporates Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce
• Features self-timed erase/write cycles with automatic timing control

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in battery-powered devices
• 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 24FC16 series specifications rather than other variants in the family. Ensure compatibility with the target system's I2C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when high-speed 1 MHz operation is required at supply voltages as low as 1.7V. It is suitable for applications needing robust noise immunity through Schmitt triggers and hardware write protection. Compare against 24LC16B if lower power consumption at higher voltages is prioritized over maximum clock speed.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA16 and 24LC16B but offers distinct performance characteristics regarding voltage ranges and clock speeds. The 'I' designation indicates industrial temperature rating, while 'SN' specifies the 8-lead SOIC package.

Memory IC Replacement Considerations

Direct substitutes include the 24AA16-I/SN and 24LC16B-I/SN, provided the application can accommodate their respective clock frequency limitations and voltage operating ranges.
