24FC02-E/SN

Memory IC Overview

The Microchip Technology 24FC02-E/SN is a 2-Kbit (256 x 8) serial EEPROM featuring an I²C interface with a maximum clock frequency of 1 MHz. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports data retention exceeding 200 years. The device includes hardware write protection, Schmitt trigger inputs for noise suppression, and output slope control. It is available in an 8-lead SOIC package and functions within an extended temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication
• Includes hardware write-protect capability via the WP pin
• Features Schmitt trigger inputs for enhanced noise immunity
• Provides low-power operation with standby current as low as 3 µA

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for embedded controllers
• Industrial equipment operating in noisy environments
• Automotive electronic modules

Memory IC Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'E' suffix indicates Extended temperature range (-40°C to +125°C), while 'I' denotes Industrial range. The '/SN' suffix specifies the 8-lead SOIC package. Confirm voltage requirements align with the 1.7V to 5.5V operational range before procurement.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I²C access is necessary compared to standard 400 kHz devices. Ensure the application requires the extended temperature rating provided by the 'E' suffix. Verify that the 8-pin SOIC footprint fits the PCB layout constraints. Consider the hardware write-protect feature if system security against accidental writes is a priority.

Memory IC Part Context

This part belongs to the 24XX02 family of serial EEPROMs, which also includes the 24AA02 and 24LC02B variants. While sharing similar memory organization and interface protocols, the 24FC02 distinguishes itself through its support for 1 MHz clock speeds and lower minimum operating voltage of 1.7V.

Memory IC Replacement Considerations

The 24FC02-I/SN serves as a functional substitute with identical electrical characteristics but limited to the Industrial temperature range (-40°C to +85°C). Other 24XX02 family members like the 24LC02B operate at lower speeds (400 kHz) and higher minimum voltages (2.5V).
