24C02C-I/SN

Memory IC Overview

The Microchip Technology 24C02C-I/SN is a 2-Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single 5.0V supply within the 4.5V to 5.5V range and utilizes an I2C-compatible two-wire serial interface supporting clock frequencies up to 400 kHz. The device features a typical write cycle time of 1 ms, access times of 900 ns, and standby current of 5 μA maximum. It guarantees over one million erase/write cycles and data retention exceeding 200 years. The component is housed in an 8-lead SOIC package and supports industrial temperature ranges.

Memory IC Feature Summary

• Supports high-speed 400 kHz I2C communication alongside standard 100 kHz compatibility for flexible system integration.
• Includes hardware write-protect functionality for the upper half of the memory array to prevent unauthorized data modification.
• Features Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce during operation.

Memory IC Applications

• Industrial control systems requiring reliable non-volatile data storage
• Consumer electronics utilizing I2C bus architectures
• Automotive embedded applications needing robust data retention

Memory IC Procurement Notes

Verify the specific suffix 'I/SN' against official Microchip documentation to confirm the industrial temperature grade and SOIC-8 package configuration. Ensure that the required operating voltage aligns with the specified 4.5V to 5.5V range. Confirm that the target application does not require the wider voltage range found in other variants like the 24FC02 series. Cross-reference the datasheet revision date to ensure compliance with current RoHS standards.

Memory IC Selection Notes

Select this component when a dedicated 5.0V supply is available and high-speed 400 kHz I2C performance is required. It is suitable for designs needing hardware write protection for critical data segments. Consider alternative packages such as TSSOP or DFN if space constraints differ from the SOIC footprint. Verify that the 256-byte capacity meets the storage requirements without necessitating larger memory arrays.

Memory IC Part Context

This part belongs to the 24C02C family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA02 and 24LC02B series but is optimized for 5.0V operation. The 'I' designation indicates an extended industrial temperature range, while 'SN' specifies the surface-mount SOIC package type. This family is widely used in general-purpose memory applications.

Memory IC Replacement Considerations

The 24LC02C-I/SN serves as a compatible alternative with similar specifications but may support lower voltage operations. The 24AA02C-I/SN offers comparable performance with potentially different electrical characteristics. Verify pinout compatibility and voltage tolerances before substituting these parts in existing designs.
