24C02C/SN

Memory IC Overview

The Microchip Technology 24C02C/SN is a 2-Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single 5.0V supply with a voltage range of 4.5V to 5.5V. The device utilizes a 2-Wire I2C compatible interface supporting a maximum clock frequency of 400 kHz. Key electrical parameters include a typical access time of 900 ns, a maximum active read current of 3 mA, and a standby current of 5 µA. It features a data retention period of 200 years and supports over one million write cycles. The component is housed in an 8-SOIC package.

Memory IC Feature Summary

• Supports high-speed 400 kHz I2C communication for efficient data transfer
• Provides robust non-volatile storage with extended 200-year data retention
• Includes hardware write-protect capability to prevent accidental data modification

Memory IC Applications

• Storage of configuration parameters and calibration data in embedded systems
• Recording user settings that require persistence across power cycles
• Storing unique device identifiers such as serial numbers or MAC addresses

Memory IC Procurement Notes

Verify the specific suffix 'SN' confirms the SOIC-8 surface mount package and industrial temperature rating. Confirm the absence of additional letters indicating tape-and-reel packaging if tube delivery is required. Ensure the ordering part number matches the exact voltage and speed specifications needed for the target application design.

Memory IC Selection Notes

Select this component when a standard 5V logic interface is required alongside fast 400 kHz I2C performance. It is suitable for designs needing reliable non-volatile storage in industrial environments. Consider alternative packages like PDIP or MSOP if board space constraints differ from the SOIC footprint requirements.

Memory IC Part Context

This EEPROM belongs to the widely adopted 24C02 family, designed for general-purpose data storage in microcontroller-based systems. The 24C02C variant specifically denotes the enhanced version supporting faster bus speeds compared to older 100 kHz models. It serves as a standard solution for small-scale persistent memory needs in consumer and industrial electronics.

Memory IC Replacement Considerations

The AT24C02C/SN is a direct functional equivalent from Microchip. Other manufacturers offer pin-compatible alternatives within the same capacity and interface specifications.
