24C02CT/SN

Memory IC Overview

The Microchip Technology 24C02CT/SN is a 2-kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM) integrated circuit. It utilizes an I2C-compatible two-wire serial interface for data communication, supporting clock frequencies up to 400 kHz. The device operates within a supply voltage range of 4.5V to 5.5V and features a fast access time of 3.5 µs. It is housed in an 8-SOIC surface-mount package with a width of 3.90 mm. The component is designed for industrial applications with an operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock rates up to 400 kHz
• Provides non-volatile data storage with 2-kbit capacity organized as 256 words by 8 bits
• Features low-power CMOS technology for efficient operation

Memory IC Applications

• Data logging systems requiring persistent storage
• Configuration parameter retention in embedded controllers
• Calibration data storage for sensor modules

Memory IC Procurement Notes

Verify the specific suffix 'CT' indicates tape-and-reel packaging when sourcing components. Confirm that the 400 kHz speed grade matches system timing requirements, distinguishing it from the 100 kHz variant. Ensure the 8-SOIC footprint aligns with PCB layout specifications before procurement.

Memory IC Selection Notes

Select this part for designs requiring standard 5V logic levels and moderate data transfer speeds. The 400 kHz interface suits most general-purpose microcontroller applications. Consider the -E suffix if extended temperature ranges are necessary, or alternative packages like MSOP if space constraints dictate smaller form factors.

Memory IC Part Context

This component belongs to the 24C02C family of serial EEPROMs manufactured by Microchip Technology. These devices are widely used in consumer electronics and industrial equipment for storing small amounts of critical data that must persist without power. The SOIC package offers a balance between ease of assembly and compact size.

Memory IC Replacement Considerations

The 24C02CT-E/SN serves as a verified equivalent with identical electrical characteristics but supports an extended temperature range of -40°C to 125°C. Other pin-compatible alternatives may exist from different manufacturers, but interface compatibility and voltage levels must be validated.
