24C01CT/SN

Memory IC Overview

The Microchip Technology 24C01CT/SN is a 1-kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It features an I2C-compatible two-wire serial interface with a maximum clock frequency of 400 kHz. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in an 8-SOIC package. Key electrical specifications include a typical access time of 900 ns, a write cycle time of 1 ms, and a maximum operating current of 3 mA.

Memory IC Feature Summary

• Supports high-speed 400 kHz I2C communication alongside standard 100 kHz mode compatibility
• Provides non-volatile data storage with over one million erase/write cycles
• Includes hardware write protection for the entire memory array
• Features Schmitt trigger inputs to suppress noise on serial data lines

Memory IC Applications

• Data logging systems requiring persistent storage of sensor readings
• Configuration parameter storage in industrial control devices
• Calibration data retention for electronic measurement instruments
• Device identification and security code storage in embedded systems

Memory IC Procurement Notes

Verify the specific suffix 'CT' indicates tape-and-reel packaging when ordering. Confirm that the required operating voltage aligns with the 4.5 V minimum specification, as this variant does not support lower voltage ranges found in other product families. Ensure the design accommodates the 8-SOIC footprint dimensions and thermal requirements for surface-mount assembly processes.

Memory IC Selection Notes

Select this component when a 400 kHz I2C speed is required within a 5 V logic environment. It serves as a direct replacement for the 24C01T-I/SN if higher bus speeds are needed compared to the standard 100 kHz variants. Consider the SOIC-8 package constraints and verify that the system power supply remains stable above 4.5 V during all operational states to ensure reliable write cycles.

Memory IC Part Context

This part belongs to the Microchip 24C01C series of 1-kbit EEPROMs. It shares architectural similarities with the 24C01T-I/SN but offers faster bus performance. The series is designed for applications needing small, reliable non-volatile memory in compact packages. It complements larger capacity devices like the 24C02 or 24C04 in multi-memory designs.

Memory IC Replacement Considerations

The 24C01T-I/SN is a confirmed substitute offering identical memory organization but with a slower 100 kHz clock limit. Other 24C01C family members in different packages may require pinout verification. Cross-reference datasheets to confirm voltage tolerances and package dimensions before substituting.
