24C01C-E/ST

Memory IC Overview

The Microchip Technology 24C01C-E/ST is a 1-kbit (128 x 8) serial Electrically Erasable PROM featuring an I2C-compatible two-wire interface. It operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 400 kHz. The device utilizes advanced CMOS technology for low power consumption, offering a maximum access time of 3.5 µs. It is housed in an 8-pin SOIC package and is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock frequencies up to 400 kHz
• Provides hardware write protection capabilities for data security
• Features self-timed write cycles with automatic erase-before-write functionality
• Ensures long-term data retention exceeding 200 years

Memory IC Applications

• Industrial control systems requiring non-volatile parameter storage
• Consumer electronics utilizing I2C bus architectures
• Automotive modules operating within extended temperature environments
• Embedded systems needing secure configuration data retention

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the industrial temperature grade (-40°C to +85°C) and 'ST' denotes the SOIC-8 package. Confirm that the 4.5 V minimum supply voltage aligns with your system's power rails, as this variant differs from lower-voltage counterparts. Ensure compatibility with your I2C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when a 1-kbit capacity and 400 kHz I2C speed are required within a 5 V logic environment. It is suitable for applications demanding robust data retention and hardware write protection. Consider alternative variants if your system operates below 4.5 V or requires automotive AEC-Q100 qualification, as this specific part number targets industrial specifications.

Memory IC Part Context

This EEPROM belongs to the Microchip 24C01A/02A/04A family of serial memory devices. These components share common architectural features such as the two-wire serial interface and CMOS technology. The 24C01C-E/ST specifically addresses industrial-grade requirements, distinguishing itself from commercial variants through its extended temperature rating and specific voltage operating window.

Memory IC Replacement Considerations

The 24C01B-E/ST is a compatible alternative within the same package, though it typically supports a wider voltage range starting at 2.5 V. Verify that the target system can accommodate the 4.5 V minimum requirement of the 24C01C-E/ST. Other family members like the 24C02A offer higher density but may require software adjustments for address mapping.
