24C01CT-E/OT

Memory IC Overview

The Microchip Technology 24C01CT-E/OT is a 1-kbit (128 x 8) serial Electrically Erasable PROM featuring an I2C-compatible two-wire serial interface. It operates within a supply voltage range of 1.7 V to 5.5 V and supports clock frequencies up to 1 MHz. The device utilizes an SOT-23-5 surface-mount package and ensures data retention for over 200 years. It functions reliably across an extended industrial temperature range from -40°C to +125°C, providing non-volatile storage with low power consumption.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock frequencies up to 1 MHz
• Operates on a wide single-supply voltage range from 1.7 V to 5.5 V
• Provides long-term data retention exceeding 200 years
• Engineered for reliable operation in extreme industrial temperatures

Memory IC Applications

• Industrial control systems requiring robust memory in harsh environments
• Consumer electronics utilizing low-voltage power supplies
• Automotive embedded applications needing extended temperature tolerance
• Portable devices where compact SOT-23-5 packaging is critical

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +125°C) and 'OT' denotes the SOT-23-5 tape-and-reel packaging configuration. Confirm that the 1 MHz clock speed requirement aligns with system bus capabilities. Ensure voltage levels remain within the 1.7 V to 5.5 V operational window during all phases of operation to maintain data integrity and prevent access violations.

Memory IC Selection Notes

Select this component when a balance between high-speed I2C performance and ultra-low voltage operation is required. The SOT-23-5 package offers space efficiency for dense PCB layouts. Consider the extended temperature rating for applications exposed to thermal stress. Compare against standard commercial grades if operating conditions remain within typical ambient ranges to optimize cost.

Memory IC Part Context

This part belongs to the 24FC01 family of serial EEPROMs, which are designed for general-purpose non-volatile memory applications. The family shares common I2C protocol compatibility but varies in package options and temperature ratings. The 24C01CT variant specifically targets high-volume manufacturing through reel packaging while maintaining the electrical characteristics of the broader series.

Memory IC Replacement Considerations

Direct substitutes include other 24FC01 variants with compatible pinouts, such as 24FC01T-E/MC or 24FC01-E/MS, provided the package type matches the design constraints. Verify that alternative packages support the same 1.7 V to 5.5 V voltage range and 1 MHz clock speed without requiring schematic modifications.
