24C01CT-E/MC

Memory IC Overview

The Microchip Technology 24C01CT-E/MC 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 offers a typical access time of 900 ns. Packaged in an 8-lead DFN (2x3 mm) format, it supports surface mount installation and functions across an industrial temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed I2C communication at up to 400 kHz for efficient data transfer
• Provides robust data retention exceeding 200 years with over one million erase/write cycles
• Includes hardware write protection capabilities to prevent accidental data modification
• Features Schmitt trigger inputs and output slope control for noise suppression and signal integrity

Memory IC Applications

• Industrial control systems requiring reliable non-volatile storage
• Consumer electronics needing compact memory solutions
• Automotive applications operating in extreme temperature environments
• Smart metering devices for secure data logging

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +125°C) as per official datasheets. Confirm the 'MC' package code corresponds to the 8-lead DFN form factor. Ensure compatibility with 4.5V to 5.5V power rails before integration. Check RoHS compliance status for environmental regulations. Validate lead-free specifications against project requirements.

Memory IC Selection Notes

Select this component when a small footprint DFN package is required for space-constrained designs. Choose this part if operation above 85°C is necessary, distinguishing it from commercial grade variants. Consider the 400 kHz speed limit; higher speeds require alternative models like the 24FC series. Verify voltage constraints, as lower voltage options are available in other product lines.

Memory IC Part Context

This EEPROM belongs to the 24C01C family of serial memories from Microchip Technology. It shares architectural similarities with the 24C02 and 24C04 but offers distinct 1-kbit capacity. The CT suffix denotes tape and reel packaging, facilitating automated assembly processes compared to tube-packaged equivalents.

Memory IC Replacement Considerations

The 24C01CT-I/MC serves as a direct functional substitute with identical electrical characteristics but a reduced industrial temperature range (-40°C to +85°C). Other 24C01 variants may differ in package type or voltage specifications.
