24C01CT-I/SN

Memory IC Overview

The Microchip Technology 24C01CT-I/SN is a 1-kbit (128 x 8) serial EEPROM utilizing 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 features a maximum access time of 900 ns and a page write time of 1 ms. Packaged in an 8-SOIC format, it is rated for industrial temperatures from -40°C to +85°C. Key electrical specifications include a maximum active read current of 3 mA and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports high-speed 400 kHz clock compatibility alongside standard 100 kHz operation for flexible bus integration.
• Includes a 16-byte page write buffer to optimize sequential data writing efficiency.
• Features Schmitt trigger inputs on all pins to suppress noise and ensure signal integrity.
• Incorporates output slope control mechanisms designed to eliminate ground bounce during switching.

Memory IC Applications

• Industrial control systems requiring non-volatile parameter storage
• Consumer electronics with limited pin count constraints
• Automotive modules operating within industrial temperature ranges
• Smart metering devices needing reliable long-term data retention

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) rather than commercial variants. Confirm the 'CT' designation indicates tape-and-reel packaging suitable for automated assembly processes. Ensure the 8-SOIC package width matches the target PCB footprint dimensions before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 1-kbit capacity suffices for small data sets like calibration constants or configuration flags. The I2C interface minimizes GPIO usage compared to SPI alternatives. Consider the 400 kHz speed if system latency requirements exceed standard 100 kHz limits. Verify that the 4.5 V minimum supply voltage aligns with the host system's power rail availability.

Memory IC Part Context

This part belongs to the 24C01C family of serial EEPROMs manufactured by Microchip Technology. The series offers various package options including SOIC, TSSOP, DFN, and MSOP. The 24C01CT-I/SN specifically denotes the industrial temperature grade version housed in an 8-pin Small Outline Integrated Circuit package with tape-and-reel delivery.

Memory IC Replacement Considerations

Direct substitutes within the same family include 24C01C-I/SN (tube packaging) and 24C01CT-I/ST (TSSOP-8 package). Cross-brand equivalents require verification of I2C address compatibility and voltage level matching.
