24C01CT-I/ST

Memory IC Overview

The Microchip Technology 24C01CT-I/ST is a 1-kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It features an I2C-compatible two-wire serial interface supporting clock frequencies up to 400 kHz. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes an 8-lead SOIC package. Key electrical specifications include a maximum access time of 900 ns, a standby current of 5 µA, and a write cycle time of 1 ms.

Memory IC Feature Summary

• Supports high-speed 400 kHz operation alongside standard 100 kHz mode for flexible bus integration
• Includes a 16-byte page write buffer to optimize data writing efficiency
• Provides hardware write protection capabilities to prevent accidental data modification

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage in consumer electronics
• Parameter retention in automotive instrumentation

Memory IC Procurement Notes

Verify the suffix 'I' indicates the industrial temperature range (-40°C to +85°C) and '/ST' denotes the specific SOIC-8 tape and reel packaging configuration. Confirm RoHS compliance status matches project requirements. Ensure the ordering quantity aligns with the manufacturer's standard reel size to avoid partial reel handling issues during procurement.

Memory IC Selection Notes

Select this component when a 1-kbit non-volatile storage solution is required with I2C connectivity. It is suitable for applications needing moderate speed and reliable data retention. Consider alternative packages if board space constraints differ from the SOIC-8 footprint. Verify that the 4.5 V minimum operating voltage aligns with the system power rail.

Memory IC Part Context

This part belongs to the 24C01C family of serial EEPROMs manufactured by Microchip Technology. The family offers various package options including PDIP, SOIC, TSSOP, DFN, and MSOP. The 24C01CT variant specifically refers to the tape and reel packaging format, distinguishing it from tube-packaged versions like the 24C01C/SN.

Memory IC Replacement Considerations

Cross-reference with other 24C01C variants such as 24C01C-I/SN for tube packaging or 24C01CT-I/MC for DFN packaging. Verify pin compatibility and electrical specifications before substitution.
