24C01C-I/SN

Memory IC Overview

The Microchip Technology 24C01C-I/SN is a 1K-bit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 4.5V to 5.5V and utilizes a 2-wire I2C compatible serial interface supporting clock frequencies up to 400 kHz. The device features a maximum access time of 900 ns, a page write buffer of 16 bytes, and an internal self-timed write cycle of 1 ms. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using hardware address inputs A0, A1, and A2.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Features a 16-byte page write buffer to optimize data transfer efficiency.
• Provides enhanced ESD protection exceeding 4000V.

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• Multi-device I2C bus architectures

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, specifically 'SN' for the 8-lead SOIC variant. Confirm the temperature grade suffix corresponds to the intended operating environment, ensuring 'I' aligns with industrial specifications. Cross-reference the manufacturer part number against official datasheets to validate electrical characteristics and pinout compatibility before integration.

Memory IC Selection Notes

Select this component when a 5V logic system requires reliable non-volatile storage with standard I2C connectivity. The 128x8 organization suits small-scale data logging or calibration values. Ensure the application voltage remains strictly between 4.5V and 5.5V, as lower voltage operation is not supported by this specific model compared to other variants in the family.

Memory IC Part Context

This EEPROM belongs to the 24C01C series, which provides 1K-bit capacity across various packages including PDIP, SOIC, TSSOP, DFN, MSOP, and SOT-23. The series maintains consistent I2C protocol support while offering different physical form factors to accommodate diverse PCB layout constraints and space requirements in electronic designs.
