24C01C-I/ST

Memory IC Overview

The Microchip Technology 24C01C-I/ST is a 1-kbit (128 x 8) serial Electrically Erasable PROM featuring an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 4.5 V to 5.5 V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, ensuring minimal active and standby current consumption. It offers high endurance with over one million erase/write cycles and data retention exceeding 200 years. The component is housed in an 8-lead SOIC package and is rated for industrial operating temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports standard I²C bus communication with compatibility for both 100 kHz and 400 kHz clock speeds.
• Incorporates hardware write protection mechanisms to safeguard critical data integrity.
• Features self-timed erase and write cycles with automatic termination upon completion.

Memory IC Applications

• Industrial control systems requiring non-volatile parameter storage
• Consumer electronics for configuration and calibration data retention
• Embedded devices needing compact memory for small data sets

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' confirms the industrial temperature range (-40°C to +85°C) and the 8-lead SOIC package type. Ensure the order quantity aligns with manufacturer packaging standards. Confirm RoHS compliance status if required by your assembly process. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Memory IC Selection Notes

Select this part when a 1-kbit capacity is sufficient for application needs. The 4.5 V to 5.5 V supply requirement distinguishes it from lower-voltage variants like the 24LC series. The industrial temperature rating makes it suitable for environments where commercial grade components would fail. Verify that the host microcontroller supports the I²C protocol and can handle the required voltage levels.

Memory IC Part Context

This component belongs to the Microchip 24Cxx family of serial EEPROMs, which are widely used for storing small amounts of data in embedded systems. The 24C01C variant specifically provides 1-kbit density. The 'I' suffix denotes the industrial temperature range, while '/ST' indicates the 8-lead Small Outline Integrated Circuit (SOIC) package style.
