24C01-I

Memory IC Overview

The Microchip Technology 24C01-I is a 1-kbit (128 x 8) Electrically Erasable PROM featuring a standard two-wire serial interface compatible with I2C. 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 advanced CMOS technology for low-power consumption, offering a maximum read current of 1 mA and standby current of 5 µA. It guarantees over one million erase/write cycles and data retention exceeding 200 years. The industrial temperature grade (-40°C to +85°C) ensures reliable performance in demanding environments.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same two-wire bus
• Includes Schmitt trigger inputs for noise suppression
• Features output slope control to eliminate ground bounce
• Provides hardware write protection capabilities

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing I2C communication protocols
• Embedded applications needing configuration parameter retention
• Automotive modules operating within extended temperature ranges

Memory IC Procurement Notes

Verify the specific package suffix (e.g., P for PDIP, SN for SOIC, ST for TSSOP) as the base model 24C01-I does not specify it. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the voltage supply matches the 4.5V to 5.5V operational range. Check for any specific factory programming requirements if custom data initialization is needed.

Memory IC Selection Notes

Select this component when a 1-kbit capacity is sufficient for small data sets like calibration values or IDs. Choose the industrial grade variant for environments between -40°C and +85°C. Consider the 24C01A series for updated features such as page-write buffers if higher write throughput is required. Ensure the PCB layout accommodates the selected package type and I2C pull-up resistor requirements.

Memory IC Part Context

This part belongs to the Microchip 24C01/02/04 family of 5.0V I2C Serial EEPROMs. It shares the same core architecture and interface protocol with larger capacity variants like the 24C02 and 24C04. The 'I' designation indicates the industrial temperature range, distinguishing it from commercial or automotive grades within the same product line.

Memory IC Replacement Considerations

Direct substitutes include other 24C01 variants from Microchip with different packages or temperature ratings. Cross-manufacturer equivalents may exist but require verification of I2C compatibility and voltage levels. Ensure any replacement maintains the 128x8 organization and 400 kHz speed capability.
