24C01C-E/SN

Memory IC Overview

The Microchip Technology 24C01C-E/SN is a 1-kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes a 2-wire I2C interface with a maximum clock frequency of 400 kHz. The device operates within a supply voltage range of 4.5 V to 5.5 V and features an access time of 3.5 µs. Packaged in an 8-lead SOIC, it supports surface mount installation and functions across an industrial temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed 400 kHz I2C communication protocol
• Operates reliably in extended industrial temperature environments up to 125°C
• Provides long-term data retention capabilities exceeding 200 years

Memory IC Applications

• Industrial control systems requiring robust data storage at elevated temperatures
• Embedded devices utilizing standard I2C bus architectures
• Equipment needing non-volatile configuration parameter storage

Memory IC Procurement Notes

Verify the specific suffix 'E' corresponds to the extended temperature grade (-40°C to +125°C) rather than commercial grades. Confirm the 'SN' designation indicates the 8-lead SOIC package type. Ensure compatibility with 4.5V to 5.5V supply rails, as this variant does not support lower voltage operation found in other series members.

Memory IC Selection Notes

Select this component when applications demand operation above 85°C, distinguishing it from the standard 'I' grade which typically tops out at 85°C. The 400 kHz speed suits most general-purpose microcontroller interfaces. Verify that the 5V nominal supply aligns with the system design, as this part lacks low-voltage variants.

Memory IC Part Context

This EEPROM belongs to the 24C01 family of 1-kbit serial memories. The 'E' suffix denotes the extended industrial temperature rating, while 'SN' specifies the plastic small-outline integrated circuit package. It shares the core architecture with other 24C01 variants but offers wider thermal tolerance for harsher operating conditions.

Memory IC Replacement Considerations

The 24C01C-I/SN serves as a direct physical substitute but is limited to an 85°C maximum operating temperature. Other 24C01 variants in different packages may require PCB layout adjustments.
