24C02C-E/SN

Memory IC Overview

The Microchip Technology 24C02C-E/SN is a 2-kbit (256 x 8) electrically erasable programmable read-only memory (EEPROM) integrated circuit. It operates on a single supply voltage ranging from 4.5 V to 5.5 V and utilizes an I²C-compatible two-wire serial interface with a maximum clock frequency of 100 kHz. The device features a write cycle time of 1.5 ms per word or page, with an access time of 3.5 µs. It is housed in an 8-SOIC package and supports operation across an extended industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus for expanded memory capacity
• Includes Schmitt trigger inputs on all pins to suppress noise and improve signal integrity
• Features output slope control mechanisms designed to eliminate ground bounce during switching

Memory IC Applications

• Industrial control systems requiring data retention at elevated temperatures
• Consumer electronics utilizing standard I²C communication protocols
• Automotive embedded applications operating within extended thermal environments

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature rating (-40°C to +125°C) rather than commercial grade. Confirm the 'SN' suffix corresponds to the 8-SOIC package variant. Check RoHS compliance status against current manufacturing notices. Ensure the 100 kHz speed class matches system timing requirements instead of faster variants.

Memory IC Selection Notes

Select this component when extended temperature operation is mandatory alongside standard 5V logic levels. Compare against the 24C02C-I/SN if only industrial temperatures are needed. Consider the AT24C02C series for lower voltage compatibility or higher speed interfaces. Verify pinout compatibility with existing PCB footprints before finalizing the design.

Memory IC Part Context

This part belongs to the 24C02C family of 2-kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with other members like the 24C02C-I/SN but differs in specified operating temperature ranges. The SOIC-8 package provides a surface-mount solution suitable for automated assembly processes in compact electronic designs.
