24C02CT-I/ST

Memory IC Overview

The Microchip Technology 24C02CT-I/ST is a 2-kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 4.5 V to 5.5 V and features an I²C-compatible two-wire serial interface with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, offering a maximum active read current of 3 mA and a standby current of 5 µA. It supports page write operations with an 8-byte buffer and includes Schmitt trigger inputs for noise suppression. The component is housed in an 8-pin Thin Shrink Small Outline Package (TSSOP) and is rated for industrial operating temperatures between -40 °C and +85 °C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus via hardware address inputs
• Includes output slope control to eliminate ground bounce during switching
• Features self-timed write cycles with automatic acknowledgment

Memory IC Applications

• Storage of calibration data and user configuration parameters
• Device identification and MAC address storage
• Embedded system data logging and sensor history caching

Memory IC Procurement Notes

Verify that the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C) and 'ST' denotes the TSSOP-8 package. Confirm the 'CT' suffix indicates cut-tape packaging rather than tube or reel formats. Ensure the datasheet matches the exact part number to validate voltage limits and interface compatibility before procurement.

Memory IC Selection Notes

Select this component when a 2-kbit non-volatile storage solution is required within a 4.5 V to 5.5 V power domain. It is suitable for applications needing I²C connectivity with fast-mode support up to 400 kHz. Consider this part for designs requiring small footprint surface-mount packaging and robust noise immunity through integrated Schmitt triggers.

Memory IC Part Context

This EEPROM belongs to the Microchip 24xx02 family of serial memories. It shares functional similarities with the 24AA02 and 24LC02B series but is optimized for standard 5 V logic levels. The 24C02CT-I/ST variant specifically targets industrial environments, providing reliability across a wider temperature spectrum compared to commercial grade equivalents.

Memory IC Replacement Considerations

Direct pin-compatible substitutes include the 24AA02C and 24LC02B series from Microchip. Verify that alternative manufacturers offer components with matching I²C addressing schemes and compatible write cycle times.
