24C02CT/ST

Memory IC Overview

The Microchip Technology 24C02CT/ST is a 2-kbit (256 x 8) serial EEPROM utilizing an I2C interface. It operates within a supply voltage range of 1.7V to 5.5V and supports clock frequencies up to 1 MHz. The device features a 900 ns access time and a 5 ms write cycle duration. It is housed in an SOT-23-5 surface-mount package and functions across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock rates up to 1 MHz
• Operates over a wide supply voltage range from 1.7V to 5.5V
• Provides non-volatile data retention for extended periods

Memory IC Applications

• Embedded systems requiring compact non-volatile storage
• Consumer electronics with limited board space
• Industrial control modules needing reliable parameter storage

Memory IC Procurement Notes

Verify the specific suffix 'ST' corresponds to the SOT-23-5 package and 1 MHz speed variant, distinct from the SN or MS packages. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 1.7V minimum voltage aligns with your system's power rails.

Memory IC Selection Notes

Select this component when a small SOT-23-5 footprint is required alongside high-speed I2C performance. It is suitable for applications demanding operation at lower voltages down to 1.7V. Compare against standard SOIC variants if board space allows for larger packages with potentially different thermal characteristics.

Memory IC Part Context

This part belongs to the 24C02 series of serial EEPROMs from Microchip Technology. It shares architectural similarities with other 2-kbit devices but differs in packaging and electrical specifications based on the suffix. The CT designation indicates tape and reel packaging for automated assembly.

Memory IC Replacement Considerations

AT24C02C-STUM-T is a confirmed substitute offering identical SOT-23-5 packaging and 1 MHz I2C interface capabilities.
