24C00T-E/ST

Memory IC Overview

The Microchip Technology 24C00T-E/ST is a serial EEPROM memory device with a storage capacity of 128 bits, organized as 16 x 8. It utilizes a 2-Wire I2C interface supporting clock frequencies up to 400 kHz. The component operates within a supply voltage range of 4.5 V to 5.5 V and features an access time of 3.5 us. It is housed in an SOT-23-5 package, suitable for surface mount installation, and supports data retention for 200 years.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock rates up to 400 kHz
• Provides non-volatile data storage with extended 200-year retention capability
• Operates reliably across a wide industrial temperature range from -40°C to +125°C

Memory IC Applications

• Embedded systems requiring small-scale non-volatile configuration storage
• Industrial control devices needing parameter retention under extreme temperatures
• Consumer electronics utilizing I2C-based memory for calibration data

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +125°C) compared to commercial variants. Confirm the 'T' suffix denotes tape-and-reel packaging compatible with automated assembly lines. Ensure the 'ST' designation matches the required SOT-23-5 footprint on your PCB layout. Cross-reference the datasheet revision date to confirm electrical characteristics remain unchanged.

Memory IC Selection Notes

Select this part when a compact SOT-23-5 package is mandatory for space-constrained designs. Choose this model over larger capacities if only minimal configuration data storage is required. Verify that the system power supply strictly adheres to the 4.5V to 5.5V operating range to ensure reliable I2C signaling. Consider the 400 kHz speed limit if higher bus speeds are needed for other components.

Memory IC Part Context

This component belongs to the Microchip 24C00 series of serial EEPROMs. It shares the I2C interface architecture with larger capacity parts like the 24C02 or 24C04 but offers reduced storage density. The series is designed for low-power applications where data persistence is critical without battery backup.

Memory IC Replacement Considerations

The 24C00-I/ST serves as a commercial-grade alternative with a narrower temperature range. The 24C00T-E/MNY offers identical electrical specifications but utilizes a TDFN-8 package instead of SOT-23-5.
