24LC00T/ST

Memory IC Overview

The Microchip Technology 24LC00T/ST is a 128-bit (16 x 8) serial EEPROM featuring an I2C-compatible 2-wire interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, drawing typical active current of 500 µA and standby current of 1 µA. It offers data retention exceeding 200 years and endurance of over 1 million erase/write cycles. The component is housed in an 8-lead TSSOP package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• I2C compatible 2-wire serial interface with Schmitt trigger inputs for noise suppression
• Low-power CMOS design supporting single supply operation down to 2.5V
• Hardware data protection with high ESD tolerance exceeding 4000V
• Self-timed erase/write cycle with acknowledge polling capability

Memory IC Applications

• Storage of calibration values
• Storage of ID numbers
• Storage of manufacturing information

Memory IC Procurement Notes

Verify the specific ordering suffix 'ST' corresponds to the TSSOP-8 package variant when sourcing. Confirm that the 'I' temperature grade aligns with the required operational range of -40°C to +85°C. Ensure the selected distributor provides the tape-and-reel packaging format indicated by the 'T' suffix. Cross-reference the datasheet revision DS20001178J for accurate electrical specifications.

Memory IC Selection Notes

Select this component for applications requiring minimal non-volatile storage capacity where space efficiency is critical. The 24LC00T/ST is suitable for systems needing only small amounts of EEPROM for configuration data. Consider the 2.5V minimum operating voltage constraint compared to lower-voltage alternatives like the 24AA00 series if system power rails are below 2.5V.

Memory IC Part Context

This part belongs to the 24XX00 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA00 and 24C00, which share similar functional architectures but differ in operating voltage ranges and temperature grades. The 24LC00 specifically targets industrial applications requiring robust performance at standard logic voltages.
