24LC00T-I/ST

Memory IC Overview

The Microchip Technology 24LC00T-I/ST is a 128-bit (16 x 8) serial Electrically Erasable PROM featuring a 2-wire I²C compatible interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with typical active current of 500 µA and standby current of 100 nA. The device supports clock frequencies up to 400 kHz, offers data retention exceeding 200 years, and withstands over one million erase/write cycles. It is housed in an 8-lead TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• I²C compatible 2-wire serial interface for efficient bus communication
• Low-power CMOS technology enabling minimal active and standby currents
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Self-timed erase/write cycle with hardware write protection capabilities

Memory IC Applications

• Storage of calibration values
• Retention of identification numbers
• Recording manufacturing information

Memory IC Procurement Notes

Verify the specific suffix 'T/I/ST' confirms the TSSOP-8 tape and reel packaging configuration. Ensure the 'I' designation matches the required industrial temperature range of -40°C to +85°C for your application environment. Confirm RoHS compliance status if restricted substances are a constraint. Cross-reference the datasheet revision to ensure compatibility with existing design specifications.

Memory IC Selection Notes

Select this component when a small EEPROM capacity is sufficient for non-volatile data storage. The 24LC00 series is appropriate for applications requiring low power consumption and simple serial connectivity. Consider the 2.5V minimum operating voltage requirement compared to other variants that support lower voltages. Evaluate the 400 kHz maximum clock speed against system timing requirements.

Memory IC Part Context

This part belongs to the 24AA00/24LC00/24C00 family of 128-bit serial EEPROMs. While sharing core architecture, the 24LC00 variant specifically requires a minimum supply voltage of 2.5V, distinguishing it from the 24AA00 which operates down to 1.8V. All variants utilize the same 2-wire serial interface protocol and pinout configurations across available packages.

Memory IC Replacement Considerations

The 24AA00T-I/ST serves as a functional substitute with identical pinout and interface, though it supports a lower minimum voltage of 1.8V. The 24C00T-I/ST is also compatible but requires a higher minimum voltage of 4.5V. Verify voltage levels match before swapping.
