24LC00T-I/SN

Memory IC Overview

The Microchip Technology 24LC00T-I/SN is a 128-bit (16 x 8) serial EEPROM utilizing 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 features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce. It is housed in an 8-lead SOIC package with a width of 3.90 mm and is rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology ensures typical active current of 500 µA and standby current of 100 nA.
• Integrated Schmitt trigger inputs and filter circuits suppress noise spikes on the SDA and SCL lines.
• Output slope control circuitry eliminates ground bounce during switching operations.
• Self-timed erase/write cycles are initiated by a Stop condition without requiring external timing.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds specifically to the 8-lead SOIC package variant. Confirm the temperature grade 'I' matches the required industrial operating range of -40°C to +85°C. Ensure the voltage specification aligns with the 2.5V minimum requirement for the LC series, distinct from the AA series which supports lower voltages.

Memory IC Selection Notes

Select this component when a small amount of non-volatile memory is required for simple data logging or configuration storage. The I²C interface minimizes pin count usage on the PCB. Consider the 128-bit capacity limits; if larger storage is needed, evaluate higher-density parts within the 24LCxx family while maintaining the same interface protocol.

Memory IC Part Context

This part belongs to the 24AA00/24LC00/24C00 family of 128-bit serial EEPROMs. The 'LC' designation indicates operation down to 2.5V, whereas 'AA' variants support 1.8V and 'C' variants require 4.5V. The 'T' suffix typically denotes tape and reel packaging, while 'I' specifies the industrial temperature grade.

Memory IC FAQ

How does the device indicate when an internal write cycle is complete?

The device does not generate Acknowledge bits during the self-timed write cycle. Master devices can use acknowledge polling by sending a Start condition followed by the control byte; if the device acknowledges, the write cycle is complete.

What is the function of the 'don't care' bits in the slave address?

The slave address consists of the 4-bit device code '1010' followed by three 'don't care' bits. These bits allow the device to monitor the bus regardless of their state, simplifying addressing for this specific density level.
