24LC00-I/SN

Memory IC Overview

The Microchip Technology 24LC00-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, output slope control to eliminate ground bounce, and ESD protection exceeding 4000V. 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 the master device via Start/Stop conditions.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C). Confirm the 'SN' suffix indicates the 8-lead SOIC package with a 3.90 mm body width. Ensure the component meets RoHS compliance requirements as specified in the datasheet.

Memory IC Selection Notes

Select this part when a small amount of non-volatile memory is required for low-speed data logging or configuration storage. The 24LC00 variant specifically requires a minimum supply voltage of 2.5V, distinguishing it from the 24AA00 series which supports operation down to 1.8V. Verify system voltage compatibility before integration.

Memory IC Part Context

This component belongs to the 24XX00 family of 128-bit serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA00 and 24C00, which share similar pinouts and protocols but differ in operating voltage ranges and temperature grades. The 24LC00 is optimized for standard 3.3V and 5V logic systems.

Memory IC Replacement Considerations

Public confirmed substitutes include the 24AA00-I/SN and 24C00-I/SN. Note that the 24AA00 supports lower voltages (1.8V), while the 24C00 requires higher voltages (4.5V minimum). Package and pinout compatibility must be verified for direct replacement.

Memory IC FAQ

How does the device handle acknowledge polling during write cycles?

During an internal write cycle, the device does not generate Acknowledge bits. A master can initiate ACK polling by sending a Start condition followed by the Write command control byte; if no ACK is returned, the device is still busy.

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

The slave address consists of the 4-bit code '1010' followed by three 'don't care' bits. These bits allow the device to monitor the bus for its specific address regardless of the state of those three bits.
