24LC00/SN

Memory IC Overview

The Microchip Technology 24LC00/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 offers data retention exceeding 200 years and endurance of over one million erase/write cycles. The industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Memory IC Feature Summary

• Low-power CMOS technology with typical active current of 500 µA and standby current of 100 nA
• Integrated Schmitt trigger inputs and filter circuits for enhanced noise spike suppression on SDA and SCL pins
• Self-timed erase/write cycle with acknowledge polling capability to maximize bus throughput
• Hardware data protection via VCC threshold detector that disables write logic during low voltage conditions

Memory IC Applications

• Storage of calibration values and manufacturing information
• Retention of ID numbers and configuration parameters
• Small-scale non-volatile data logging in embedded systems

Memory IC Procurement Notes

Verify the specific suffix against official datasheets to confirm package type, as 'SN' denotes SOIC packaging. Confirm the temperature grade matches application requirements, noting that Industrial grade covers -40°C to +85°C. Ensure compatibility with system voltage levels, as this variant requires a minimum of 2.5V. Cross-reference part numbers with manufacturer documentation to avoid confusion with similar 24AA or 24C series devices.

Memory IC Selection Notes

Select this component when minimal non-volatile storage is required for small data sets such as IDs or settings. It is suitable for designs prioritizing low power consumption and robust noise immunity in noisy industrial environments. Consider the 8-pin SOIC package constraints and verify that the system bus speed does not exceed the supported 400 kHz limit. Ensure adequate pull-up resistors are implemented for the open-drain I2C interface.

Memory IC Part Context

This device belongs to the 24XX00 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA00 and 24C00 but differs in operating voltage ranges. While the 24AA00 supports operation down to 1.8V and the 24C00 requires 4.5V to 5.5V, the 24LC00 bridges these with a 2.5V to 5.5V range. All variants utilize the same 128-bit organization and I2C protocol.

Memory IC Replacement Considerations

Public confirmed substitutes include the 24LC00T-I/SN for tape-and-reel packaging variations. The 24LC00-I/P serves as a through-hole alternative using PDIP packaging. Verify electrical specifications match exactly before substitution, particularly regarding the minimum supply voltage requirements.
