24LC024T-I/MC

Memory IC Overview

The Microchip Technology 24LC024T-I/MC is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5V to 5.5V and features a 2-wire I2C compatible interface with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, offering typical standby current of 1 μA and active read current of 1 mA. It supports page write operations with a 16-byte buffer and includes hardware write protection via the WP pin. The component is housed in an 8-lead DFN package and is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on a single bus using hardware address pins A0, A1, and A2.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Features self-timed erase/write cycles with automatic acknowledge polling capability.

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention for sensor modules

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage range requirements align with the 2.5V minimum specification for the LC series. Ensure compatibility with the I2C bus pull-up resistor values for the target clock speed. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this part when a compact surface-mount solution is needed for small-scale non-volatile data storage. The 24LC024T variant provides tape-and-reel packaging suitable for automated assembly processes. Consider the automotive grade version if extended temperature ranges beyond 85°C are required. Verify that the hardware write-protect feature meets the security requirements of the application design.

Memory IC Part Context

This component belongs to the 24AA024/24LC024 family of 2K I2C Serial EEPROMs manufactured by Microchip Technology. The family shares identical functional architectures but differs in voltage specifications and temperature ratings. The 'I' designation indicates industrial temperature range availability, while the 'MC' suffix specifies the 8-lead DFN package configuration.

Memory IC Replacement Considerations

Direct substitutes include the 24LC024T-E/MC for extended temperature applications or the 24LC024T-I/MNY for alternative DFN footprints. Cross-brand equivalents such as STMicroelectronics M24C02 variants may require voltage level verification due to different operating ranges.
