24LC024H-E/ST

Memory IC Overview

The Microchip Technology 24LC024H-E/ST is a 2 Kbit (256 x 8) serial EEPROM featuring an I2C-compatible interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 1 MHz. The device includes hardware write protection for the upper half of the memory array via the WP pin, utilizes Schmitt trigger inputs for noise suppression, and offers data retention exceeding 200 years with 1 million erase/write cycles.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array to prevent accidental modification.
• Integrated Schmitt trigger inputs provide enhanced noise spike suppression for reliable operation in electrically noisy environments.
• Supports page write operations allowing up to 16 bytes to be buffered internally before being committed to the memory array.

Memory IC Applications

• Industrial control systems requiring non-volatile storage for configuration parameters
• Embedded sensor nodes needing low-power data logging capabilities
• Automotive electronics demanding extended temperature range reliability

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the 'E' designation aligns with automotive-grade specifications if operating at elevated temperatures. Ensure the 'H' variant is selected for high-speed 1 MHz compatibility rather than standard 400 kHz models.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for application requirements. Choose this model over the 24AA024H variant if the system design restricts the minimum supply voltage to 2.5V rather than 1.7V. Consider the TSSOP-8 package for surface-mount assembly constraints.

Memory IC Part Context

This part belongs to the 24LC024H series of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA024H but differs in its specified operating voltage range. The series is designed for applications requiring robust data retention and simple two-wire serial communication protocols.

Memory IC Replacement Considerations

The 24LC024HT-E/ST serves as a tape-and-reel replacement for the tube-packaged 24LC024H-E/ST. Other family members like the 24LC024H-I/ST offer identical electrical characteristics within the industrial temperature range.
