24LC014H-E/SN

Memory IC Overview

The Microchip Technology 24LC014H-E/SN is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5 V to 5.5 V and supports a maximum clock frequency of 1 MHz via a 2-wire I²C compatible interface. The device features hardware write protection for half the array, low-power CMOS technology with standby current up to 1 μA, and data retention exceeding 200 years. It is housed in an 8-pin SOIC package and rated for extended temperature operation from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array.
• Low-power design ensures minimal active and standby current consumption.
• Schmitt trigger inputs provide noise suppression for reliable bus communication.
• Page write buffer allows efficient storage of up to 16 bytes per cycle.

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Calibration data retention in automotive electronics

Memory IC Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'E' suffix indicates an extended temperature range of -40°C to +125°C. The 'SN' suffix denotes an 8-lead small outline integrated circuit package. Confirm compliance with RoHS standards and lead-free manufacturing requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an I²C interface is required for non-volatile storage in high-temperature environments. Ensure the system voltage remains within the 2.5 V to 5.5 V operating range. Consider the 1 MHz clock speed for applications requiring faster data throughput compared to standard 400 kHz devices.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of 1 Kbit serial EEPROMs. The 24LC series is distinguished by its wider voltage operating range compared to the 24AA series. The device utilizes CMOS technology for low power consumption and includes built-in ESD protection exceeding 4,000V.

Memory IC Replacement Considerations

The 24LC014HT-E/SN serves as a tape-and-reel alternative to the tube-packaged version. Verify package dimensions and pin compatibility when substituting components in existing designs.
