24LC014HT-I/SN

Memory IC Overview

The Microchip Technology 24LC014HT-I/SN is a 1 Kbit (128 x 8) serial Electrically Erasable PROM featuring a 2-Wire 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 utilizes low-power CMOS technology with maximum active current of 400 μA and standby current of 1 μA. It includes Schmitt trigger inputs for noise suppression, output slope control to eliminate ground bounce, and hardware write protection for half the array. The component is housed in an 8-pin SOIC package.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array via the WP pin.
• Integrated page write buffer allows storage of up to 16 bytes before initiating an internal self-timed write cycle.
• Schmitt trigger inputs and filter circuits provide enhanced noise spike suppression for reliable operation on noisy buses.

Memory IC Applications

• Data logging applications requiring non-volatile storage of sensor readings or system parameters.
• Configuration storage for microcontroller-based systems needing persistent settings across power cycles.
• Device identification and calibration data retention in industrial instrumentation.

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range aligns with the target application, as the 'LC' variant specifies a minimum operating voltage of 2.5V. Ensure compatibility with the host controller's I2C bus speed and logic levels before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact 1 Kbit EEPROM with hardware write protection is required. It is suitable for designs needing high-speed communication up to 1 MHz at voltages above 2.5V. Consider the SOIC package dimensions for PCB layout constraints. Verify that the industrial temperature range meets the environmental requirements of the end product.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of 1 Kbit Serial EEPROMs. The 'LC' designation indicates a version optimized for higher clock speeds (up to 1 MHz) compared to the standard 400 kHz limit of the 'AA' counterpart. The 'I' suffix denotes the Industrial temperature range, while 'SN' identifies the 8-lead Small Outline Integrated Circuit package.

Memory IC Replacement Considerations

The 24LC014T-I/SN is a direct functional substitute within the same package and electrical specifications. Other members of the 24LC014H series may be considered if package variations are acceptable.
