24LC014H-I/MS

Memory IC Overview

The Microchip Technology 24LC014H-I/MS is a 1 Kbit (128 x 8) serial electrically erasable PROM featuring 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 1 MHz in the Industrial temperature grade (-40°C to +85°C). The device utilizes low-power CMOS technology with maximum active current of 400 μA and standby current of 1 μA. It includes hardware write protection for half the array, a 16-byte page write buffer, and Schmitt trigger inputs for noise suppression.

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 efficient storage of up to 16 bytes per transaction.
• Schmitt trigger inputs provide enhanced noise suppression on SDA and SCL lines.

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter retention in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'MS' indicates the 8-lead MSOP package. Confirm the specific datasheet revision matches the required electrical characteristics, as parameters may vary between preliminary and final releases. Ensure compatibility with the system's I²C bus voltage levels.

Memory IC Selection Notes

Select this component when a 1 Kbit EEPROM with high-speed 1 MHz I²C operation is required at voltages starting from 2.5V. It is suitable for designs needing hardware write protection for critical data segments. Compare against the 24AA014H if lower voltage operation down to 1.7V is necessary, noting that the AA variant is limited to 400 kHz.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of 1 Kbit Serial EEPROMs. The LC designation specifically denotes support for 1 MHz clock speeds and a minimum operating voltage of 2.5V, distinguishing it from the AA series which supports 1.7V but is limited to 400 kHz. Both share identical memory organization and physical package options.

Memory IC Replacement Considerations

The 24LC014H-I/SN is a direct functional substitute using the SOIC-8 package instead of MSOP. For applications requiring lower voltage operation (1.7V), the 24AA014H series is compatible but restricted to 400 kHz clock speeds.
