24LC014H-I/P

Memory IC Overview

The Microchip Technology 24LC014H-I/P is a 1 Kbit (128 x 8) serial electrically erasable PROM featuring an I2C-compatible 2-wire interface. It operates within a voltage range of 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 offers hardware write protection for half the array, page write capability for up to 16 bytes, and data retention exceeding 200 years. The component is housed in an 8-pin PDIP package and functions across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array via the WP pin.
• Integrated Schmitt trigger inputs and noise filters suppress bus spikes to ensure reliable operation in noisy environments.
• Page write buffer allows efficient storage of up to 16 bytes of data in a single transaction.
• Low-voltage design minimizes power consumption with dedicated standby and active current specifications.

Memory IC Applications

• Industrial control systems requiring non-volatile parameter storage
• Embedded devices needing configuration data retention
• Consumer electronics utilizing I2C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, as the 'P' designation specifically indicates an 8-pin PDIP format. Confirm the temperature grade corresponds to your operational environment requirements. Ensure the voltage supply aligns with the specified 2.5V minimum threshold for this specific variant. Cross-reference the datasheet revision to confirm compatibility with your system design constraints.

Memory IC Selection Notes

Select this component when a robust 1 Kbit EEPROM solution is needed with hardware-level write protection capabilities. The 1 MHz clock speed supports high-throughput applications compared to standard 400 kHz variants. The PDIP package facilitates prototyping and through-hole assembly processes. Consider the low standby current for battery-operated designs where power efficiency is critical.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of serial EEPROMs manufactured by Microchip Technology. The family shares identical memory architecture and functional characteristics, differing primarily in operating voltage ranges and clock frequency limits. The 'LC' variant specifically supports higher speeds and lower minimum voltages compared to the 'AA' series.

Memory IC Replacement Considerations

The 24LC014H-I/SN serves as a direct functional substitute using an SOIC-8 surface mount package. The 24LC014H-I/MS provides an alternative MSOP-8 footprint option. Verify pinout compatibility and voltage specifications before substituting these packages in existing designs.
