24LC014-E/P

Memory IC Overview

The Microchip Technology 24LC014-E/P is a 1 Kbit (128 x 8) serial electrically erasable PROM featuring a 2-wire I²C compatible interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology with typical active current of 1 mA and standby current of 1 µA at 5.5V. It offers hardware write protection, page write buffers for up to 16 bytes, and an endurance of 1,000,000 erase/write cycles. Data retention exceeds 200 years, and it includes ESD protection greater than 4,000V. This specific variant is rated for extended industrial temperature ranges from -40°C to +125°C and is housed in an 8-lead PDIP package.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication with I²C compatibility
• Features hardware write protection via the WP pin to inhibit array writes
• Includes a page write buffer allowing storage of up to 16 bytes before internal programming
• Provides high reliability with over 200-year data retention and 1 million write cycle endurance

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial control units operating in extended temperature environments
• Automotive electronics needing robust memory solutions with hardware write protection
• Sensor networks storing calibration data or device identifiers

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature grade (-40°C to +125°C) as specified in the datasheet selection table. Confirm the 'P' suffix indicates the 8-lead PDIP package type. Ensure the application voltage remains above 2.5V, as lower voltages may restrict clock frequency to 100 kHz. Cross-reference the manufacturer part number with official Microchip documentation to confirm RoHS compliance status.

Memory IC Selection Notes

Select this component when an extended temperature range is required for automotive or harsh industrial applications. The 24LC014-E/P differs from the standard Industrial grade (I) by its higher maximum operating temperature limit. Ensure the system design accommodates the 2.5V minimum supply voltage requirement. Consider the 8-lead PDIP package constraints if surface mount alternatives are not feasible for the specific PCB layout requirements.

Memory IC Part Context

This device belongs to the 24AA014/24LC014 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares identical functional architectures but varies in voltage ranges and temperature grades. The 24LC series specifically targets applications requiring operation down to 2.5V, distinguishing it from the 24AA series which supports lower voltages down to 1.7V. All variants maintain the same 128x8 organization and I²C interface protocols.

Memory IC Replacement Considerations

The 24LC014-I/P serves as a direct substitute if the extended temperature rating is unnecessary. For lower voltage applications, the 24AA014 series is compatible functionally but requires verification of the 1.7V support. Package variations such as SOIC or TSSOP offer footprint differences but retain electrical equivalence.
