24LC014-E/MS

Memory IC Overview

The Microchip Technology 24LC014-E/MS is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5V to 5.5V and supports I²C compatible 2-wire serial interfaces with maximum clock frequencies of 100 kHz and 400 kHz. The device features hardware write protection, a page write buffer for up to 16 bytes, and an access time of 900 ns. It is housed in an 8-lead MSOP package and is rated for industrial temperature ranges from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection capability for the entire memory array via the WP pin
• Page write buffer supporting sequential writes of up to 16 bytes
• I²C compatible bidirectional 2-wire serial interface bus
• High endurance with one million erase/write cycles

Memory IC Applications

• Data logging applications requiring non-volatile storage
• Configuration parameter storage in embedded systems
• Calibration data retention in industrial sensors
• Device identification and serial number storage

Memory IC Procurement Notes

Verify the specific ordering suffix 'E' confirms the automotive temperature grade (-40°C to +125°C) and the 'MS' indicates the 8-lead MSOP surface mount package. Confirm RoHS compliance status and lead-free material specifications against the latest manufacturer datasheet revision before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an I²C interface is required for low-pin-count EEPROM applications. The automotive temperature grade ensures reliability in high-heat environments. Ensure the system power supply remains within the 2.5V to 5.5V operating range to maintain proper functionality and data integrity during read and write operations.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of 1-Kbit serial EEPROMs manufactured by Microchip Technology. The 'LC' designation typically denotes the standard commercial or extended voltage range variants, while the '-E' suffix specifies the extended automotive temperature rating. The device utilizes CMOS technology for low power consumption.

Memory IC Replacement Considerations

Direct substitutes include other 1Kb I²C EEPROMs from Microchip such as the 24LC014-I/MS for industrial temperature grades. Cross-manufacturer replacements require verification of pin compatibility, voltage levels, and I²C timing parameters.
