24LC014-I/P

Memory IC Overview

The Microchip Technology 24LC014-I/P is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5 V to 5.5 V and supports I²C compatible 2-wire serial interfaces with clock frequencies up to 400 kHz. The device features hardware write protection, a page write buffer for up to 16 bytes, and self-timed write cycles with a maximum duration of 5 ms. It is housed in an 8-lead PDIP package and rated for industrial temperatures between -40°C and +85°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
• Self-timed internal write cycle mechanism with automatic erase-before-write
• I²C bus compatibility allowing connection of up to eight devices on a single bus

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial control units needing reliable storage for calibration data
• Consumer electronics utilizing low-power serial memory for user settings
• Automotive modules operating within extended temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'P' indicates the 8-lead PDIP package. Confirm the specific voltage range requirements match the 2.5V to 5.5V specification for the LC variant. Ensure the application design accounts for the 400 kHz maximum clock frequency and the 5 ms write cycle time when planning bus throughput.

Memory IC Selection Notes

Select this component when a 1 Kbit EEPROM capacity is required with I²C interface compatibility. The Industrial temperature grade makes it suitable for environments exceeding standard commercial limits. Consider the PDIP package only if through-hole mounting is necessary for mechanical stability or prototyping. Verify that the system power supply remains within the 2.5V to 5.5V operational window to ensure correct functionality.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. The 'LC' designation specifically denotes operation down to 2.5V, distinguishing it from the 'AA' variant which supports lower voltages starting at 1.7V. The 'I' suffix identifies the Industrial temperature rating, while 'E' would indicate an Automotive grade. This family utilizes a standardized I²C protocol for efficient data transfer.

Memory IC Replacement Considerations

The 24LC014H series offers similar functionality but may support higher clock speeds depending on the specific sub-model. Cross-referencing with the 24AA014 requires verifying voltage compatibility, as the AA variant supports lower supply voltages. Always confirm package dimensions and pinout compatibility before substituting.
