24C02A-E/P

Memory IC Overview

The Microchip Technology 24C02A-E/P is a 2-kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes a two-wire I²C compatible serial interface for data communication. The device operates at a maximum clock frequency of 400 kHz and supports a supply voltage range of 4.5 V to 5.5 V. It is housed in an 8-pin PDIP package and is rated for industrial temperature operation from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protect functionality
• Self-timed write cycle with auto-erase
• Page-write buffer capability

Memory IC Applications

• Embedded system configuration storage
• Device calibration data retention
• Industrial control parameter logging

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates automotive-grade reliability (-40°C to +125°C) rather than standard industrial grade, as datasheets may vary by revision. Confirm the 'P' suffix corresponds to the PDIP package type required for your through-hole assembly process. Ensure the 4.5V minimum operating voltage aligns with your system's power rail specifications before procurement.

Memory IC Selection Notes

Select this component when high-temperature resilience up to 125°C is mandatory for the application environment. The 4.5V to 5.5V operating range restricts usage in low-voltage systems below 4.5V. Consider alternative models if a wider voltage range or lower power consumption is required for battery-operated devices.

Memory IC Part Context

This part belongs to the 24C02 series of serial EEPROMs manufactured by Microchip Technology. These devices are designed for non-volatile data storage in applications requiring frequent updates. The series is widely used in consumer electronics and industrial equipment for storing user settings and system parameters.

Memory IC Replacement Considerations

The 24C02C-E/P is a verified substitute within the same product family offering identical pinout and functional specifications.
