24FC02-E/P

Memory IC Overview

The Microchip Technology 24FC02-E/P is a 2-Kbit (256 x 8) serial EEPROM featuring an I²C interface with a maximum clock frequency of 1 MHz. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports extended industrial temperature conditions from -40°C to +125°C. The device utilizes low-power CMOS technology, offering standby currents as low as 3 µA at extended temperatures. It includes hardware write protection via the WP pin, an 8-byte page write buffer, and Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports high-speed I²C communication up to 1 MHz across the full operating voltage range
• Features hardware write protection that inhibits all memory writes when the WP pin is tied to VCC
• Includes an 8-byte page write buffer to optimize data transfer efficiency
• Provides robust noise immunity through Schmitt trigger inputs on SCL and SDA lines

Memory IC Applications

• Data logging in industrial control systems requiring extended temperature stability
• Configuration storage for embedded devices operating at low voltages
• Parameter retention in consumer electronics utilizing I²C buses
• Automotive applications meeting AEC-Q100 qualification standards

Memory IC Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and the 'P' indicates the 8-lead PDIP package. Confirm the device meets RoHS compliance requirements for your assembly process. Ensure the application circuit provides adequate pull-up resistors for the I²C bus to support the 1 MHz clock speed specified in the datasheet.

Memory IC Selection Notes

Select this component when an I²C EEPROM requires operation below 2.5V, as it supports voltages down to 1.7V unlike the 24LC02B series. Choose the PDIP package for through-hole prototyping or applications requiring manual insertion. Verify that the 1 MHz clock speed is supported by the host controller's I²C peripheral capabilities.

Memory IC Part Context

This part belongs to the 24XX02 family of 2-Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA02 and 24LC02B but offers higher bus speeds. The family is designed for non-volatile data storage in space-constrained environments using standard two-wire serial interfaces.

Memory IC Replacement Considerations

The 24AA02 serves as a functional substitute but is limited to 400 kHz operation. The 24LC02B is compatible electrically but requires a minimum supply voltage of 2.5V. Verify package compatibility when substituting with other 8-pin DIP variants within the same memory density class.
