24FC02-E/MS

Memory IC Overview

The Microchip Technology 24FC02-E/MS 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
• Includes hardware write-protect capability via the WP pin
• Features an 8-byte page write buffer for efficient data transfer
• Provides Schmitt trigger inputs to suppress bus noise

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded devices
• Parameter retention in automotive electronics
• Calibration data storage in consumer appliances

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'MS' specifies the MSOP-8 package. Confirm RoHS compliance status and ensure the specific datasheet revision matches the design requirements. Check for any recent Product Change Notifications regarding assembly or material changes.

Memory IC Selection Notes

Select this component when a 1 MHz I²C speed is required alongside low-voltage operation down to 1.7V. The extended temperature grade is suitable for harsh environments where standard industrial parts may fail. Ensure the application can accommodate the MSOP-8 surface mount package dimensions and provides adequate pull-up resistors for the SDA and SCL lines.

Memory IC Part Context

This part belongs to the 24XX02 family of 2-Kbit serial EEPROMs from 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 applications requiring reliable byte-level access over a two-wire serial bus.

Memory IC Replacement Considerations

Direct functional substitutes within the same speed and voltage range include the 24AA02 (limited to 400 kHz below 2.5V) and 24LC02B (limited to 400 kHz). Verify package compatibility if replacing with other variants in the 24XX02 series.
