24FC02-E/ST

Memory IC Overview

The Microchip Technology 24FC02-E/ST 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 a standby current of up to 3 µA and an operating read current of 1 mA. It includes an 8-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports high-speed I²C communication at frequencies up to 1 MHz
• Features hardware write protection controlled by the WP pin
• Includes 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 microcontrollers
• Parameter retention in automotive electronics
• Calibration data storage in consumer devices

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and the suffix 'ST' specifies the 8-lead TSSOP package. Confirm the specific datasheet revision matches your design requirements. Ensure the application circuit provides adequate pull-up resistors for the I²C bus lines to support the 1 MHz clock speed.

Memory IC Selection Notes

Select this component when operation below 2.5V is required, as it supports voltages down to 1.7V unlike the 24LC02B series. Choose the 24FC02 over the 24AA02 if higher bus speeds up to 1 MHz are necessary. The extended temperature grade is suitable for harsh environments where standard industrial grades may not suffice.

Memory IC Part Context

This part belongs to the 24XX02 family of 2-Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA02 and 24LC02B but offers distinct electrical advantages regarding voltage range and clock speed compatibility within the same physical footprint options.

Memory IC Replacement Considerations

The 24LC02B serves as a compatible alternative for applications operating strictly above 2.5V, though it lacks 1 MHz support. The 24AA02 is suitable for lower voltage designs requiring only 400 kHz speed.
