24FC04T-E/OT

Memory IC Overview

The Microchip Technology 24FC04T-E/OT is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) utilizing a two-wire I²C serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device features a 16-byte page write buffer, self-timed erase/write cycles, and hardware write protection via the WP pin. It supports industrial temperature ranges (-40°C to +85°C) and extended ranges (-40°C to +125°C). Packaged in a 5-lead SOT-23 format, it offers low-power CMOS technology with standby current as low as 1 µA.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication for efficient data transfer
• Includes a 16-byte page write buffer to optimize write operations
• Features hardware write protection to secure memory content
• Provides Schmitt trigger inputs for enhanced noise suppression

Memory IC Applications

• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor modules
• Device identification and serial number storage

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature range (-40°C to +125°C) and 'OT' indicates the 5-lead SOT-23 package. Confirm the specific datasheet revision matches your design requirements. Ensure voltage levels are compatible with the 1.7V minimum operating threshold. Check for RoHS compliance status if required by your manufacturing standards.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is sufficient for application needs. Choose the 24FC04 variant over 24AA04 or 24LC04B specifically for its 1 MHz clock speed capability at voltages down to 1.7V. The SOT-23 package is suitable for space-constrained surface-mount designs. Ensure the system can handle the 5 ms maximum write cycle time during power-down events.

Memory IC Part Context

This part belongs to the 24XX04 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA04 and 24LC04B but distinguishes itself through higher bus speeds. The family utilizes a standard I²C protocol, allowing compatibility with various microcontrollers. The 24FC04 series is designed for applications requiring reliable non-volatile data storage with low power consumption.
