24FC08T-E/OT

Memory IC Overview

The Microchip Technology 24FC08T-E/OT is an 8-Kbit (1K x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire serial interface compatible with I²C. It supports clock frequencies up to 1 MHz and operates on a single supply voltage ranging from 1.7V to 5.5V. The device utilizes low-power CMOS technology, offering a maximum read current of 1 mA and standby current of 3 µA in the extended temperature grade. It provides hardware write protection via the WP pin and includes Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports high-speed I²C communication with clock frequencies up to 1 MHz
• Includes a 16-byte page write buffer for efficient data transfer
• Features hardware write protection controlled by the WP pin
• Equipped with Schmitt trigger inputs and output slope control for signal integrity

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage in consumer electronics
• Parameter retention in automotive embedded controllers
• Calibration data storage in medical instrumentation

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 revision level of datasheet DS20001710M matches your design requirements. Ensure compatibility with the host controller's I²C bus timing specifications, particularly regarding rise times and clock stretching during write cycles.

Memory IC Selection Notes

Select this component when operation below 2.5V is required, as it supports voltages down to 1.7V unlike the 24LC08B series. Choose the E-grade variant for environments exceeding 85°C. The SOT-23-5 package is suitable for space-constrained surface-mount designs. Verify that the application does not require the Chip Scale Package (CSP), which lacks the hardware write-protect feature available in other packages.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs, sharing architectural similarities with the 24AA08 and 24LC08B. While all three offer 8-Kbit capacity and I²C interfaces, the 24FC08 is distinguished by its 1 MHz clock speed capability and lower minimum operating voltage of 1.7V. It serves as the high-performance, low-voltage option within this memory family.

Memory IC Replacement Considerations

Direct functional substitutes include the 24FC08T-I/OT for industrial temperature range applications or the 24AA08T-E/OT if 400 kHz speed is sufficient. Note that the 24LC08B series requires a minimum of 2.5V and is limited to 400 kHz.
