24FC08T-E/SN

Memory IC Overview

The Microchip Technology 24FC08T-E/SN is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I²C protocols, supporting clock frequencies up to 1 MHz across the full supply voltage range of 1.7V to 5.5V. The device utilizes low-power CMOS technology, ensuring standby currents of 3 µA maximum and active read currents of 1 mA maximum. It includes a 16-byte page write buffer, hardware write-protect capability via the WP pin, and operates within an extended temperature range of -40°C to +125°C in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports high-speed I²C communication with clock frequencies reaching 1 MHz
• Includes a 16-byte page write buffer for efficient data transfer operations
• Provides hardware write protection through the dedicated WP pin
• Features Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial control applications operating in extended temperature environments
• Consumer electronics utilizing I²C bus architectures
• Portable devices powered by single-supply voltages down to 1.7V

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature grade (-40°C to +125°C) and 'SN' indicates the 8-lead SOIC package. Confirm the presence of the 'T' suffix denotes tape-and-reel packaging if bulk quantities are required. Ensure the specific revision of the datasheet DS20001710M matches the production lot requirements for compatibility with existing system designs.

Memory IC Selection Notes

Select this component when operation below 2.5V is required alongside high-speed 1 MHz I²C performance, distinguishing it from the 24LC08B series which is limited to 400 kHz at lower voltages. The 24FC08T-E/SN is suitable for designs needing robust noise immunity via Schmitt triggers and hardware write protection. Consider the 8-SOIC footprint constraints and verify that the 1.7V minimum supply voltage aligns with the system power rails.

Memory IC Part Context

This device belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA08 and 24LC08B but offers superior speed characteristics at low voltages. The family supports multiple package options including DFN, MSOP, and TSSOP, providing flexibility for various PCB layout requirements while maintaining standard I²C compatibility.

Memory IC Replacement Considerations

The 24LC08T-E/SN serves as a direct pin-compatible alternative, though it operates at a maximum clock frequency of 400 kHz. The 24AA08T-E/SN is also compatible but similarly limited to 400 kHz speeds. Verify that the reduced bandwidth of these substitutes meets the timing requirements of the host controller before substitution.
