24FC08T-E/MUY

Memory IC Overview

The Microchip Technology 24FC08T-E/MUY is an 8-Kbit (1024 x 8) I²C Serial EEPROM in an 8-lead UDFN package. It operates with a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 1 MHz at VCC ≥ 2.5V, or 100 kHz at lower voltages. The device features a 16-byte page write buffer, hardware write-protect via the WP pin, and Schmitt trigger inputs for noise suppression. It is qualified for Extended temperature range (-40°C to +125°C), offers over 1 million erase/write cycles, and includes ESD protection exceeding 4,000V.

Memory IC Feature Summary

• Supports high-speed I²C communication with compatibility up to 1 MHz
• Includes a 16-byte page write buffer for efficient data transfer
• Provides hardware write-protection capability through the dedicated WP pin
• Features 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 sensor modules

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the Extended temperature grade (-40°C to +125°C) and 'MUY' specifies the 8-lead UDFN package. Ensure the source document explicitly lists this exact part number as available. Confirm RoHS compliance status if required by your manufacturing specifications. Cross-reference the datasheet revision date to ensure alignment with current design requirements.

Memory IC Selection Notes

Select this component when operation below 2.5V is required alongside high-speed 1 MHz bus performance, which distinguishes it from the 24LC08B variant limited to 400 kHz. The 24AA08 lacks the 1 MHz capability. Verify that the UDFN package footprint matches the PCB layout constraints. Ensure the application can accommodate the hardware write-protect pin functionality if data security is critical.

Memory IC Part Context

This device belongs to the 24XX08 family of 8-Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA08 and 24LC08B but offers distinct electrical characteristics regarding voltage ranges and maximum clock speeds. The family utilizes a standard two-wire serial interface compatible with I²C protocols.

Memory IC Replacement Considerations

Public confirmed substitutes include the 24AA08-I/MUY and 24LC08B-I/MUY. Note that the 24AA08 is limited to 400 kHz operation above 2.5V, while the 24LC08B requires a minimum of 2.5V and also supports only 400 kHz. The 24FC08 is unique within the family for supporting 1 MHz operation down to 1.7V.
