24FC08-E/SN

Memory IC Overview

The Microchip Technology 24FC08-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 operates within an extended temperature range of -40°C to +125°C and is housed in an 8-lead Small Outline Integrated Circuit (SOIC) package.

Memory IC Feature Summary

• Supports high-speed serial communication with I²C compatibility up to 1 MHz
• Includes hardware write-protect functionality via the WP pin for data security
• Features Schmitt trigger inputs and noise suppression circuits for reliable operation on noisy buses
• Provides a 16-byte page write buffer to optimize write throughput

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter retention in consumer electronics
• Calibration data storage in automotive sensors

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature grade (-40°C to +125°C) and 'SN' specifies the 8-lead SOIC package. Confirm RoHS compliance status and ensure the specific revision matches the design requirements. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Memory IC Selection Notes

Select this component when low-voltage operation down to 1.7V is required alongside high-speed 1 MHz I²C performance. The extended temperature rating makes it suitable for harsh environments where standard industrial grades are insufficient. Ensure the application utilizes the hardware write-protect feature if data integrity against accidental writes is critical.

Memory IC Part Context

This device belongs to the 24XX08 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA08 and 24LC08B but offers superior speed capabilities. The 24FC08 variant is specifically designed to support faster bus speeds compared to its lower-frequency counterparts while maintaining low power consumption characteristics.

Memory IC Replacement Considerations

Direct replacements include the 24AA08 or 24LC08B if reduced clock frequency is acceptable. Verify pinout compatibility and voltage thresholds when substituting. Note that the 24FC08 supports higher speeds; slower alternatives may require timing adjustments in the host controller firmware.
