24FC01-E/P

Memory IC Overview

The Microchip Technology 24FC01-E/P is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) housed in an 8-Lead PDIP package. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports a maximum clock frequency of 1 MHz. The device features a 2-wire I2C compatible serial interface, hardware write-protect capability via the WP pin, and an 8-byte page write buffer. It is qualified for extended temperature operation from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication with Schmitt trigger inputs for noise suppression
• Includes hardware write-protect functionality to inhibit memory writes when the WP pin is tied to VCC
• Features an 8-byte page write buffer to optimize data transfer efficiency

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Automotive electronics applications demanding extended temperature range reliability
• Embedded devices needing configuration parameter retention

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the Extended temperature rating (-40°C to +125°C) aligns with system environmental requirements. Ensure the 1.7V minimum operating voltage is compatible with the target system power rails before finalizing procurement.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I2C performance is required alongside low-voltage operation down to 1.7V. The PDIP package is suitable for through-hole mounting or prototyping environments. Consider the hardware write-protect feature if physical protection against accidental overwrites is necessary for the application design.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA01 and 24LC01B but offers superior bus speed capabilities. The device utilizes a standard I2C protocol for address and data transmission within a single memory block organization.

Memory IC Replacement Considerations

Direct substitutes include other 24FC01 variants with different packages such as 24FC01-I/SN or 24FC01-E/MS. Cross-family replacements like the 24AA01 or 24LC01B are possible but require verification of reduced clock frequency limits and voltage thresholds.
