24FC04-I/P

Memory IC Overview

The Microchip Technology 24FC04-I/P is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I²C serial interface. It operates within a supply voltage range of 1.7V to 5.5V and supports clock frequencies up to 1 MHz. The device utilizes low-power CMOS technology with a maximum read current of 1 mA and standby current of 1 µA at industrial temperatures. It offers hardware write protection, a 16-byte page write buffer, and data retention exceeding 200 years. The component is housed in an 8-lead PDIP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I²C communication with compatibility for 100 kHz, 400 kHz, and 1 MHz clock frequencies.
• Includes a 16-byte page write buffer to optimize data transfer efficiency during write operations.
• Features Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Provides hardware write protection via the WP pin to secure memory contents against unauthorized modifications.

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor interfaces

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C). Confirm the 'P' suffix indicates the 8-lead PDIP through-hole package. Ensure the specific revision matches the required datasheet version DS20001708P. Cross-reference the manufacturer part number to avoid confusion with similar capacity devices like the 24AA04 or 24LC04B which have different speed or voltage specifications.

Memory IC Selection Notes

Select this component when an I²C EEPROM requires operation down to 1.7V with speeds up to 1 MHz. The Industrial temperature rating suits general-purpose applications where extended automotive qualification is not mandatory. Compare against the 24LC04B if only 400 kHz speed is needed, or the 24AA04 if lower power consumption at reduced voltages is prioritized over bus speed.

Memory IC Part Context

This device belongs to the 24XX04 family of 4-Kbit serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA04 and 24LC04B but distinguishes itself by supporting higher clock frequencies up to 1 MHz. The family utilizes a common pinout and protocol, facilitating design flexibility across different performance and voltage requirements within the same product line.

Memory IC Replacement Considerations

The 24AA04 serves as a functional substitute if 400 kHz operation suffices. The 24LC04B is compatible for designs operating above 2.5V. Verify package availability and temperature ratings when substituting, as the 'I' suffix denotes Industrial grade while 'E' denotes Extended grade.
