24C04/P

Memory IC Overview

The Microchip Technology 24C04/P is a 4-kbit (512 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It utilizes a 2-Wire I2C interface with a maximum clock frequency of 400 kHz. The device operates within a supply voltage range of 2.5 V to 5.5 V and features a 900 ns access time. Packaged in an 8-pin PDIP, it supports through-hole mounting and functions across a temperature range of -40°C to +125°C. Data retention is specified at 200 years.

Memory IC Feature Summary

• Supports standard I2C bus modes including 100 kHz and 400 kHz operation for reliable data communication.
• Provides non-volatile storage with extended data retention capabilities suitable for long-term application requirements.
• Includes hardware write protection functionality to safeguard memory array integrity against accidental modification.

Memory IC Applications

• Embedded systems requiring persistent configuration storage
• Industrial control equipment needing parameter logging
• Smart metering devices for utility data recording

Memory IC Procurement Notes

Verify the specific suffix 'P' confirms the PDIP-8 package type when sourcing. Confirm the operating voltage range matches the system design, as this variant typically requires a minimum of 2.5 V. Ensure the I2C address pins are configured correctly for the target application environment.

Memory IC Selection Notes

Select this component for applications requiring through-hole mounting and robust industrial temperature performance. Compare against surface-mount variants if board space is constrained. Verify that the 400 kHz speed meets the system's timing requirements and that the 2.5 V minimum voltage aligns with the available power rails.

Memory IC Part Context

This part belongs to the 24LC/24C series of serial EEPROMs from Microchip Technology. These devices are widely used for storing small amounts of data in embedded systems. The 24C04 specifically offers 512 bytes of storage, balancing capacity with low pin count and simple interface requirements for cost-sensitive designs.

Memory IC Replacement Considerations

Check for direct substitutes such as the AT24C04 or M24C04. Verify package compatibility and voltage specifications before substitution. Note that some equivalents may have different temperature ranges or write cycle endurance ratings.
