24C04AE/P

Memory IC Overview

The Microchip Technology 24C04AE/P is a 4 Kbit (512 x 8) serial Electrically Erasable PROM featuring a two-wire I²C compatible interface. It operates within a voltage range of 2.5 V to 5.5 V and supports clock frequencies up to 400 kHz. The device utilizes an 8-pin PDIP package and is rated for industrial temperature ranges from -40°C to +85°C. Key electrical specifications include a maximum access time of 900 ns, a write cycle time of 5 ms, and guaranteed endurance of 1 million erase/write cycles with data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write protection mechanism safeguards the upper half of the memory block against accidental modification.
• Self-timed write cycle functionality automatically terminates programming operations without external intervention.
• Page-write buffer capability allows efficient sequential data storage across multiple bytes.

Memory IC Applications

• Industrial control systems requiring non-volatile parameter storage
• Consumer electronics utilizing low-power embedded memory
• Automotive modules operating in extended temperature environments

Memory IC Procurement Notes

Verify the specific suffix 'E' against official Microchip documentation to confirm if it denotes automotive qualification or extended temperature variants, as standard datasheets may not explicitly detail this suffix's unique functional impact. Ensure the PDIP-8 package matches your PCB footprint requirements. Cross-reference the manufacturer part number directly with authorized distributors to avoid obsolete or counterfeit components.

Memory IC Selection Notes

Select this component when a robust 4 Kbit EEPROM with hardware write protection is required for industrial applications. The 2.5 V to 5.5 V supply range ensures compatibility with various logic levels. Consider the 8-pin DIP package for through-hole prototyping or legacy board designs. Verify that the 400 kHz bus speed meets system timing constraints before finalizing the design.

Memory IC Part Context

This part belongs to the Microchip 24C04A series of serial EEPROMs, which are widely used for storing calibration data and configuration settings. The series is characterized by its CMOS technology, offering low power consumption compared to older NMOS devices. The 24C04 variant specifically provides 512 words of 8-bit storage, balancing capacity with pin count efficiency.

Memory IC Replacement Considerations

Compatible substitutes include the 24LC04B series for general-purpose applications and the AT24C04D series for lower voltage operation. Verify pinout compatibility and voltage thresholds before swapping. The 24AA04E series offers similar functionality with different addressing options.
