24AA04/P

Memory IC Overview

The Microchip Technology 24AA04/P is a 4-Kbit (512 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 400 kHz at voltages above 2.5V, or 100 kHz below that threshold. The device features a two-wire I2C compatible serial interface with Schmitt trigger inputs for noise suppression. Key electrical characteristics include a maximum active read current of 1 mA, standby current of 1 µA, and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports low-voltage operation down to 1.7V with minimal power consumption
• Includes hardware write-protect capability via the WP pin
• Features output slope control to eliminate ground bounce during switching

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• Low-power consumer electronics operating on limited supply rails

Memory IC Procurement Notes

Verify the specific ordering suffix 'P' corresponds to the 8-Lead PDIP package type when sourcing components. Confirm the industrial temperature range (-40°C to +85°C) aligns with your operational environment requirements. Ensure the I2C bus pull-up resistor values are selected appropriately for the 400 kHz clock speed and supply voltage conditions defined in the datasheet specifications.

Memory IC Selection Notes

Select this component for applications requiring robust noise immunity through Schmitt trigger inputs and precise timing control via output slope management. The 24AA04/P is suitable for designs needing hardware-level write protection to prevent accidental data corruption. Consider the 16-byte page write buffer efficiency for bulk data updates compared to byte-write operations.

Memory IC Part Context

This part belongs to the 24XX04 family of 4-Kbit Serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24LC04B and 24FC04 variants but is distinguished by its lower minimum operating voltage of 1.7V. The PDIP package variant provides through-hole mounting options suitable for prototyping and high-reliability industrial assemblies.

Memory IC Replacement Considerations

Direct substitutes within the same package and specification profile include other 24AA04 variants such as 24AA04-I/SN or 24AA04-I/ST. Cross-family replacements like the 24LC04B require verification of the higher minimum voltage requirement (2.5V). Ensure any replacement maintains the 400 kHz I2C compatibility and 8-pin DIP footprint.
