24AA044-E/P

Memory IC Overview

The Microchip Technology 24AA044-E/P is a 4-Kbit (512 x 8) I²C Serial EEPROM housed in an 8-pin PDIP package. It operates on a single supply voltage ranging from 1.7V to 5.5V, supporting low-voltage applications. The device features a maximum clock frequency of 1 MHz and utilizes low-power CMOS technology with a maximum active read current of 400 µA and standby current of 1 µA at +85°C. It ensures data retention for up to 200 years and functions within a temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports wide operating voltage range from 1.7V to 5.5V for flexible power integration
• Utilizes low-power CMOS technology to minimize active and standby current consumption
• Ensures long-term data integrity with a specified retention period of 200 years

Memory IC Applications

• Battery-powered devices requiring operation at voltages as low as 1.7V
• Industrial systems needing extended temperature performance up to +125°C
• Embedded memory storage for configuration data in consumer electronics

Memory IC Procurement Notes

Verify the specific suffix 'E/P' confirms the PDIP-8 through-hole package and industrial temperature grade. Confirm RoHS compliance status via the official datasheet. Ensure the source document matches the manufacturer Microchip Technology. Check for any recent Product Change Notifications that may affect specifications or packaging details before finalizing procurement.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is required with I²C interface compatibility. Choose the 24AA044-E/P over higher-speed variants if the 1 MHz clock limit is sufficient for the application. Consider the 1.7V minimum voltage requirement for ultra-low-power designs compared to standard 2.5V or 5V only EEPROMs. Verify the PDIP-8 package fits the PCB layout constraints.

Memory IC Part Context

This part belongs to the 24AA044 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with other 4-Kbit I²C devices but is distinguished by its 1.7V minimum operating voltage and 1 MHz clock speed. The '-P' suffix specifically denotes the plastic dual in-line package, differentiating it from surface-mount options like MS or SN.

Memory IC Replacement Considerations

The 24AA044BH-E/P is a related variant within the same family. Note that the BH series typically supports a lower minimum voltage of 1.8V and may have different electrical characteristics. Verify pinout compatibility and voltage thresholds before substituting.
