24AA64-E/SN

Memory IC Overview

The Microchip Technology 24AA64-E/SN is a 64-Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports a maximum clock frequency of 400 kHz. The device utilizes a two-wire serial interface compatible with I2C protocols. It features Schmitt trigger inputs for noise suppression, hardware write protection, and output slope control. The component is housed in an 8-lead SOIC package and supports extended temperature operation.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using three address pins
• Includes hardware write protection via the WP pin to inhibit array writes
• Features Schmitt trigger inputs for improved noise spike suppression
• Provides output slope control to eliminate ground bounce during switching

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications operating in extended temperature environments
• Automotive electronic modules requiring AEC-Q100 qualified components
• Low-power portable devices utilizing I2C communication buses

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the specific package type and temperature grade required for your design. Confirm the presence of the 'E' designation indicates extended temperature range capability. Ensure compatibility with the host system's I2C voltage levels and pull-up resistor requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 64-Kbit EEPROM with low-voltage operation down to 1.7V is required. The extended temperature variant is suitable for harsh environments where standard industrial grades are insufficient. Consider the 8-lead SOIC package for through-hole or surface-mount assembly needs. Verify that the 400 kHz clock speed meets the system's data throughput requirements.

Memory IC Part Context

This part belongs to the 24AA64/24FC64/24LC64 family of 64-Kbit I2C Serial EEPROMs. The 'AA' prefix denotes low-voltage operation starting at 1.7V, distinguishing it from the 2.5V minimum 24LC64 series. The 'E' suffix specifies the extended temperature range, while 'SN' identifies the 8-lead Small Outline Integrated Circuit package format.

Memory IC Replacement Considerations

The 24AA64-I/SN serves as the industrial temperature equivalent. The 24LC64-SN offers similar functionality but requires a minimum supply voltage of 2.5V. The 24FC64-SN provides higher clock speeds up to 1 MHz. Verify package dimensions and electrical specifications when substituting.
