24AA64-I/SN

Memory IC Overview

The Microchip Technology 24AA64-I/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 via a two-wire I2C compatible serial interface. The device features a 32-byte page write buffer, hardware write-protect capability, and Schmitt trigger inputs for noise suppression. It is designed for industrial temperature applications (-40°C to +85°C) and utilizes low-power CMOS technology with a maximum active current of 3 mA.

Memory IC Feature Summary

• Supports bidirectional data transmission using a standard two-wire serial bus protocol
• Includes a 32-byte page write buffer to optimize data writing efficiency
• Provides hardware write protection through the dedicated WP pin
• Features Schmitt trigger inputs to enhance noise spike suppression

Memory IC Applications

• Personal communications devices requiring non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Industrial control units utilizing I2C communication buses

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the SOIC-8 package type required for your design. Confirm the industrial temperature grade matches your operational environment specifications. Ensure compatibility with the host controller's I2C voltage levels and pull-up resistor requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 64-Kbit capacity is sufficient for the application's data storage needs. It is suitable for designs requiring operation down to 1.7V, distinguishing it from higher voltage variants like the 24LC64 series. Consider the SOIC-8 surface mount package if space constraints preclude through-hole mounting options.

Memory IC Part Context

This part belongs to the 24XX64 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24FC64 and 24LC64, which share similar functional architectures but differ in speed and voltage specifications. The 'I' designation indicates the industrial temperature range, while '/SN' specifies the 8-lead SOIC package configuration.

Memory IC Replacement Considerations

The 24AA64T-I/SN serves as a tape-and-reel alternative to the tube-packaged 24AA64-I/SN. Other family members like the 24LC64-I/SN offer similar functionality but require a minimum operating voltage of 2.5V instead of 1.7V.
