24AA64FT-I/MS

Memory IC Overview

The Microchip Technology 24AA64FT-I/MS is a 64 Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It features a 2-wire I2C compatible serial interface and operates on a single supply voltage ranging from 1.7V to 5.5V. The device supports clock frequencies up to 400 kHz at VCC ≥ 2.5V, with reduced compatibility at lower voltages. It includes hardware write-protect for the upper quarter of the array (addresses 1800h-1FFFh) via the WP pin. The component utilizes a 32-byte page write buffer and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Hardware write-protect capability for the upper quarter of the memory array
• Supports cascading up to eight devices on a single bus using functional address pins
• Integrated Schmitt trigger inputs for enhanced noise suppression
• Output slope control designed to eliminate ground bounce effects

Memory IC Applications

• Personal communications systems requiring low-power non-volatile storage
• Data acquisition applications needing reliable parameter retention
• Embedded controllers utilizing I2C bus architecture
• Industrial equipment operating within extended temperature ranges

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP-8 package and tape-and-reel delivery format. Confirm the industrial temperature grade designation matches the required operational range. Ensure the part number explicitly indicates the FT suffix for reel packaging rather than tube packaging. Cross-reference the manufacturer's latest datasheet revision to confirm active status and compliance details before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 64 Kbit EEPROM with I2C interface is required in a surface-mount MSOP-8 package. It is suitable for designs needing operation down to 1.7V with low standby current. Consider the hardware write-protect feature if partial array security is necessary. Verify that the 400 kHz maximum clock frequency meets system timing requirements and that the 32-byte page buffer aligns with write throughput needs.

Memory IC Part Context

This device belongs to the 24AA64F/24LC64F/24FC64F family of 64 Kbit serial EEPROMs. It shares core electrical characteristics with the 24AA64F series but differs in packaging and delivery format. The 'I' suffix denotes the Industrial temperature range, while 'MS' specifies the MSOP-8 package type. The 'FT' suffix indicates Tape and Reel packaging, distinguishing it from tube-packed variants within the same electrical specification group.

Memory IC Replacement Considerations

Direct substitutes include other 24AA64F variants with identical electrical specifications but different packages or packaging formats, such as 24AA64F-I/ST or 24AA64F-I/SN. Ensure any replacement maintains the 1.7V to 5.5V operating voltage range and I2C compatibility. Verify that the physical footprint and pinout match the existing PCB layout if swapping between package types like TSSOP or SOIC.
