24AA64FT-I/MNY

Memory IC Overview

The Microchip Technology 24AA64FT-I/MNY is a 64 Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It features a 2-wire I²C serial interface with a maximum clock frequency of 400 kHz and an access time of 900 ns. The device operates on a single supply voltage ranging from 1.7 V to 5.5 V, consuming a maximum active read current of 400 µA and a standby current of 1 µA. It utilizes a TDFN-8 surface-mount package and supports an industrial temperature range from -40°C to +85°C.

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the device revision aligns with your design specifications. Ensure the supplier provides documentation confirming RoHS compliance and Pb-free status. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 64 Kbit capacity is required alongside hardware-level write protection for critical data segments. The wide 1.7V to 5.5V supply range allows compatibility with various logic levels without external level shifting. The TDFN-8 package offers a compact footprint suitable for space-constrained printed circuit board layouts compared to larger through-hole alternatives.

Memory IC Part Context

This EEPROM belongs to the 24XX64F family, which includes variants like the 24LC64F and 24FC64F. These devices share identical pinouts and core functionality but differ in speed ratings and minimum operating voltages. The 'I' designation indicates an industrial temperature rating, while the 'T' suffix typically denotes tape-and-reel packaging for automated assembly processes.

Memory IC Replacement Considerations

Compatible substitutes include other members of the 24XX64F family such as the 24LC64F or 24FC64F, provided their specific voltage and speed requirements match the application constraints. Verify that any replacement maintains the same TDFN-8 package dimensions and pin configuration to ensure mechanical compatibility.
