24FC64FT-I/OT

Memory IC Overview

The Microchip Technology 24FC64FT-I/OT is a 64 Kbit (8K x 8) Electrically Erasable PROM featuring a 2-Wire I2C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device utilizes low-power CMOS technology, drawing a maximum read current of 400 µA and standby current of 1 µA. It includes hardware write protection for the upper quarter of the array and supports page writes of up to 32 bytes. The component is housed in a 5-lead SOT-23 package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection for the upper quarter of the memory array
• Supports cascading up to eight devices on a single bus
• Schmitt trigger inputs provide noise suppression
• Output slope control eliminates ground bounce

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Advanced low-power electronic designs

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the device version corresponds to the FC series specifications, particularly regarding the 1 MHz clock capability at various voltage levels. Ensure compatibility with the target system's I2C bus voltage requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a high-speed 1 MHz I2C EEPROM is required alongside low-voltage operation down to 1.7V. The SOT-23 package is suitable for space-constrained surface mount designs. Consider the hardware write-protect feature if protecting the upper memory addresses is necessary without software overhead.

Memory IC Part Context

This part belongs to the 24XX64F family of serial EEPROMs, which also includes the 24AA64F and 24LC64F variants. While sharing similar memory organization and interface protocols, the 24FC64F is distinguished by its support for higher clock frequencies compared to standard versions. The 'T' suffix indicates tape and reel packaging, while 'I' denotes the industrial temperature rating.

Memory IC Replacement Considerations

Direct functional substitutes within the same family include the 24FC64F-I/SN or 24FC64F-I/ST, provided the package footprint differs. For identical pinout replacement, verify availability of other 24FC64F variants in the SOT-23-5 package.
