24AA64T-I/MC

Memory IC Overview

The Microchip Technology 24AA64T-I/MC is a 64-Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It features a two-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 400 kHz for standard operation and 100 kHz when VCC is below 2.5V. The device operates on a single supply voltage ranging from 1.7V to 5.5V. It utilizes low-power CMOS technology, drawing a maximum active current of 3 mA and a standby current of 1 µA. The component is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using three hardware address pins.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Features a 32-byte page write buffer for efficient data transfer operations.
• Provides hardware write protection via the WP pin to secure the entire memory array.

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial applications operating within the -40°C to +85°C temperature range
• I2C bus networks requiring multiple addressable EEPROM devices

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type and tape-and-reel delivery format. Confirm the industrial temperature grade designation matches the required operational environment. Ensure compatibility with the system's I2C voltage levels and pull-up resistor configurations before finalizing procurement.

Memory IC Selection Notes

Select this component for designs requiring low-voltage operation down to 1.7V and high endurance exceeding one million erase/write cycles. It is suitable for applications needing hardware write protection and compact surface-mount packaging. Consider alternative packages if physical space constraints differ or if extended automotive temperature ranges are necessary.

Memory IC Part Context

This part belongs to the 24XX64 family of 64-Kbit I2C Serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24LC64 and 24FC64, which share similar architectural features but differ in voltage specifications and maximum clock frequencies. The 'T' suffix indicates a reel packaging option, while 'MC' denotes the MSOP package style.

Memory IC Replacement Considerations

Direct substitutes within the same package and electrical specifications include other 24AA64 variants with different suffixes for package or temperature grades. Cross-family replacements like the 24LC64 or 24FC64 require verification of voltage range and clock speed compatibility.
