24AA64T-I/SN

Memory IC Overview

The Microchip Technology 24AA64T-I/SN is a 64-Kbit Electrically Erasable PROM (EEPROM) organized as an 8K x 8-bit memory block. It features a two-wire serial interface compatible with I2C protocols. The device operates on a single supply voltage ranging from 1.7V to 5.5V, supporting clock frequencies up to 400 kHz within the industrial temperature range of -40°C to +85°C. It utilizes low-power CMOS technology and includes hardware write protection.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial bus protocol
• Includes a 32-byte page write buffer for efficient data storage operations
• Features Schmitt trigger inputs to suppress noise spikes on communication lines
• Provides hardware write protection through the dedicated WP pin

Memory IC Applications

• Industrial control systems requiring non-volatile data retention
• Consumer electronics utilizing low-voltage power supplies
• Automotive qualified applications meeting AEC-Q100 standards
• Embedded systems needing cascaded device addressing capabilities

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the SOIC-8 package type and tape-and-reel delivery format. Confirm the industrial temperature grade matches the required operational environment limits. Ensure the component version aligns with current RoHS compliance requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 64-Kbit capacity is sufficient for application needs. Choose this part over variants if operation below 2.5V is required, as other series members may have higher minimum voltage thresholds. Consider the package availability and lead times associated with the specific reel configuration requested.

Memory IC Part Context

This device belongs to the 24XX64 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24FC64 and 24LC64 models but differs in maximum clock frequency specifications and minimum operating voltage requirements. The 'I' designation indicates the industrial temperature rating.

Memory IC Replacement Considerations

Direct substitutes include the 24AA64T-I/ST for TSSOP packaging or the 24AA64T-I/MC for DFN packaging. Verify electrical compatibility regarding voltage ranges and interface timing before substituting.
