AT24C64A-10TI-1.8

Memory IC Overview

The AT24C64A-10TI-1.8 is a 65,536-bit (8192 x 8) serial electrically erasable and programmable read-only memory (EEPROM). It operates with a supply voltage range of 1.8V to 5.5V and supports a clock frequency of 400 kHz at 1.8V. The device utilizes a 2-wire serial interface and features a 32-byte page write mode. It includes hardware data protection via a write protect pin and offers high reliability with one million write cycle endurance and 100-year data retention.

Memory IC Feature Summary

• Supports bidirectional data transfer over a 2-wire serial interface with Schmitt trigger filtered inputs for noise suppression.
• Provides hardware data protection through a dedicated write protect pin that inhibits all write operations when connected high.
• Enables efficient data writing via a 32-byte page write mode that allows partial page writes.

Memory IC Applications

• Industrial and commercial applications requiring low power and low voltage operation
• Embedded systems storing configuration parameters or calibration data
• Systems utilizing cascaded devices on a common 2-wire bus

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required voltage option and package type. Confirm the temperature range aligns with system requirements. Check for automotive grade availability if extended temperature performance is needed. Ensure compatibility with existing I2C bus protocols and address configurations before procurement.

Memory IC Selection Notes

Select this component for designs requiring non-volatile storage accessed via a standard two-wire interface. Consider the 1.8V to 5.5V operating range for flexibility in power supply design. Evaluate the 400 kHz clock rate for sufficient data throughput needs. Assess the need for hardware write protection to secure critical memory contents against accidental modification.
