AT24C1024-10CI-2.7

Memory IC Overview

The AT24C1024-10CI-2.7 is a 1,048,576-bit (131,072 x 8) serial electrically erasable and programmable read-only memory (EEPROM). It operates on a 2-wire serial interface with a clock rate of 400 kHz at 2.7V and 1 MHz at 5V. The device supports a supply voltage range of 2.7V to 5.5V and features hardware write protection via the WP pin. It includes Schmitt triggers and filtered inputs for noise suppression, allowing up to two devices to share a common bus.

Memory IC Feature Summary

• Supports bidirectional data transfer protocol with hardware and software data protection capabilities.
• Features internally organized page write mode allowing partial page writes and self-timed write cycles.
• Includes Schmitt triggers and filtered inputs designed for effective noise suppression.

Memory IC Applications

• Industrial applications requiring low-power operation
• Commercial applications utilizing low-voltage environments
• Embedded systems needing non-volatile configuration storage

Memory IC Procurement Notes

Verify the specific package type required, as the -10CI suffix corresponds to an 8-lead Leadless Array Package (LAP). Confirm that the 2.7V operating range aligns with the system power supply requirements. Ensure compatibility with the 2-wire serial interface timing specifications before integration into the design.

Memory IC Selection Notes

Select this component when a 1M-bit capacity is necessary within an 8-pin footprint. It is suitable for designs where space is limited but significant non-volatile storage is required. Consider the 2-device bus limit if multiple units are needed on the same line.

Memory IC Part Context

This part belongs to the AT24C1024 family of 2-wire serial EEPROMs manufactured by Microchip Technology. It provides high reliability with 100,000 write cycle endurance and 40-year data retention. The device is optimized for industrial and commercial use cases demanding robust performance in low-voltage conditions.

Memory IC Replacement Considerations

Compatible substitutes include other 1M-bit 2-wire serial EEPROMs from the AT24Cxx series, such as the AT24C1024B, provided they match the voltage and interface requirements.
