AT24C32AW-10SI-2.7

Memory IC Overview

The AT24C32AW-10SI-2.7 is a 32Kb (4096 x 8) serial electrically erasable and programmable read-only memory (EEPROM). It operates within a supply voltage range of 2.7V to 5.5V and features a 2-wire serial interface compatible with I²C protocols. The device supports clock rates up to 400 kHz at 2.5V and 100 kHz at 1.8V. It includes hardware write protection via the WP pin, 32-byte page write capability, and self-timed write cycles. Endurance is rated for 1 million write cycles with data retention of 100 years.

Memory IC Feature Summary

• Supports bidirectional data transfer over a 2-wire serial interface with Schmitt trigger inputs for noise suppression.
• Provides hardware data protection through a dedicated Write Protect (WP) pin that inhibits all write operations when high.
• Enables efficient bulk data storage using a 32-byte page write mode with partial page write allowance.
• Features internal organization allowing up to eight devices to share a common bus via hardwired address pins.

Memory IC Applications

• Industrial and commercial systems requiring low-power and low-voltage operation
• Parameter configuration storage in microcontroller-based designs
• Calibration data and user preference memory management

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm availability status as product lifecycles may change. Ensure the selected variant matches the required operating voltage range and interface compatibility for the target application design.

Memory IC Selection Notes

Select this component for applications needing non-volatile storage with I²C connectivity. Consider the 2.7V to 5.5V operating range for standard voltage systems. Evaluate the 1 million cycle endurance and 100-year data retention for long-term reliability requirements. Check package options such as SOIC or TSSOP based on board space constraints.

Memory IC Part Context

This part belongs to the AT24C32A/64A family of serial EEPROMs manufactured by Microchip Technology (formerly Atmel). The family provides scalable memory densities optimized for embedded systems. The 'W' suffix typically denotes a specific package variation within the JEDEC SOIC form factor, while '-2.7' indicates the minimum operating voltage threshold.

Memory IC Replacement Considerations

Compatible substitutes include other AT24C32A variants with different suffixes for package or voltage changes. Cross-reference with AT24LC32A or AT24FC32 series for similar functionality, ensuring interface and voltage compatibility match the original design specifications.
