AT24C32AW-10SI-2.7-T

Memory IC Overview

The AT24C32AW-10SI-2.7-T is a 32Kb (4096 x 8) serial electrically erasable and programmable read-only memory (EEPROM). It features a 2-wire serial interface compatible with I²C protocols, supporting clock rates of 100 kHz at 1.8V and 400 kHz at 2.5V to 5.5V. The device operates within a supply voltage range of 2.7V to 5.5V and includes hardware write protection via the WP pin. It supports page writes up to 32 bytes and offers high reliability with 1 million write cycle endurance and 100-year data retention.

Memory IC Feature Summary

• Supports bidirectional data transfer over a 2-wire serial bus with Schmitt trigger inputs for noise suppression.
• Provides hardware data protection through a dedicated Write Protect (WP) pin that inhibits all write operations when asserted high.
• Enables efficient bulk data storage using a 32-byte page write mode with partial page write capabilities.
• Features internally organized memory architecture allowing up to eight devices to share a common bus system.

Memory IC Applications

• Industrial and commercial systems requiring low-power non-volatile data storage
• Embedded applications needing persistent configuration parameter retention
• Devices utilizing standard I²C bus communication protocols

Memory IC Procurement Notes

Verify the specific suffix 'W' against official Microchip documentation to confirm package type and lead-free status. Confirm the '-T' designation indicates tape-and-reel packaging if required for automated assembly. Ensure the '-2.7' voltage option matches the target operating range of 2.7V to 5.5V. Cross-reference the manufacturer part number with current availability as product lifecycles may change.

Memory IC Selection Notes

Select this component for designs requiring 32Kb of non-volatile storage with I²C compatibility. It is suitable for environments where power consumption must be minimized during standby modes. Consider the 32-byte page size for optimizing write throughput compared to byte-write operations. Verify that the 2.7V minimum supply voltage aligns with the system's power rail specifications.

Memory IC Part Context

Memory IC FAQ

How does the Write Protect (WP) pin function?

When the WP pin is connected to VCC, all write operations to the memory are inhibited. Connecting it to GND allows normal write operations.

What is the maximum page write size?

The device supports a 32-byte page write mode, allowing multiple bytes to be written in a single sequence without intermediate stop conditions.
