AT24C11N-10SU-2.7

Memory IC Overview

The AT24C11N-10SU-2.7 is a 1Kb (128 x 8) serial electrically erasable and programmable read-only memory (EEPROM). It operates with supply voltages ranging from 2.7V to 5.5V and supports clock frequencies up to 1 MHz at 2.7V, 2.5V, or 5V, and 400 kHz at 1.8V. The device utilizes a two-wire serial interface and features a 4-byte page write mode with self-timed write cycles of 5 ms maximum. It offers high reliability with 1 million write cycle endurance and 100-year data retention.

Memory IC Procurement Notes

Verify the specific voltage suffix (-2.7 vs -1.8) matches the target system supply range. Confirm package type availability as the datasheet lists multiple options including SOIC and TSSOP. Check current production status as older Atmel versions may have transitioned to Microchip Technology manufacturing lines.

Memory IC Selection Notes

Select this component when a 1Kb EEPROM size is required with I2C compatibility. Ensure the operating voltage aligns with the 2.7V to 5.5V specification. Consider the 4-byte page write limitation if large sequential writes are frequent. Verify temperature range requirements against the industrial rating.

Memory IC Part Context

This part belongs to the AT24C11 family of serial EEPROMs originally developed by Atmel Corporation and now managed by Microchip Technology. The family provides various voltage options and package styles to suit different space and power constraints in embedded memory applications.
