11AA010T-I/MNY

Overview

The Microchip Technology 11AA010T-I/MNY is a 1 Kbit (128 x 8) serial EEPROM utilizing the UNI/O single-wire interface. It operates within a supply voltage range of 1.8 V to 5.5 V and supports a maximum bus frequency of 100 kHz. The device features industrial temperature ratings from -40°C to +85°C, housed in an 8-lead TDFN package.

Feature Summary

• Supports the patented UNI/O single I/O serial protocol using Manchester encoding for clock and data integration.
• Includes a STATUS register with write enable latch and write-in-progress bits for operational control.
• Features built-in power-on/off data protection and configurable block write protection.
• Utilizes low-power CMOS technology with Schmitt trigger inputs for noise suppression.

Applications

• Microcontroller system configuration storage
• Calibration data retention in embedded devices
• Low-pin-count sensor data logging

Procurement Notes

Verify the specific suffix 'I/MNY' corresponds to the Industrial temperature range (-40°C to +85°C) and the 8-lead TDFN package type. Confirm that the 'T' indicates tape and reel packaging if required by assembly equipment. Ensure compatibility with the 1.8V minimum operating voltage for the AA series.

Selection Notes

Select this component when a single-wire interface is required to minimize pin count on the host microcontroller. Choose the 11AA010 over the 11LC010 variant specifically for applications requiring operation down to 1.8V, as the LC series requires a minimum of 2.5V. Verify page write buffer requirements against application data throughput needs.

Part Context

This part belongs to the 11AA/11LC family of serial EEPROMs designed for space-constrained applications. The 11AA series is distinguished by its lower voltage capability compared to the 11LC series. The TDFN package provides a compact surface-mount solution suitable for high-density PCB layouts.

Replacement Considerations

The 11LC010T-I/MNY serves as a functional substitute but requires a minimum supply voltage of 2.5V instead of 1.8V. Other 11AA010 variants with different packages (e.g., SOT-23-3 or SOIC-8) are available but require schematic and layout modifications.
