11LC010T-E/MNY

Overview

The Microchip Technology 11LC010T-E/MNY is a 1 Kbit (128 x 8) serial EEPROM utilizing the UNI/O single-wire interface. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 100 kHz. The device features a 16-byte page-write buffer, self-timed write cycles, and block write protection. It is housed in an 8-lead TDFN package and rated for industrial temperature ranges from -40°C to +125°C.

Feature Summary

• Supports the UNI/O single I/O serial bus protocol using Manchester encoding for combined clock and data transmission.
• Includes built-in power-on/off data protection circuitry and a write enable latch for enhanced reliability.
• Features Schmitt trigger inputs on the SCIO pin to suppress noise and output slope control to eliminate ground bounce.

Applications

• Microcontroller system configuration storage
• Calibration data retention in sensor modules
• Device identification and parameter logging

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Automotive temperature grade (-40°C to +125°C) rather than the Industrial grade. Confirm the 'MN' suffix matches the required 8-lead TDFN package dimensions. Ensure the specific density variant (11LC010) is selected over other family members like 11LC020 or 11LC040.

Selection Notes

Select this component when a single-pin serial interface is required to minimize PCB trace count. The UNI/O protocol allows compatibility with any microcontroller possessing a configurable discrete I/O line. Consider the 16-byte page buffer size for write efficiency and verify that the 2.5 V minimum supply voltage aligns with the system's power rails.

Part Context

This part belongs to the 11XX family of 1 Kbit to 16 Kbit Serial Electrically Erasable PROMs. The family shares common architectural features including the UNI/O bus, Manchester encoding, and similar command sets. Variants differ primarily in memory density, operating voltage ranges, and temperature ratings.

Replacement Considerations

Public confirmed substitute part numbers: 11LC010-I/MS, 11LC010-I/TTO, 11LC010-E/MS.

FAQ

How does the UNI/O interface handle clock signals?

The UNI/O interface combines the clock and data into a single serial bit stream (SCIO) using Manchester encoding techniques, eliminating the need for a separate clock pin.

What is the function of the Write-In-Progress (WIP) bit?

The WIP bit indicates whether the device is currently busy with an internal write operation. A value of '1' signifies a write is in progress, while '0' indicates the device is ready for new commands.
