11LC010T-I/MNY

Overview

The Microchip Technology 11LC010T-I/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 bus frequency of 100 kHz. The device features a 16-byte page write buffer, Schmitt trigger inputs for noise suppression, and output slope control to minimize ground bounce. It offers high reliability with 1,000,000 erase/write cycles endurance and data retention exceeding 200 years. The component is housed in an 8-lead TDFN package and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding for combined clock and data transmission on the SCIO pin.
• Includes built-in write protection mechanisms such as power-on/off data protection circuitry and a configurable block write protection feature.
• Features a STATUS register for monitoring write-in-progress status and managing write enable latches without interrupting operations.

Applications

• Microcontroller-based systems requiring non-volatile data storage for configuration parameters.
• Industrial control applications needing reliable memory in environments with electrical noise.
• Embedded devices utilizing single GPIO pins for memory access to conserve pin count.

Procurement Notes

Verify the specific suffix 'I/MNY' corresponds to the Industrial temperature grade (-40°C to +85°C) and the 8-lead TDFN package type. Confirm that the ordering code matches the 11LC010 density variant rather than other family members like 11AA or 11LC160. Ensure compatibility with the UNI/O protocol implementation in the host system before finalizing procurement.

Selection Notes

Select this component when a single-wire interface is required to minimize PCB trace usage compared to standard SPI or I2C memories. Choose the 11LC010T-I/MNY over the 11AA series if the application requires a minimum operating voltage of 2.5 V rather than 1.8 V. Consider the TDFN package for compact surface-mount designs where leaded packages are unsuitable.

Part Context

This part belongs to the 11XX family of serial EEPROMs from Microchip Technology, which includes variants ranging from 1 Kbit to 16 Kbit. The family shares common architectural features such as the UNI/O interface and similar command sets, differing primarily in memory density, voltage ranges, and available package options.

Replacement Considerations

Direct substitutes within the same package and interface include other 11LC010 variants with different suffixes, such as 11LC010-I/MS (MSOP) or 11LC010-I/P (PDIP). Cross-family replacements like the 25LC010 require significant interface changes due to SPI compatibility.
