11LC010T-E/TT

Overview

The Microchip Technology 11LC010T-E/TT 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, self-timed write cycles, and block write protection. It is housed in a 3-lead SOT-23 package and rated for an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Supports the patented UNI/O single I/O serial protocol using Manchester encoding on the SCIO pin.
• Includes built-in power-on/off data protection and a write enable latch for array security.
• Features Schmitt trigger inputs for noise suppression and output slope control to minimize ground bounce.
• Provides high reliability with one million erase/write cycle endurance and over 200 years of data retention.

Applications

• Embedded systems requiring non-volatile storage for configuration parameters.
• Low-pin-count microcontroller interfaces where GPIO conservation is critical.
• Industrial monitoring devices operating in extended temperature environments.
• Battery-powered applications benefiting from low standby current consumption.

Procurement Notes

Verify that the 'E' suffix corresponds to the Automotive temperature grade (-40°C to +125°C), as the datasheet specifies this range for the E variant. Confirm the 'TT' suffix indicates the SOT-23-3 package type. Ensure the design accounts for the specific UNI/O protocol timing requirements and the 16-byte page boundary constraints during write operations.

Selection Notes

Select this component when a single-wire interface is required to minimize PCB trace count. The 11LC010 offers a compact solution for small data storage needs compared to parallel EEPROMs. Consider the 16-byte page size limitation for write efficiency. The extended temperature rating makes it suitable for harsher environments than standard Industrial grade parts.

Part Context

This part belongs to the 11LCXXX family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 11AA series but differs in minimum operating voltage and temperature ratings. The family utilizes a common instruction set and UNI/O protocol, allowing for potential software compatibility across different densities within the same interface standard.
