11LC010T-I/SN

Overview

The Microchip Technology 11LC010T-I/SN 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 offers high reliability with 1,000,000 erase/write cycle endurance and data retention exceeding 200 years. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding for clock and data transmission on a single pin.
• Includes built-in power-on/off data protection circuitry and a write enable latch to prevent accidental writes.
• Features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.
• Provides flexible block write protection allowing none, 1/4, 1/2, or all of the memory array to be protected.

Applications

• Microcontroller system configuration storage
• Calibration data retention in industrial sensors
• Device identification and parameter logging
• Low-pin-count embedded memory applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the supply voltage requirements align with the target application's operating range. Confirm RoHS compliance status if required by regulatory standards. Check for any recent revisions to the device specification that may affect compatibility.

Selection Notes

Select this component when a single-wire interface is required to minimize pin count and PCB routing complexity. It is suitable for applications needing non-volatile storage with moderate density and high endurance. Consider the 11AA series if operation below 2.5 V is necessary, as the 11LC series requires a minimum of 2.5 V. Evaluate the need for block write protection features for security-sensitive data.

Part Context

This part belongs to the 11LC010 family of serial EEPROMs from Microchip Technology. It shares the same core architecture and UNI/O interface as other devices in the 11XX series, differing primarily in memory density and voltage specifications. The family includes variants like the 11LC020 and 11LC040 for higher capacities.

Replacement Considerations

Direct substitutes include other members of the 11LC010 family such as 11LC010-I/P or 11LC010-I/MS, provided the package footprint matches. Cross-family replacements like the 11AA010 require verification of the lower voltage support and potential pinout differences.
