11LC080T-I/TT

Memory IC Overview

The Microchip Technology 11LC080T-I/TT is a serial electrically erasable programmable read-only memory (EEPROM) with an 8 kbit storage capacity organized as 1,024 x 8 bits. It operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum bus frequency of 100 kHz via the UNI/O single I/O interface. The device utilizes a SOT-23-3 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports the patented UNI/O single I/O serial protocol using Manchester encoding for combined clock and data transmission on the SCIO pin.
• Includes a 16-byte page-write buffer to allow efficient sequential data writing without repeated command overhead.
• Features built-in write protection mechanisms including power-on/off data protection and a configurable block write protection system.

Memory IC Applications

• Microcontroller-based systems requiring non-volatile data storage
• Industrial control devices needing reliable parameter retention
• Low-pin-count embedded applications constrained by I/O availability

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the design environment supports the UNI/O protocol timing requirements. Ensure the supply voltage remains within the specified operational limits to maintain data integrity and prevent electrical overstress during normal operation.

Memory IC Selection Notes

Select this component when a minimal pin count is critical for space-constrained designs. The UNI/O interface reduces board routing complexity compared to multi-wire buses. Consider the 16-byte page buffer size for write efficiency and verify that the 100 kHz speed meets the system's communication latency requirements.

Memory IC Part Context

This part belongs to the 11LCXXX family of serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features such as the UNI/O interface and similar command sets, differing primarily in memory density and physical packaging options available for each specific bit organization.

Memory IC Replacement Considerations

Compatible substitutes include other members of the 11LC series such as the 11LC040 or 11LC160, provided the memory density aligns with application needs. Verify that any replacement maintains compatibility with the existing firmware logic handling the UNI/O protocol sequences.
