11LC080T-I/SN

Memory IC Overview

The Microchip Technology 11LC080T-I/SN is an 8Kb (1,024 x 8) serial EEPROM utilizing the UNI/O single-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports a maximum bus frequency of 100 kHz. The device features a 16-byte page-write buffer and self-timed write cycles with a typical duration of 5 ms. Designed for industrial applications, it functions reliably between -40°C and +85°C. Packaged in an 8-lead SOIC, it offers high endurance and data retention capabilities.

Memory IC Feature Summary

• Supports the UNI/O single I/O serial protocol using Manchester encoding on the SCIO pin
• Includes a 16-byte page-write buffer for efficient sequential data writing
• Features block write protection allowing configuration of none, 1/4, 1/2, or all array segments
• Integrates power-on/off data protection circuitry and a write enable latch

Memory IC Applications

• Microcontroller system memory for storing calibration constants
• Configuration storage in industrial control devices
• Data logging in low-pin-count embedded sensors
• Parameter retention in automotive electronic modules

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the 8-lead SOIC package and 'I' indicates the industrial temperature range. Confirm the specific revision level matches your design requirements. Ensure the supplier provides documentation confirming RoHS compliance and Pb-Free status as specified in the datasheet.

Memory IC Selection Notes

Select this component when a single-wire interface is required to minimize pin count. It is suitable for systems operating at 2.5V or higher where low standby current is beneficial. Consider the 16-byte page buffer size for write optimization. Verify that the host controller can generate the necessary UNI/O timing sequences and start headers.

Memory IC Part Context

This part belongs to the 11LCXXX family of serial EEPROMs from Microchip Technology. The family shares common UNI/O protocol characteristics but varies in density and voltage ranges. The 11LC series specifically requires a minimum supply voltage of 2.5V, distinguishing it from the 11AA series which supports lower voltages down to 1.8V.

Memory IC Replacement Considerations

Direct substitutes include other members of the 11LC family such as the 11LC040 or 11LC160 if density differences are acceptable. For lower voltage requirements, the 11AA080 series may be considered, though voltage specifications differ.
