11LC080T-E/MS

Overview

The Microchip Technology 11LC080T-E/MS is an 8 Kbit (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 clock frequency of 100 kHz. The device features a 16-byte page-write buffer and self-timed write cycles. It is housed in an MSOP-8 surface-mount package and is rated for an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding on the SCIO pin.
• Includes built-in power-on/off data protection circuitry and a write enable latch for enhanced reliability.
• Features Schmitt trigger inputs on the SCIO line to suppress noise and output slope control to eliminate ground bounce.
• Provides block write protection capabilities allowing configuration to protect none, one-quarter, one-half, or all of the memory array.

Applications

• Microcontroller systems requiring non-volatile storage with minimal pin count
• Industrial control devices operating in high-noise environments
• Automotive electronics requiring extended temperature stability

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the 'E' designation aligns with the necessary automotive-grade specifications for your application environment. Ensure compatibility with the master controller's ability to implement the UNI/O protocol timing requirements.

Selection Notes

Select this component when a single-wire interface is preferred over multi-wire protocols like SPI or I2C to conserve GPIO pins. Choose the Automotive ('E') variant if the application demands operation up to 125°C. Consider the MSOP-8 package for compact surface-mount designs requiring robust thermal performance.

Part Context

This part belongs to the 11LC family of serial EEPROMs from Microchip Technology. It shares architectural similarities with other members such as the 11LC040 and 11LC160, differing primarily in memory density and specific temperature ratings. The family utilizes a common instruction set and communication protocol across various package options.

Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Substitutions must match the UNI/O interface, voltage range, and temperature specifications.
