11LC080T-E/TT

Overview

The Microchip Technology 11LC080T-E/TT is an 8 Kbit (1,024 x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes the UNI/O single-wire interface and operates within a voltage range of 2.5 V to 5.5 V. The device supports a maximum bus frequency of 100 kHz and features a 16-byte page-write buffer. It is housed in a SOT-23-3 package and is rated for extended industrial temperatures from -40°C to +125°C.

Feature Summary

• Supports the patented UNI/O single I/O serial protocol using Manchester encoding on a dedicated SCIO pin.
• Includes built-in write protection mechanisms such as power-on/off data protection and a write enable latch.
• Features block write protection allowing configuration to protect none, one-quarter, one-half, or all of the memory array.
• Provides high reliability with specified endurance of one million erase/write cycles and data retention exceeding two hundred years.

Applications

• Microcontroller system configuration storage
• Calibration data retention in industrial sensors
• Device identification and parameter logging

Procurement Notes

Verify that the ordering suffix matches the required temperature grade and package type. Confirm the specific revision level against the manufacturer datasheet to ensure compatibility with existing designs. Check for any recent product change notices regarding assembly or material composition updates before finalizing procurement orders.

Selection Notes

Select this component when a single-wire interface is required to minimize pin count on the host microcontroller. Ensure the operating voltage falls within the 2.5 V to 5.5 V range. Consider the 16-byte page buffer size for write efficiency and verify that the extended temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the 11LC family of UNI/O serial EEPROMs manufactured by Microchip Technology. The family offers densities ranging from 1 Kbit to 16 Kbit. The 'LC' designation indicates operation at a minimum voltage of 2.5 V, distinguishing it from the 'AA' series which supports lower voltages down to 1.8 V.

Replacement Considerations

Compatible substitutes include other members of the 11LC family such as the 11LC040 or 11LC160, provided the memory density and package footprint are acceptable for the design.
