11LC160T-E/MS

Overview

The Microchip Technology 11LC160T-E/MS is a 16 Kbit (2,048 x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes the UNI/O single I/O bus interface with a maximum clock frequency of 100 kHz. The device operates within a supply voltage range of 2.5 V to 5.5 V and is housed in an 8-lead MSOP package. Designed for automotive applications, it supports an extended temperature range from -40°C to +125°C.

Feature Summary

• Supports the UNI/O single I/O serial interface protocol using Manchester encoding on the SCIO pin.
• Includes built-in write protection mechanisms such as power-on/off data protection and a write enable latch.
• Features a 16-byte page-write buffer to facilitate efficient sequential data writing operations.
• Provides block write protection capabilities allowing configuration to protect none, one-quarter, one-half, or all of the memory array.

Applications

• Automotive electronic systems requiring non-volatile data storage
• Microcontroller-based embedded designs utilizing single I/O interfaces
• Industrial control units needing reliable parameter retention

Procurement Notes

Verify that the specific ordering suffix corresponds to the Automotive grade (-E) and tape-and-reel packaging (T), distinct from Industrial grade or tube packaging variants. Confirm the manufacturer part number matches the exact density and organization required for the target application design specifications.

Selection Notes

Select this component when a single-wire serial interface is preferred to minimize pin count compared to standard SPI or I2C devices. Ensure the system voltage remains within the 2.5 V to 5.5 V operational range and that the environmental conditions meet the extended automotive temperature requirements specified for the -E suffix.

Part Context

This device belongs to the 11LC160 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with other members of the 11XX series but is distinguished by its specific 16 Kbit capacity and automotive-grade reliability ratings.

Replacement Considerations

Compatible substitutes include the 11LC160-I/MS for industrial temperature ranges and the 11LC161T-E/MS which utilizes a different device address code.
