11LC160-E/MS

Overview

The Microchip Technology 11LC160-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 bus protocol using Manchester encoding on the SCIO pin.
• Includes built-in write protection mechanisms such as power-on/off data protection circuitry and a write enable latch.
• Features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.
• Provides block write protection 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 high reliability and long data retention

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Automotive grade (-40°C to +125°C) and '/MS' indicates the 8-lead MSOP package. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the specific revision level matches design requirements.

Selection Notes

Select this component when a single-wire serial interface is required to minimize pin count. Choose the 11LC160-E/MS variant specifically for automotive environments due to its extended temperature rating. Consider the 16-byte page-write buffer capability for efficient data writing operations.

Part Context

This part belongs to the 11LCXXX family of 1 Kbit to 16 Kbit serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including the UNI/O bus protocol and similar command sets, differing primarily in memory density and specific device addressing codes.

FAQ

How does the 11LC160-E/MS handle synchronization with the master device?

The device uses a start header consisting of a low pulse followed by an 8-bit code to synchronize its internal clock period with the master's clock period before any operation begins.

What is the function of the Write-In-Progress (WIP) bit?

The WIP bit indicates whether the device is currently busy with an internal write cycle; it is set to '1' during a write operation and '0' when idle.
