11LC160T-E/SN

Overview

The Microchip Technology 11LC160T-E/SN 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 Manchester encoding for clock and data transmission. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum bit rate of 100 kbps. It features a 16-byte page-write buffer, self-timed write cycles, and block write protection capabilities.

Feature Summary

• Supports the UNI/O single I/O serial interface using Manchester encoding on the SCIO pin
• Includes built-in 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 hardware block write protection allowing configuration to protect none, one-quarter, one-half, or all of the array

Applications

• Microcontroller system data storage
• ASIC configuration memory
• Industrial control systems requiring extended temperature operation
• Automotive electronic modules

Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the SOIC-8 package and 'E' indicates the automotive temperature grade (-40°C to +125°C). Confirm the specific density matches the 16Kbit requirement. 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 serial interface is required to minimize pin count. Choose the 11LC160 variant over the 11AA series if the application requires a minimum operating voltage of 2.5 V rather than 1.8 V. The automotive grade ensures reliability in high-temperature environments compared to industrial grade options.

Part Context

This part belongs to the 11LC160 family of 1-Kbit through 16-Kbit serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including the UNI/O bus protocol, page-write buffers, and status register controls. Variants differ primarily in density, voltage ranges, and package types.

Replacement Considerations

Compatible substitutes include other members of the 11LC160 family such as 11LC160-I/MS or 11LC160-MNY, provided the package type and temperature rating align with the design requirements.
