11LC160-E/P

Overview

The Microchip Technology 11LC160-E/P is a 16 Kbit serial electrically erasable programmable read-only memory (EEPROM) device. It features a UNI/O single I/O bus interface with a maximum clock frequency of 100 kHz. The memory organization is 2,048 x 8 bits. Operating voltage ranges from 2.5 V to 5.5 V. It is housed in an 8-lead PDIP package and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding for combined clock and data transmission on the SCIO pin.

Applications

• Interfacing with microcontrollers via discrete I/O lines
• ASIC communication systems
• Data storage requiring low-power standby modes

Procurement Notes

Verify the specific suffix 'E' confirms the automotive temperature grade (-40°C to +125°C) as per the datasheet selection table, while 'P' indicates the PDIP package. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a single-wire serial interface is required to minimize pin count. Ensure the system voltage falls within the 2.5 V to 5.5 V range. Consider the 16-byte page write buffer capability for efficient data writing operations compared to byte-by-byte programming.

Part Context

This device belongs to the 11XX family of serial EEPROMs, which includes variants like 11AA160 and 11LC161. The family shares common architectural features such as the UNI/O interface and similar command sets, differing primarily in density, voltage ranges, and device addressing codes.

Replacement Considerations

The 11LC161-E/P is a compatible alternative within the same package and temperature grade, distinguished by its different hardwired device address code ('0001' vs '0000'). Verify address configuration requirements before substitution.
