11LC160-I/SN

Overview

The Microchip Technology 11LC160-I/SN is a 16 Kbit serial electrically erasable programmable read-only memory (EEPROM) organized as 2,048 x 8 bits. 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 SOIC package. Designed for industrial applications, it supports a temperature range from -40°C to +85°C.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding on the SCIO pin.
• Features built-in write protection mechanisms including power-on/off data protection and a write enable latch.
• Includes 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

• Interfacing with microcontrollers requiring low-pin-count non-volatile storage
• ASIC designs needing compact serial EEPROM solutions
• Industrial control systems operating within specified temperature ranges

Procurement Notes

Verify that the specific part number suffix corresponds to the required package type and temperature grade. Confirm that the design environment supports the UNI/O protocol timing requirements. Ensure supply voltage levels remain within the specified operational limits to maintain data integrity and device reliability during active and standby modes.

Selection Notes

Select this component when a single-wire interface is preferred to minimize pin count compared to standard SPI or I2C devices. Consider the 16-byte page buffer size for write efficiency. Verify compatibility with the master controller's ability to generate the specific start headers and acknowledge sequences defined by the UNI/O protocol specification.

Part Context

This device belongs to the 11LC160 family of serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including the UNI/O interface and similar command sets, differentiated primarily by memory density and package options. The 'I' suffix denotes the industrial temperature rating, while 'SN' indicates the 8-lead SOIC physical package format.
