11LC160T-I/MNY

Overview

The Microchip Technology 11LC160T-I/MNY 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 TDFN package. It supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports the UNI/O single I/O serial interface protocol using Manchester encoding for combined clock and data transmission on the SCIO pin.
• Features built-in write protection mechanisms including power-on/off data protection circuitry and a write enable latch.
• Includes block write protection capabilities allowing configuration to protect none, one-quarter, one-half, or all of the memory array.
• Provides high reliability with Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.

Applications

• Interfacing with microcontrollers requiring low-pin-count non-volatile storage
• ASIC applications needing simple serial EEPROM access
• Systems utilizing discrete I/O lines configured for the UNI/O protocol

Procurement Notes

Verify that the specific ordering suffix corresponds to the TDFN-8 package and Industrial temperature grade (-40°C to +85°C). Confirm the device address code matches system requirements, as the 11LC160 uses address 0xA0. Ensure compatibility with the master controller's ability to generate the required UNI/O start headers and standby pulses.

Selection Notes

Select this component when a single-wire serial interface is preferred over multi-wire protocols like SPI or I2C. It is suitable for designs requiring low active current consumption and robust noise immunity via Schmitt triggers. Consider the page-write buffer size and block protection features if data integrity during partial writes is critical.

Part Context

This part belongs to the 11LCXXX family of 1 Kbit through 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features such as the UNI/O bus interface, self-timed write cycles, and similar electrical characteristics across various densities and package options.

Replacement Considerations

The 11LC160T-E/MNY serves as an automotive-grade replacement offering extended temperature range (-40°C to +125°C). Other density variants within the 11LC160 series may be compatible if memory size differences are acceptable.
