11LC161T-E/MNY

Overview

The Microchip Technology 11LC161T-E/MNY is a 16 Kbit (2048 x 8) serial EEPROM utilizing the UNI/O single-wire interface. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 100 kHz. The device features a TDFN-8 package, industrial temperature rating (-40°C to +85°C), and high reliability with 1,000,000 write/erase cycles and over 200 years data retention.

Feature Summary

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

• Interfacing with microcontrollers requiring low pin-count non-volatile storage
• ASIC applications needing simple serial data logging
• Systems requiring robust data retention in industrial environments

Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range up to +125°C and 'MNY' denotes the TDFN-8 package. Confirm RoHS compliance status via official documentation before integration. Ensure supply chain sources provide authentic Microchip components to guarantee specified endurance and retention characteristics.

Selection Notes

Select this component when a single-wire interface is required to minimize PCB trace count. Choose the Automotive grade ('E') variant if operation exceeds standard industrial temperatures. Verify that the 16-byte page buffer size aligns with application write patterns to optimize performance.

Part Context

This part belongs to the 11LC161 family of 16 Kbit Serial Electrically Erasable PROMs. It shares architectural similarities with other members like the 11AA161 but differs in operating voltage ranges and temperature specifications. The family utilizes a common instruction set and communication protocol across various densities and packages.

Replacement Considerations

Substitutes must support the UNI/O protocol and match the 2048 x 8 organization. Compatible alternatives include other 11LC161 variants with different packages or temperature grades, provided the electrical characteristics meet system requirements.
