11LC160T-I/TT

Overview

The Microchip Technology 11LC160T-I/TT is a 16 Kbit serial electrically erasable programmable read-only memory (EEPROM) utilizing the UNI/O single-wire interface. It features a 2,048 x 8 bit organization and operates within a voltage range of 2.5 V to 5.5 V. The device supports a maximum clock frequency of 100 kHz and includes a 16-byte page-write buffer. It is housed in a SOT-23-3 package and rated for industrial temperatures from -40°C to +85°C.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding.
• Includes built-in write protection with power-on/off data protection circuitry and block write protection options.
• Features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.
• Provides high reliability with one million erase/write cycles endurance and over 200 years of data retention.

Applications

• Microcontroller system configuration storage
• Calibration data retention in embedded devices
• Low-pin-count sensor data logging

Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm the device address code corresponds to the intended bus topology. Ensure compatibility with the host controller's UNI/O driver implementation before finalizing procurement orders.

Selection Notes

Select this component when a single-wire interface is required to minimize pin count on the host microcontroller. Choose this part for applications needing robust write protection mechanisms and long-term data retention without requiring complex multi-wire protocols like SPI or I2C.

Part Context

This device belongs to the 11LCXXX family of serial EEPROMs from Microchip Technology. It shares architectural similarities with other members of the 11XX series but is distinguished by its 16 Kbit density and specific voltage operating range suitable for standard logic levels.

Replacement Considerations

The 11AA160T-I/TT serves as a compatible alternative within the same family, offering identical functionality but supporting a lower minimum supply voltage of 1.8 V compared to the 2.5 V minimum of the 11LC160T-I/TT.
