11LC010-I/SN

Overview

The Microchip Technology 11LC010-I/SN is a 1Kbit serial EEPROM utilizing the UNI/O single-wire interface. It features a 128 x 8 organization with a 16-byte page write buffer. Operating voltages range from 2.5V to 5.5V, supporting clock frequencies up to 100 kHz. The device includes Schmitt trigger inputs for noise suppression and output slope control to minimize ground bounce. It offers high reliability with 1 million erase/write cycles and data retention exceeding 200 years.

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.
• Includes built-in write protection mechanisms such as power-on/off data protection circuitry and a configurable block write protection feature.
• Features a STATUS register for monitoring write-in-progress status and managing the write enable latch state.

Applications

• Interfacing with microcontrollers requiring low-pin-count memory solutions
• Embedded systems needing non-volatile storage for configuration data
• Industrial applications operating within the industrial temperature range

Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the SOIC-8 package in official documentation. Confirm the 'I' suffix indicates the Industrial temperature range of -40°C to +85°C. Ensure the voltage range matches system requirements as this model supports 2.5V to 5.5V, unlike lower-voltage variants.

Selection Notes

Select this component when a single-wire interface is required to minimize PCB trace count. The 11LC010 provides sufficient density for small data sets. Consider the 16-byte page buffer for efficient writing operations. Verify compatibility with the master controller's ability to implement the UNI/O protocol timing and handshake sequences.

Part Context

This part belongs to the 11LCXXX family of serial EEPROMs from Microchip Technology. These devices are designed for applications requiring robust, low-power non-volatile memory with simplified interfacing. The family shares common architectural features including the UNI/O bus and similar command sets across different densities.

Replacement Considerations

Check for other parts within the 11LC010 series with different package options if physical footprint constraints change. Verify if lower voltage operation is needed, which would require switching to the 11AA010 variant.
