What are the key features of 11LC080-I/SN?

  • 8Kbit single-wire UNI/O serial EEPROM with 1024 x 8 organization, requiring only one I/O pin for communication to minimize microcontroller pin usage in low-pin-count designs
  • 1 MHz maximum clock frequency on the UNI/O interface enabling fast data transfers while maintaining compatibility with low-power microcontrollers at standard operating speeds
  • 1 million write/erase cycle endurance with 200-year data retention, providing long-term reliability for storing configuration, calibration, and user data in embedded systems
  • Lead-free, RoHS-compliant SOIC-8 package with 2.5V to 5.5V wide operating voltage range for compatibility with modern 3.3V and legacy 5V microcontroller systems

What is 11LC080-I/SN used for?

The 11LC080-I/SN is ideal for embedded systems requiring non-volatile storage of configuration parameters, calibration coefficients, and small data tables with minimal I/O pin usage. Its single-wire UNI/O interface makes it particularly attractive in pin-constrained microcontroller designs such as IoT sensor nodes, smart appliance controls, and wearable electronics. The device is also used in industrial equipment for storing device identification, revision history, and operating logs where the standard SOIC-8 footprint simplifies PCB layout.

Frequently Asked Questions

What is the memory capacity and organization of the 11LC080-I/SN?

The 11LC080-I/SN is an 8Kbit EEPROM organized as 1024 words of 8 bits each (1024 x 8). It uses Microchip's UNI/O single-wire serial interface with a maximum clock frequency of 1 MHz, significantly simplifying wiring by requiring only one signal line plus power and ground.

What interface protocol does the 11LC080-I/SN use and how does it differ from I2C or SPI?

The 11LC080-I/SN uses Microchip's UNI/O protocol, a single-wire half-duplex serial interface that requires only one I/O line for bidirectional communication, compared to I2C's two lines (SDA, SCL) or SPI's four lines. This makes it ideal for systems with very limited GPIO availability, such as small 8-pin microcontrollers.

What is the endurance and data retention of the 11LC080-I/SN?

The 11LC080-I/SN supports a minimum of 1 million write/erase cycles per byte location and provides a minimum data retention period of 200 years. These specifications ensure the device is suitable for applications requiring frequent data updates as well as long-term archival storage.

What voltage range and package options are available for the 11LC080-I/SN?

The 11LC080-I/SN operates across a wide voltage range of 2.5V to 5.5V, making it compatible with 3.3V and 5V embedded systems. It is packaged in an industry-standard SOIC-8 (8-pin Small Outline IC) form factor, which is widely supported by PCB CAD libraries and automated assembly equipment.

What are the typical applications and alternatives for the 11LC080-I/SN?

Common applications include storing device configuration, user settings, serial numbers, and calibration data in space-constrained embedded designs. Compatible alternatives include the Microchip 11AA080 (extended temperature variant), the 11LC160 (16Kbit, same interface), and standard I2C EEPROMs such as the 24LC08 for designs tolerant of the two-wire I2C interface.
