Key Features
- 8 Kbit (1024 × 8) serial EEPROM with 1-wire UNI/O interface, reducing GPIO pin count to a single line for I/O-constrained microcontrollers
- 1 million write/erase cycle endurance and 200-year minimum data retention for reliable non-volatile storage in long-life products
- SOT-23-3 package operating from 2.5 V to 5.5 V enabling integration into the smallest battery-powered and space-critical designs
Applications
The 11LC080T-I/TT is ideal for microcontroller-based systems needing configuration storage, calibration data, or small data logs where only 1 GPIO pin is available for memory access via the UNI/O single-wire protocol. Its wide 2.5 V to 5.5 V supply range and SOT-23-3 package make it a natural fit for wearables, smart labels, and IoT sensor nodes that demand minimal BOM and board area. The 1 million write cycle endurance also suits metering applications that update stored values frequently over a multi-year product lifespan.

Frequently Asked Questions
What is the memory density and organization of the 11LC080T-I/TT EEPROM?
The 11LC080T-I/TT provides 8 Kbits of EEPROM organized as 1024 × 8 bits, accessed over a single-wire UNI/O serial interface at up to 1 MHz clock, making it suitable for storing device configuration, calibration tables, and small firmware parameters.
How many write cycles can the 11LC080T-I/TT endure, and what is its data retention specification?
The 11LC080T-I/TT is rated for 1 million write/erase cycles per byte and guarantees a minimum 200-year data retention at 25°C, providing robust non-volatile storage longevity for industrial meters, smart sensors, and appliances that update stored values infrequently.
What supply voltage range does the 11LC080T-I/TT support, and what is the benefit for portable designs?
The device operates from 2.5 V to 5.5 V, covering 3 V coin cells, 3.3 V regulated rails, and 5 V logic systems without external level shifters. This flexibility simplifies the power-supply design in wearables and IoT nodes running on a single CR2032 or LR44 battery.
In what scenario is the 11LC080T-I/TT a better choice than a standard I2C EEPROM like 24LC08?
When a microcontroller has only 1 free GPIO pin — common in pin-limited 8-pin MCU designs — the 11LC080T-I/TT UNI/O single-wire protocol uses just that 1 line versus 2 lines (SDA + SCL) for I2C EEPROMs, freeing 1 additional pin for other peripherals such as a status LED or interrupt input.
