Key Features
- 2 Kbit (256×8) density with 1,000,000 write/erase cycle endurance for reliable non-volatile storage
- Single-wire UNI/O interface at up to 1 MHz reduces PCB pin count to an absolute minimum
- Ultra-compact TDFN-8 (2×3 mm) package ideal for space-constrained portable and wearable designs
Applications
The 11LC020T-I/MNY is used in portable consumer electronics, medical wearables, and IoT sensor nodes where a minimal pin count non-volatile memory is required for storing calibration data, configuration, or user settings. Its single-wire UNI/O interface and 2.5 V to 5.5 V supply range make it compatible with a wide variety of low-power microcontrollers. The TDFN-8 package allows designers to fit persistent storage into the tightest board footprints without sacrificing endurance or data integrity.

Frequently Asked Questions
How many write cycles does the 11LC020T-I/MNY EEPROM guarantee, and what is its data retention specification?
Microchip specifies a minimum of 1,000,000 write/erase cycles and a data retention of at least 200 years for the 11LC020T-I/MNY. These figures make it well suited for applications that frequently update small amounts of configuration or calibration data, such as sensor offset values stored by an embedded microcontroller running at 3.3 V.
What is the maximum clock frequency supported by the 11LC020T-I/MNY single-wire interface?
The 11LC020T-I/MNY supports a maximum UNI/O clock frequency of 1 MHz on its single data line. This allows fast byte-level reads and writes over a single PCB trace, reducing wiring complexity compared to I2C or SPI EEPROMs while still providing adequate throughput for storing 256 bytes of configuration data in under 2 ms.
What supply voltage range does the 11LC020T-I/MNY support, and how does it compare to standard 3.3 V microcontroller systems?
The 11LC020T-I/MNY operates from 2.5 V to 5.5 V, covering both 3.3 V and 5 V microcontroller environments without level-shifting hardware. This wide voltage tolerance makes it a convenient drop-in storage solution for PIC, AVR, and ARM Cortex-M systems, avoiding the extra BOM cost of a voltage translator in mixed-supply designs.
