What are the key features of 11LC020T-I/TT?
- Ultra-compact 3-pin SOT-23 package — the smallest possible EEPROM footprint for extreme space-constrained designs
- Single-wire UNI/O interface reduces pin count to an absolute minimum, freeing GPIO pins on the host microcontroller
- 1MHz clock frequency with 1 million write/erase cycle endurance and 200-year data retention
- 2.5V to 5.5V operating range compatible with a wide variety of 3.3V and 5V microcontroller systems
What is 11LC020T-I/TT used for?
The 11LC020T-I/TT is ideal for wearables, hearing aids, and miniaturized IoT sensor nodes that need to store a small amount of configuration or calibration data while minimizing PCB area and pin count. Its single-wire UNI/O interface and 3-pin SOT-23 package make it the go-to choice for designers retrofitting EEPROM storage onto existing boards with very limited available routing or GPIO pins.

Frequently Asked Questions
What serial interface does the 11LC020T-I/TT use?
The 11LC020T-I/TT uses Microchip's UNI/O single-wire serial interface, which communicates over a single bidirectional data line at up to 1MHz, eliminating the need for separate clock and data lines and reducing the host microcontroller pin count to just one GPIO.
What is the memory density of the 11LC020T-I/TT?
The device provides 2Kbits (2048 bits) of EEPROM organized as 256 bytes (256 x 8), which is sufficient for storing calibration coefficients, device serial numbers, user settings, or small lookup tables in compact embedded systems.
What is the write endurance of the 11LC020T-I/TT?
The 11LC020T-I/TT guarantees a minimum endurance of 1,000,000 write/erase cycles per byte, ensuring long operational life even in applications that update stored data frequently, such as event counters or adaptive calibration routines.
What package is the 11LC020T-I/TT available in?
It comes in a 3-pin SOT-23 (SOT-23-3, R-PDSO-G3) surface-mount package — one of the smallest standard IC packages available — making it perfect for designs where PCB real estate is extremely limited, such as in wearables or hearing aids.
Is the 11LC020T-I/TT RoHS compliant?
Yes, the 11LC020T-I/TT carries a Pb-free code and JESD-609 code e3, confirming it is manufactured without lead and is fully RoHS compliant, meeting environmental regulations for electronic components sold worldwide.
