Frequently Asked Questions
What interface does the 11LC020-I/SN use, and how many I/O pins does it require?
The 11LC020-I/SN uses Microchip's UNI/O single-wire serial interface, requiring only 1 data I/O pin plus VCC and GND. This minimizes pin usage on the host microcontroller and simplifies PCB routing compared to 2-wire I2C or 4-wire SPI EEPROMs, making it ideal for pin-constrained designs.
What supply voltage range and maximum clock frequency does the 11LC020-I/SN support?
The 11LC020-I/SN operates from 2.5 V to 5.5 V supply voltage and supports a maximum UNI/O clock frequency of 1 MHz. This broad voltage range allows direct interfacing with 3.3 V and 5 V microcontrollers without level shifters in most designs.
How does the 11LC020-I/SN compare to a standard I2C EEPROM of the same density for a battery-powered sensor application?
For a battery-powered sensor storing 256 bytes of calibration data, the 11LC020-I/SN saves at least 1 PCB pin versus a 2-wire I2C device and is available in a compact SOIC-8 package. It endures 1,000,000 write/erase cycles with 200-year data retention, providing the same reliability with a simpler wiring scheme.
