Microchip Technology’s new UNI/O serial EEPROM uses only ONE connection
to the host microcontroller. This compares to two or three pins for I2C™ and
three to six pins for Microwire or SPI buses. This new, flexible bus offers
advanced features like a status register and write protection on demand,
along with all I/O, data and command functions through a single pin.
Simplify designs & reduce system cost
