Microchip’s new UNI/O serial EEPROM uses only ONE connection to the host microcontroller. This compares to two
or three pins for I
features like a status register and write protection on demand, along with all I/O, memory array and command
functions through a single pin.
UNI/O bus: First introduced on serial EEPROMs

Introducing the UNI/O EEPROM Family
hi
Want to stay with a low pin-count microcontroller rather than
2
C™, and three to six pins for Microwire or SPI buses. This new, proprietary bus offers advanced
