Need more microcontroller pins for new features? Want to stay with a low pin-count microcontroller rather than switching to a more expensive one? Microchip’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, proprietary bus offers advanced features like a status register and write protection on demand, along with all I/O, memory array and command functions through a single pin.
