UNI/O™ Serial EEPROMs
Single I/O Bus Interface
UNI/O™ EEPROM Memory
% \g www.microchip.com/UNIO
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 I
2
C™, 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.
Single I/O Interface
1-16 Kbit Memory Densities
1.8-5.5V Operating Voltage
10-100 KHz Operating Frequency
1 Million Erase/Write Cycles
