UNI/OTM EEPROM Memory UNI/OTM Serial EEPROMs Single I/O Bus Interface www.microchip.com/UNIO Introducing the UNI/O EEPROM Family 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 I2CTM, 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. New Communications Standard Advanced Features UNI/O bus: First introduced on serial EEPROMs Manchester Communications - Clock and data in a single serial bit stream - Signal transition in the middle of bit period MCU establishes data rate EEPROM tracks data rate - Frequency and Phase Software Addressable Benefits A single I/O EEPROM can simplify your design and reduce system cost Free up pins on the MCU - Add a new feature to your application - Move to a smaller MCU Free up pins on your connector - Smaller connector = lower cost More compact design 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 Software Write Protect - 1/4, 1/2 or Full Array Status Register Set/Erase entire memory with a single command ESD Protection > 4 KV Noise Filtration Circuitry Packaging: 3-pin SOT-23 8-pin SOIC, MSOP & TDFN Temperature: Industrial (-40C to +85C) Extended (-40C to +125C) Get Started With a Simple Evaluation Use your existing hardware Use Microchip's software drivers UNI/O EEPROMs can fit in existing sockets - Pin-out similar to I2C and SPI EEPROMs - 8-pin packages share Vcc, Vss and Data Line UNI/O software drivers available for many popular microcontrollers New drivers coming Current EEPROM 8-lead Pin Outs i hi /UNIO www.microchip.com/UNIO Inside the UNI/O EEPROM Robust Interface * Current limited * Protection during short circuits and bus conflicts * Superior EMI performance EEPROM Memory * Density: 1K, 2K, 4K, 8K & 16K * Endurance > 1 Million Cycles * Data Retention > 200 Years CurrentLimited Slope Control HV Generator SCIO I/O Communication * Manchester encoding/ decoding * Synchronization circuitry * Software addressing I/O Control Logic Memory Control Logic X Dec EEPROM Array GND Page Latches Status Register Y Decoder Page Buffer * 16 byte page VCC Sense Amp.
