UNI/O™ EEPROM Memory UNI/O™ Serial EEPROMs Single I/O Bus Interface www.microchip.
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 I2C™, and three to six pins for Microwire or SPI buses.
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 Bu
Designing with the UNI/O Serial EEPROM Resources to help you get started quickly ... MPLAB® Starter Kit for Serial Memory Products (Part Number DV243003) Total Endurance™ Software Microchip’s Total Endurance Software provides you with unprecedented visibility into Serial EEPROM based applications. Describe your system to an advanced mathematical model (with a friendly human interface), and it will predict the performance and reliability of the Serial EEPROM within that environment.
