UNI/O® Serial EEPROM
The UNI/O® serial EEPROM is a SINGLE I/O EEPROM device that has been developed by Microchip Technology Inc. The EEPROM has been developed to work on the UNI/O® Bus, a propriety single I/O bus protocol, also developed by Microchip Technology Inc. The Bus combines the clock and data lines into a single bit stream using the Manchester Encoding technique. To find out more on the working of the bus and the device click here.
The UNI/O® Serial EEPROM family was designed keeping in mind the best features of the other Microchip EEPROM families namely the I2C, SPI and Microwire and has been optimized for embedded applications.. This single I/O EEPROM family has the advantage of using just ONE MCU I/O pin as opposed to at least 4 MCU I/O’s needed by the SPI, 4 I/O’s by the Microwire and at least 2 I/O’s by the I2C. This helps:
1. Increase system value by freeing up extra I/O’s for other applications.
2. Reduce system cost by shifting a smaller, lower pin count MCU.
3. Add memory to the MCU when the MCU is pin-limited.
4. Reduces board cost with fewer traces, ensuring more compact designs.
