Description  
VSS  
The MCP4021/2/3/4 devices are nonvolatile, 6-bit  
digital potentiometers that can be configured as either a  
potentiometer or rheostat. The wiper setting is  
controlled through a simple Up/Down (U/D) serial  
interface.

These device’s implement Microchip’s WiperLock  
technology,  
which  
allows  
application-specific  
calibration settings to be secured in the EEPROM  
without requiring the use of an additional write-protect  
pin.
