Description  
VSS  
The MCP4021/2/3/4 devices are non-volatile, 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 tech-  
nology, which allows application-specific calibration  
settings to be secured in the EEPROM without  
requiring the use of an additional write-protect pin.
