Winbond Electronics Corporation WMS7170
The WMS7170 device can be configured as a two-terminal variable resistor or a three-terminal voltage divider without an output buffer, but the WMS7171 device, which has a built-in output buffer, can only be configured as a three-terminal voltage divider. Both devices can be used in a wide variety of applications. The output of the potentiometer is determined by its wiper position, which varies linearly between its end terminals, RA/VA and RB/VB.| Part No. | WMS7170 |

GENERAL DESCRIPTION
The WMS7170/7171 is a single channel 100-tap non-volatile linear digital potentiometer available in 10KΩ, 50KΩ and 100KΩ resistance. The device consists of Up/Down serial interface, tap register, decoder, resistor array, wiper switches, NV memory and control logics. The wiper position, Rw/Vw, is controlled by Up/Down serial interface ( CS , INC and U/ D ) through the Tap Register (TR). In addition, the wiper position can also be stored into a non-volatile memory location (NVMEM0), which is then automatically recalled upon power up. 2.FEATURES
