The DS3901 is a triple, 8-bit nonvolatile (NV) variable resistor. Each of the resistors has two setting registers, which are selectable by software or by pin configuration. The selected register determines the value of the variable resistor. Additionally, all three resistors have a high-impedance setting. Resistor R0 has the additional flexibility of allowin.
an optional password-protection scheme that allows the protection of sensitive data.
