Description

The X93256WV14I-2.7 is one member of the X93256 family which is designed as the dual digitally controlled potentiometer (XDCP) that consists of two resistor arrays, wiper switches, a control section, and nonvolatile memory. Also this device is connected as a three-terminal variable resistor and can be used in bias and gain control and LCD Contrast Adjustment applications.

Features of the X93256WV14I-2.7 are:(1)Dual solid-state potentiometers; (2)Individual Up/Down interfaces; (3)32 wiper tap points per potentiometer - wiper position stored in nonvolatile memory and recalled on power-up; (4)31 resistive elements per potentiometer: temperature compensated, maximum resistance tolerance of +/-25% and terminal voltage, 0 to VCC; (5)Low power CMOS: Vcc = 2.7 V - 5.5 V, active current, 200uA typical per potentiometer, and standby current, 4uA max per potentiometer; (6)High reliability: endurance 200,000 data changes per bit, register data retention, 100 years; (7)RTOTAL value = 12.5k, 50k; (8)Packages: 4-lead TSSOP.

The absolute maximum ratings of the X93256WV14I-2.7 can be summarized as:(1)Temperature under bias: -65°C to +135°C;(2)Storage temperature: -65°C to +150°C;(3)Voltage on CS, INC, U/D, RH, RL and Vcc with respect to Vss: -1 V to +6.5 V;(4)Lead temperature (soldering 10 seconds): 300°C;(5)Maximum reflow temperature (40 seconds): 240°C;(6)Maximum resistor current: 2 mA.

The electrical characteristics of X93256WV14I-2.7 can be summarized as:(1)VCC active current (Increment): 50 to 250 A;(2)VCC active current (Store): 600 A;(3)Standby supply current: 1 A;(4)CS input leakage current: ±1 A;(5)INC, U/D input leakage current: ±1 A.
