ISL22316WM single digitally c ontrolled potentiometer (xdcp?) low noise, low power i 2 c ? bus, 128 taps the ISL22316WMuep integrates a single digitally controlled potentiometer (dcp) and non-volatile memory on a monolithic cmos integrated circuit. the digitally controlled potentio meter is implemented with a combination of resistor el ements and cmos switches. the position of the wipers are contro lled by the user through the i 2 c bus interface. the potentiometer has an associated volatile wiper register (wr) and a non-volatile initial value register (ivr) that can be directly written to and read by the user. the contents of the wr controls the position of the wiper. at power-up, the device recalls the contents of the dcp?s ivr to the wr. the dcp can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including control, parameter adjustments and signal processing. device information the specifications for an enhanced product (ep) device are defined in a vendor item drawing (vid), which is controlled by the defense logistics agency (dla). ?hot-links? to the applicable vid and other supporting application information are provided on our website. features ? specifications per dscc vid v62/08603-01xb ? full mil-temp electrical perf ormance from -55c to +125c ? controlled baseline with one wafer fabrication site and one assembly/test site ? full homogeneous lot processing in wafer fab ? no combination of wafer fabrication lots in assembly ? full traceability through assembly and test by date/trace code assignment ? enhanced process change notification ? enhanced obsolescence management ? eliminates need for up-screening a cots component ? 128 resistor taps ?i 2 c serial interface - two address pins, up to four devices/bus ? non-volatile storage of wiper position ? wiper resistance: 70 typical @ 3.3v ? shutdown mode ? shutdown current 5a max ? power supply: 2.7v to 5.5v ?10k total resistance ? high reliability - endurance: 1,000,000 data changes per bit per register - register data retention: - 10 years @ t +125c - 15 years @ t +90c - 50 years @ t +55c ?10 ld msop pinout ISL22316WMuep (10 ld msop) top view 1 2 3 4 5 6 10 9 8 7 sda shdn a0 a1 v cc scl gnd r l r w r h ordering information vendor part number (notes 1, 2) vendor item drawing part marking resistance option (k ) temp. range (c) package pkg. dwg. # ISL22316WMuep v62/08603-01xb 2316m 10 -55 to +125 10 ld msop m10.118 notes: 1. add ?-tk? suffix for tape and reel. please refer to tb347 for details on reel specifications. 2. devices must be procured to the vendor part number. data sheet november 11, 2011
