ISL22316WMUEP ® Single Digitally Controlled Potentiometer (XDCP™) Data Sheet December 17, 2007 FN6622.0 Low Noise, Low Power I2C® Bus, 128 Taps Features The ISL22316WMUEP integrates a single digitally controlled potentiometer (DCP) and non-volatile memory on a monolithic CMOS integrated circuit. • Specifications per DSCC VID V62/08603-01XB The digitally controlled potentiometer is implemented with a combination of resistor elements and CMOS switches. The position of the wipers are controlled by the user through the I2C 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 Supply Center in Columbus (DSCC). “Hot-links” to the applicable VID and other supporting application information are provided on our website. • Full Mil-Temp Electrical Performance from -55°C to +125°C • 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 • I2C Serial Interface - Two Address Pins, Up To Four Devices/Bus • Non-volatile Storage of Wiper Position • Wiper Resistance: 70Ω Typical @ 3.3V • Shutdown Mode • Shutdown Current 5µA Max • Power Supply: 2.7V to 5.5V • 10kΩ Total Resistance Pinout SCL 1 10 VCC SDA 2 9 RH A1 3 8 RW • High Reliability - Endurance: 1,000,000 Data Changes Per Bit Per Register - Register Data Retention: - 10 years @ T ≤ +125°C - 15 years @ T ≤ +90°C - 50 years @ T ≤ +55°C A0 4 7 RL • 10 Ld MSOP SHDN 5 6 GND ISL22316WMUEP (10 LD MSOP) TOP VIEW Ordering Information VENDOR PART NUMBER (Notes 1, 2) ISL22316WMUEP VENDOR ITEM DRAWING PART MARKING V62/08603-01XB 2316M RESISTANCE OPTION (kΩ) 10 TEMP.
