Product details
Overview
X9315WMIZ-2.7 from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 31-element resistor array with 32 wiper tap positions, nonvolatile wiper position storage, and 2.7V–5.5V single-supply operation. It functions as a three-terminal voltage divider or two-terminal variable resistor in analog signal conditioning circuits requiring stable, repeatable resistance adjustment under industrial temperature conditions (–40°C to +85°C).
For engineers reviewing the X9315WMIZ-2.7 datasheet, X9315WMIZ-2.7 pinout, X9315WMIZ-2.7 application, or X9315WMIZ-2.7 equivalent, this device supports low-power (5µA standby), high-reliability (100k endurance cycles, 100-year data retention), and temperature-compensated (±300 ppm/°C RTOTAL) analog trimming in embedded control and sensor interface designs.
Technical Context
The X9315WMIZ-2.7 uses a 5-bit up/down counter driving a decoder that selects one of 32 wiper positions across a monolithic 31-resistor ladder. Wiper position is stored in nonvolatile memory upon CS↑ while INC = HIGH, enabling power-up recall without external configuration.
Its 3-wire serial interface (CS, U/D, INC) operates with make-before-break switching, ensuring continuity during wiper transitions. Terminal voltages are rail-to-rail (0 to VCC), and wiper resistance is 400–1000Ω at 2.7V, supporting ≤±3.75mA wiper current per specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ ±20% end-to-end resistance - defines full-scale analog range for voltage division or current limiting |
| VCC Range | 2.7V to 5.5V - enables direct compatibility with 3.3V and 5V logic systems without level shifting |
| Wiper Positions | 32 discrete taps - provides 3.125% resolution per step for precise analog gain or offset calibration |
| Standby Current | 5µA max - allows integration into battery-powered or always-on sensor nodes with minimal quiescent drain |
| Temp Range | –40°C to +85°C - qualified for industrial-grade operation in motor controls, HVAC, and instrumentation |
| Nonvolatile Store | 100,000 write cycles / 100-year retention - eliminates need for external EEPROM or MCU-based state backup |
| Wiper Resistance | 400–1000Ω at 2.7V - impacts loading error in high-impedance feedback paths; must be factored into precision divider design |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS-compliant), JEDEC MO-187AA footprint (M8.118), body dimensions 3.0mm × 3.0mm × 0.85mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply voltage input | Primary power rail; must be ≥ VH, VL, VW; powers internal logic and resistor array |
| VSS | Ground reference | Return path for all internal circuitry and wiper current; must be connected before applying signals |
| RH/VH | High terminal | Fixed end of resistor array; voltage range 0 to VCC; serves as top rail in voltage divider configurations |
| RL/VL | Low terminal | Fixed end of resistor array; voltage range 0 to VCC; serves as bottom rail or ground-referenced node |
| RW/VW | Wiper terminal | Movable tap point; output voltage varies linearly with position; series resistance affects loading in high-Z circuits |
| CS | Chip select | Active-low enable; initiates wiper movement when LOW; triggers nonvolatile store on rising edge with INC = HIGH |
| U/D | Up/down direction control | Logic level determines wiper increment/decrement direction during INC toggling; latched on CS assertion |
| INC | Increment clock input | Negative-edge-triggered; advances wiper one position per valid edge; timing min. 4µs cycle required |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer | Eliminates mechanical wear, vibration sensitivity, and contact noise inherent in rotary pots |
| 3-wire serial interface | Requires only three GPIOs - no SPI/I²C peripheral needed; simplifies MCU resource allocation |
| Nonvolatile wiper storage | Recalls last-set position at power-up - ensures consistent startup behavior without host initialization |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift - maintains ratio accuracy across industrial ambient ranges |
| Low-power CMOS design | 80µA active current at 2.7V - suitable for energy-constrained analog front-ends and portable instruments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5175BRMZ-10 | 256-tap I²C interface; 10kΩ; 2.7–5.5V; 5ppm/°C tempco; no nonvolatile store by default (requires external command) | Higher resolution but requires I²C bus and explicit store command; better tempco but lower endurance (50k cycles) | Select AD5175BRMZ-10 when finer resolution and tighter tempco outweigh need for automatic power-up recall. |
| MCP41010-I/P | 256-tap SPI interface; 10kΩ; 2.7–5.5V; volatile wiper register only; no nonvolatile memory | Requires continuous MCU supervision; no power-loss recovery; higher resolution but no auto-recall | Select MCP41010-I/P only if system firmware guarantees wiper reinitialization at boot and SPI resources are available. |
Compared with AD5175BRMZ-10 and MCP41010-I/P, the X9315WMIZ-2.7 uniquely combines automatic nonvolatile recall, industrial temperature rating, and minimal 3-wire interface-making it optimal for unattended or safety-critical trimming where power loss resilience is mandatory.

FAQ
What is the maximum wiper current rating for the X9315WMIZ-2.7?
The X9315WMIZ-2.7 supports a maximum wiper current of ±3.75mA under recommended operating conditions. This limit ensures safe operation within the 10mW total power rating and prevents thermal drift or long-term degradation of the resistor array. Exceeding this current may cause irreversible resistance shift or reduced endurance.
Does the X9315WMIZ-2.7 retain its wiper position after power cycling?
Yes, the X9315WMIZ-2.7 automatically recalls the last-stored wiper position from nonvolatile memory upon power-up. The position is saved when CS transitions HIGH while INC is held HIGH, and retained for up to 100 years - eliminating the need for host MCU initialization or external memory.
Can the X9315WMIZ-2.7 operate from a 3.3V supply?
Yes, the X9315WMIZ-2.7 is fully specified for 2.7V to 5.5V operation, making it compatible with standard 3.3V logic systems. At 3.3V, active current remains ≤80µA, wiper resistance is ~300–700Ω, and all timing parameters (e.g., 4µs INC cycle) remain valid per datasheet limits.
What package type is used for the X9315WMIZ-2.7?
The X9315WMIZ-2.7 uses an 8-lead MSOP package (JEDEC MO-187AA, drawing M8.118), Pb-free and RoHS-compliant. Its 3.0mm × 3.0mm footprint supports high-density PCB layouts and is compatible with standard reflow profiles including Pb-free soldering.
How does the X9315WMIZ-2.7 handle wiper movement during rapid INC toggling?
The X9315WMIZ-2.7 employs make-before-break switching during wiper transitions. When multiple INC edges occur rapidly, intermediate taps connect briefly to RW/VW - causing temporary reduction in effective RTOTAL. Designers must allow ≥5µs settling (tIW) after final INC edge before sampling VW to ensure stable output.
