Product details
Overview
X9313WPI from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 32-tap linear resistor array with nonvolatile wiper position storage, 3-wire serial interface (CS/U/D/INC), ±VCC terminal voltage range, and 10kΩ end-to-end resistance - used for precision analog trimming in power supply feedback loops, sensor calibration circuits, and programmable gain amplifiers.
For engineers reviewing the X9313WPI datasheet, X9313WPI pinout, X9313WPI application, or X9313WPI equivalent, key selection criteria include its PDIP-8 package compatibility with through-hole wave soldering, -40°C to +85°C industrial temperature rating, 100-year data retention, and make-before-break wiper switching behavior critical for glitch-free analog adjustments.
Technical Context
The X9313WPI integrates a 31-element resistor ladder, 5-bit up/down counter, nonvolatile EEPROM for wiper position storage, and CMOS control logic. Its wiper movement is edge-triggered on INC with direction set by U/D, and store-to-memory occurs on CS↑ while INC = HIGH.
Operation supports both three-terminal potentiometer (RH/VH–RW/VW–RL/VL) and two-terminal variable resistor configurations. Terminal voltage tolerance of ±VCC and wiper resistance of 40Ω (typ.) at VCC = 5V enable direct interfacing with op-amps and voltage references without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance (RTOTAL) | 10kΩ ±20% - sets full-scale adjustment range for gain/voltage division networks |
| Wiper positions | 32 discrete taps - provides 3.125% resolution per step across full resistance range |
| Terminal voltage range | ±VCC - allows bidirectional signal handling and rail-to-rail operation with single-supply systems |
| Nonvolatile memory endurance | 100,000 write cycles - supports field recalibration over product lifetime |
| Power supply range | 4.5V to 5.5V - compatible with standard 5V logic and analog rails |
| Operating temperature | -40°C to +85°C - qualified for industrial-grade embedded control environments |
| Wiper resistance | 40Ω (typ.) at VCC = 5V - minimizes insertion error in low-impedance feedback paths |
Pinout & Package
Package: 8-pin PDIP (Plastic Dual-In-Line Package), Pb-free, RoHS compliant, intended for through-hole wave solder processing only (not reflow-compatible).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Provides power to internal logic and resistor array; must be stabilized before CS/INC transitions |
| VSS | Ground reference | Common return path for all digital and analog functions; requires low-impedance connection |
| RH/VH | High terminal | Fixed end of resistor array; voltage polarity relative to wiper depends on U/D state, not absolute potential |
| RL/VL | Low terminal | Fixed opposite end of resistor array; forms complete resistive path with RH/VH and RW/VW |
| RW/VW | Wiper output | Movable tap point; series resistance ≤100Ω ensures minimal loading in precision divider applications |
| CS | Chip select | Active-low enable; stores wiper position on rising edge when INC = HIGH; places device in standby when HIGH |
| U/D | Direction control | Sets increment/decrement direction for wiper movement; stable during CS = LOW for multi-step adjustment |
| INC | Increment clock | Negative-edge triggered; advances wiper one tap per valid edge; timing tCYC ≥ 2µs required |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Retains last-set tap value across power cycles - eliminates startup calibration routines in embedded systems |
| Make-before-break wiper switching | Prevents open-circuit transients during tap changes - essential for stable feedback loop operation |
| Temperature-compensated resistor array | ±300 ppm/°C RTOTAL drift - maintains trim accuracy over industrial temperature range |
| 3-wire serial interface | No clock or data lines beyond CS/U/D/INC - reduces MCU GPIO count and simplifies firmware |
| Pb-free PDIP packaging | RoHS-compliant through-hole mounting - supports legacy board assembly and repair workflows |
Applications
| Power Supply Feedback Trimming | Sensor Offset Calibration |
|---|---|
Use Scenario: Adjusting output voltage of adjustable DC-DC converters (e.g., LM317, LT308x) via feedback resistor divider. IC Role / Device Role / Timing Role: Replaces mechanical trimpot in voltage-setting network; wiper position determines VOUT = VREF × (1 + RH/RW). Use Value: Enables remote or automated recalibration without hardware access; 10kΩ RTOTAL matches typical feedback impedance for <1% output error. | Use Scenario: Nulling thermal drift in bridge-based pressure or load-cell sensors using instrumentation amplifier offset networks. IC Role / Device Role / Timing Role: Two-terminal variable resistor in op-amp summing junction to inject compensating current. Use Value: 32-tap resolution achieves sub-mV nulling precision; nonvolatile storage retains calibration after sensor replacement or field maintenance. |
| Programmable Gain Amplifier | Audio Channel Balance Control |
Use Scenario: Setting closed-loop gain of noninverting op-amp (e.g., TL072, OP-07) by varying feedback-to-ground resistance ratio. IC Role / Device Role / Timing Role: Three-terminal potentiometer where RH/VH connects to op-amp output, RW/VW to inverting input, RL/VL to ground. Use Value: ±VCC terminal rating allows use with dual-supply op-amps; 40Ω wiper resistance avoids gain error in high-Z feedback paths. | Use Scenario: Matching left/right channel levels in analog audio distribution systems using dual op-amp buffers. IC Role / Device Role / Timing Role: Dual independent trimming element - one X9313WPI per channel, synchronized via shared CS/U/D/INC bus. Use Value: Identical 10kΩ RTOTAL ensures matched channel response; PDIP package enables manual bench adjustment during production test. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ10 | I²C interface, dual-channel, 256-tap resolution, 10kΩ RTOTAL, VDD = 2.7–5.5V | Requires I²C master; higher resolution but no nonvolatile storage per channel | Choose for multi-channel systems needing finer granularity and digital bus integration |
| MCP41010-I/P | SPI interface, single-channel, 257-tap resolution, 10kΩ RTOTAL, VDD = 2.7–5.5V, volatile wiper register | No EEPROM - loses setting on power loss; requires external microcontroller to reload | Choose when cost-sensitive designs can tolerate recalibration at boot or accept external NVM management |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313WPI offers deterministic power-up behavior without host intervention, simpler 3-wire control timing, and proven industrial temperature reliability - making it optimal for standalone analog trimming where EEPROM persistence and minimal MCU overhead are critical.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313WPI?
The X9313WPI supports a maximum differential voltage ΔV = |VH − VL| of 10V under recommended operating conditions. This limit applies regardless of VCC level and ensures safe operation of the internal resistor array and wiper switches. Exceeding 10V risks irreversible damage to the thin-film elements and is strictly prohibited per Absolute Maximum Ratings.
Does X9313WPI retain its wiper position after power cycling?
Yes, X9313WPI stores the last wiper position in nonvolatile EEPROM memory and automatically recalls it upon power-up. This behavior is guaranteed for 100 years of data retention and survives ≥100,000 store cycles. No external controller or initialization sequence is required - the device powers up in the exact state it was left in.
Can X9313WPI be used with a 3.3V microcontroller interface?
No - X9313WPI requires VCC = 4.5V to 5.5V and is not 3.3V-compatible. Its CS, U/D, and INC inputs have VIH = 2.0V minimum and VIL = +0.8V maximum, but the internal logic and resistor array are specified only for 5V operation. Driving inputs from a 3.3V MCU may result in unreliable wiper movement or failed store operations.
Is the X9313WPI PDIP package suitable for reflow soldering?
No - the X9313WPI in PDIP package (MDP0031) is rated for through-hole wave solder processing only. Reflow soldering is explicitly prohibited per datasheet Note ***, as Pb-free PDIP bodies are not thermally rated for peak reflow temperatures. Use SOIC or MSOP variants (e.g., X9313WSIZ) for surface-mount reflow assembly.
What is the wiper resistance specification for X9313WPI at 5V supply?
The wiper resistance (RW) for X9313WPI is specified as 40Ω (typical) and 100Ω (maximum) when VCC = 5V and wiper current is set to IW = (VH − VL)/RTOTAL. This low on-resistance minimizes insertion error in precision voltage dividers and ensures predictable gain in op-amp feedback networks.
