Product details
Overview
X9313WSZT1 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 voltage reference and op-amp feedback networks.
For engineers reviewing the X9313WSZT1 datasheet, X9313WSZT1 pinout, X9313WSZT1 application, or X9313WSZT1 equivalent, key selection criteria include its 10kΩ RTOTAL tolerance (±20%), 40Ω typical wiper resistance at 5V, 100-year data retention, -40°C to +85°C industrial temperature range, and SOIC-8 package compatibility with standard reflow profiles.
Technical Context
The X9313WSZT1 uses a 5-bit up/down counter driving a 31-element resistor ladder with make-before-break wiper switching, enabling precise tap-by-tap adjustment without open-circuit interruption. Its control logic responds to negative-edge-triggered INC pulses while U/D sets direction and CS enables operation or initiates nonvolatile store.
Wiper position is retained in EEPROM-style nonvolatile memory and automatically recalled at power-up; the device operates at VCC = 4.5–5.5V with active current ≤3mA and standby current ≤500µA. Terminal voltages support ±VCC swing, allowing bidirectional signal handling in AC-coupled or dual-supply configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance (RTOTAL) | 10kΩ ±20% - defines full-scale analog adjustment range and sets minimum load impedance for stable divider operation. |
| Wiper resistance | 40Ω typical at VCC = 5V - contributes directly to output impedance error in voltage divider configurations. |
| Terminal voltage range | −VCC to +VCC - enables use in bipolar signal paths and rail-to-rail input/output stages without external level-shifting. |
| Nonvolatile retention | 100 years - guarantees factory-set or user-trimmed calibration values persist across product lifetime without backup power. |
| Endurance | 100,000 wiper position changes per bit - supports repeated field calibration or dynamic parameter tuning in embedded systems. |
| Supply voltage (VCC) | 4.5V to 5.5V - matches standard 5V logic and analog supply rails, eliminating need for dedicated low-voltage regulators. |
| Operating temperature | −40°C to +85°C - qualified for industrial environments including motor drives, instrumentation, and outdoor electronics. |
Pinout & Package
Package: 8-lead SOIC (Pb-free, RoHS compliant, JEDEC MS-012-AA compliant, M8.15 outline).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Provides power for internal logic and resistor array; must be stabilized before CS activation to prevent spurious wiper movement. |
| VSS | Ground reference | Common return path for all digital control signals and analog terminals; requires low-impedance connection to minimize noise coupling. |
| RH/VH | High terminal | Fixed end of resistor array; functions as upper voltage rail in three-terminal potentiometer mode or one end of two-terminal variable resistor. |
| RL/VL | Low terminal | Fixed end of resistor array; serves as lower voltage rail or second terminal in variable resistor configuration; polarity relative to RH/VH depends on U/D state. |
| RW/VW | Wiper terminal | Movable contact point delivering tapped voltage or resistance; series resistance (40Ω typ.) affects accuracy in high-gain feedback loops. |
| CS | Chip select | Active-low enable; falling edge activates control logic; rising edge with INC = HIGH triggers nonvolatile store of current wiper position. |
| U/D | Up/down direction control | Static logic level defining wiper increment/decrement direction during subsequent INC transitions; may be changed dynamically while CS = LOW. |
| INC | Increment clock input | Negative-edge-triggered; each valid pulse moves wiper one tap; timing requires tIL ≥1µs and tIH ≥1µs per datasheet AC specs. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, vibration sensitivity, and contact bounce - critical for long-life industrial control panels and sealed enclosures. |
| 3-wire serial interface | Requires only three GPIO lines (CS/U/D/INC) - reduces MCU pin count vs. I²C/SPI alternatives and avoids address conflict or bus arbitration overhead. |
| 32-tap linear resolution | 3.125% step size (1/31) - provides sufficient granularity for audio volume control, sensor offset trimming, and gain calibration without overspecifying MCU resolution. |
| Temperature-compensated resistor array | ±300 ppm/°C RTOTAL drift - maintains ratio accuracy across industrial temperature range, essential for stable reference voltages in ADC front-ends. |
| Make-before-break wiper switching | Prevents open-circuit condition during tap transitions - avoids momentary signal dropout in active filter or amplifier feedback paths. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5171BRMZ-10 | I²C interface, 64-tap resolution, 10kΩ RTOTAL, ±30% tolerance, 2.7–5.5V supply | Requires I²C host; higher resolution but looser resistance tolerance affects absolute voltage accuracy | Preferred when system already uses I²C and finer adjustment granularity is needed over absolute accuracy. |
| MCP41010-I/P | SPITM interface, 257-tap resolution, 10kΩ RTOTAL, ±20% tolerance, 2.7–5.5V supply, volatile wiper register | No nonvolatile storage - wiper resets to mid-scale on power-up; requires external MCU initialization | Chosen where frequent dynamic reconfiguration outweighs need for power-loss retention, and SPI infrastructure exists. |
Compared with X9313WSZT1, AD5171BRMZ-10 offers higher resolution and I²C simplicity but sacrifices guaranteed power-up state and tighter RTOTAL tolerance; MCP41010-I/P delivers superior resolution and faster interface speed but lacks nonvolatile recall, demanding firmware intervention for deterministic startup behavior.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313WSZT1?
The X9313WSZT1 supports ΔV = |VH − VL| up to 10V, as specified for the "W" variant in the Absolute Maximum Ratings table. This limit ensures safe operation of the internal resistor array and switching elements under full-scale voltage divider conditions without degradation or latch-up risk.
Does X9313WSZT1 retain its wiper position after power cycling?
Yes, X9313WSZT1 stores the last wiper position in nonvolatile memory and automatically recalls it upon power-up. This behavior is guaranteed for 100 years and eliminates the need for MCU-initiated restoration, making X9313WSZT1 ideal for unattended or safety-critical calibration retention.
Can X9313WSZT1 operate with a 3.3V supply?
No, X9313WSZT1 is rated for VCC = 4.5V to 5.5V only. It is not compatible with 3.3V logic systems. For 3V operation, consider the X9313-3 variants (e.g., X9313WSZ-3T1), which specify 3V to 5.5V supply range and are functionally identical except for supply voltage tolerance.
What is the wiper resistance specification for X9313WSZT1 and how does it affect circuit performance?
X9313WSZT1 has a typical wiper resistance of 40Ω at VCC = 5V (max 100Ω). This series resistance introduces gain error in op-amp feedback networks and voltage division inaccuracies proportional to load current; designers must account for it in precision applications where <0.1% error is required.
Is X9313WSZT1 RoHS compliant and what packaging does it use?
Yes, X9313WSZT1 is RoHS compliant and supplied in an 8-lead SOIC package (M8.15 outline) with 100% matte tin (e3) termination finish, qualified for both SnPb and Pb-free reflow soldering per IPC/JEDEC J-STD-020 standards.
