Product details
Overview
X9511WSIZT1 from Intersil is a push-button controlled digital potentiometer (XDCP™) with 32 linear tap points, 10kΩ end-to-end resistance, ±5V terminal voltage range, and nonvolatile wiper position storage in EEPROM. It functions as a digitally adjustable resistor for analog signal conditioning in embedded trimming applications.
For engineers reviewing the X9511WSIZT1 datasheet, X9511WSIZT1 pinout, X9511WSIZT1 application, or X9511WSIZT1 equivalent, this device supports manual and AUTOSTORE®-enabled wiper positioning, slow/fast scan modes, and operates across -40°C to +85°C industrial temperature range in an 8-lead SOIC package.
Technical Context
The X9511WSIZT1 implements a 5-bit up/down counter driving a 32-position decoder to select taps across a 31-element resistor array. Wiper position is updated via debounced PU/PD inputs with 30–40ms internal debounce and automatic transition from slow (100–375ms/tap) to fast (25–90ms/tap) scan after 1 second of continuous button press.
Nonvolatile storage uses on-chip EEPROM with 100-year data retention and 100,000 store cycles. AUTOSTORE® triggers on VCC power-down when ASE is low; manual store occurs on ASE low-to-high edge. Terminal voltage tolerance is ±5V, and wiper current is limited to ±1mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 10kΩ ±20% - defines full-scale analog adjustment range and load interaction in voltage divider or rheostat configurations. |
| Wiper resolution | 323Ω per tap (10kΩ/31) - enables precise 3% resistance step control for calibration accuracy. |
| Terminal voltage range | ±5V referenced to VSS - supports bipolar analog signal handling without external level-shifting circuitry. |
| Supply current | 3mA max active, 100µA typical standby - minimizes system power draw during idle periods in battery-sensitive designs. |
| Wiper position retention | 100 years in EEPROM - eliminates need for backup power or external memory for power-cycle persistence. |
| Temperature coefficient | +300 ppm/°C typical (–40°C to +85°C) - ensures stable resistance value over industrial operating range. |
| Debounce time | 30–40ms typical - prevents false wiper moves from mechanical switch bounce without external RC filtering. |
Pinout & Package
Package: 8-lead SOIC (MDP0027), RoHS-compliant Pb-free with matte tin termination, rated for surface-mount reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VH | High terminal | Fixed end of resistor array; accepts –5V to +5V; polarity relative to wiper direction, not absolute voltage. |
| VL | Low terminal | Fixed end of resistor array; accepts –5V to +5V; polarity relative to wiper direction, not absolute voltage. |
| VW | Wiper output | Analog output node connected to selected tap; supports ±1mA wiper current; impedance ~40Ω typical. |
| VCC | Positive supply | 5V ±10% digital supply; powers logic, EEPROM, and internal pull-ups; no sequencing constraints with VH/VL. |
| VSS | Ground reference | Digital and analog common return; all voltages referenced to this node. |
| PU | Push-up input | Debounced active-low input; increments wiper position; internal pull-up eliminates external resistor. |
| PD | Push-down input | Debounced active-low input; decrements wiper position; internal pull-up eliminates external resistor. |
| ASE | AUTOSTORE enable | Active-low control: LOW enables auto-store on VCC drop; HIGH enables manual store on low-to-high edge. |
Key Features
| Feature | Design Value |
|---|---|
| Push-button interface | Direct connection to mechanical switches without external debouncing or logic - reduces BOM count and layout area. |
| AUTOSTORE® and manual store | Two nonvolatile store modes: automatic on power-down or user-triggered via ASE push - supports both fail-safe and intentional update use cases. |
| Slow/fast scan modes | Adaptive timing: 100–375ms/tap for precision adjustment, then 25–90ms/tap for rapid coarse tuning - improves usability across calibration tasks. |
| Temperature-compensated resistor array | ±20% end-to-end tolerance with +300 ppm/°C drift - maintains predictable linearity and repeatability across industrial temperature range. |
| 32-tap linear architecture | 31 resistive elements with decoded 5-bit counter - delivers deterministic, monotonic wiper movement without wraparound at extremes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5241BRMZ10 | I²C interface, 10kΩ, 64-tap, 2.7–5.5V supply; no push-button control or AUTOSTORE®. | Requires microcontroller host; suited for dynamic real-time adjustment rather than standalone manual trim. | Select when system already includes I²C bus and firmware support; avoid when push-button simplicity is required. |
| MCP41010-I/P | Serial SPI interface, 10kΩ, 257-tap, 2.7–5.5V; volatile wiper register, no EEPROM retention. | Needs external MCU and power-on initialization; lacks persistent setting recall without added circuitry. | Choose for higher resolution and faster digital updates; reject if power-cycle memory retention is mandatory. |
Compared with AD5241BRMZ10 and MCP41010-I/P, the X9511WSIZT1 uniquely delivers self-contained push-button operation, automatic power-down store, and industrial-temperature EEPROM retention - eliminating host processor dependency and ensuring calibration integrity without software or backup power.

FAQ
What is the maximum allowable voltage across VH and VL terminals for the X9511WSIZT1?
The X9511WSIZT1 specifies a maximum differential voltage ΔV = |VH − VL| of 10V, with each terminal rated for –5V to +5V relative to VSS. Exceeding these limits risks permanent damage to the resistor array or internal transfer gates. This rating holds across the full industrial temperature range (–40°C to +85°C) and is independent of VCC level.
Does the X9511WSIZT1 require external debounce circuitry for its PU and PD inputs?
No, the X9511WSIZT1 integrates internal debounce circuitry with a typical delay of 30–40ms, eliminating the need for external RC filters or microcontroller-based debouncing. Mechanical push buttons can connect directly to PU and PD, with internal pull-up resistors holding both inputs high until actively pulled low.
How does AUTOSTORE® functionality work on the X9511WSIZT1, and what conditions trigger it?
AUTOSTORE® on the X9511WSIZT1 activates automatically when the ASE pin is held low (VIL) and VCC drops below the AUTOSTORE threshold voltage (4V typical). A 2ms store cycle writes the current wiper position to EEPROM. Upon next power-up, the stored value is recalled - ensuring calibration persistence without user intervention or external control signals.
What is the wiper resistance specification for the X9511WSIZT1, and how does it affect circuit performance?
The X9511WSIZT1 has a typical wiper resistance of 40Ω, with a maximum of 100Ω. This low on-resistance minimizes loading error when used in voltage divider configurations and ensures accurate signal transfer in rheostat mode. At ±1mA maximum wiper current, voltage drop across the wiper remains under 100mV, preserving signal fidelity in precision analog paths.
Can the X9511WSIZT1 operate with a supply voltage other than 5V?
The X9511WSIZT1 is specified for 5V ±10% (4.5V to 5.5V) operation only. While absolute maximum ratings allow VCC up to +7V, functional operation outside the recommended range is not guaranteed - parameters like debounce timing, store reliability, and wiper linearity may degrade. Use only within 4.5V–5.5V for compliant design.
