Product details
Overview
X9313ZMI from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 1kΩ end-to-end resistance, ±VCC terminal voltage range, and nonvolatile wiper position storage. It operates from 3V to 5.5V supply and functions as a three-terminal voltage divider or two-terminal variable resistor in precision analog trimming applications.
For engineers reviewing the X9313ZMI datasheet, X9313ZMI pinout, X9313ZMI application, or X9313ZMI equivalent, key selection criteria include its industrial temperature range (–40°C to +85°C), MSOP-8 package, 3-wire serial interface timing, wiper resistance (40Ω typ. at 5V), and guaranteed 100-year data retention in nonvolatile memory.
Technical Context
The X9313ZMI implements a 31-element resistor array with make-before-break wiper switching, enabling glitch-free tap transitions. Its 5-bit up/down counter drives a decoder that selects one of 32 wiper positions, with direction controlled by U/D and edge-triggered movement via INC.
Wiper position is stored in nonvolatile memory when CS rises while INC is HIGH, and automatically recalled at power-up. The device supports full-rail terminal voltages (–VCC to +VCC), has ±20% RTOTAL tolerance, and maintains ratiometric temperature coefficient of ±20 ppm/°C for stable voltage division accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 1kΩ - sets full-scale resistance for low-impedance analog adjustment circuits requiring minimal loading error |
| Tap count | 32 positions - provides 3% resolution per step (1/31 increment), sufficient for fine gain/offset calibration |
| VCC range | 3V to 5.5V - enables direct compatibility with both 3.3V and 5V logic and analog systems without level shifting |
| Terminal voltage range | –VCC to +VCC - allows bipolar signal handling (e.g., ±5V op-amp interfaces) without external clamping |
| Wiper resistance | 40Ω typical at VCC = 5V - ensures <0.5% error contribution in 1kΩ potentiometer configurations |
| Data retention | 100 years - guarantees factory-trimmed or user-calibrated settings persist across product lifetime without refresh |
| Endurance | 100,000 write cycles - supports repeated field recalibration in maintenance or adaptive control loops |
Pinout & Package
Package: 8-lead MSOP (Moisture Sensitivity Level 1, RoHS-compliant, Pb-free matte tin finish, JEDEC MO-187-AA compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RH/VH | High terminal | Fixed end of resistor array; referenced as "high" only relative to wiper direction-not absolute voltage polarity |
| RL/VL | Low terminal | Fixed end opposite RH/VH; forms complete resistive path with RH/VH and RW/VW |
| RW/VW | Wiper terminal | Movable contact point; output voltage varies linearly between VL and VH based on 32-position digital setting |
| VCC | Supply voltage | Power input (3V–5.5V); powers internal CMOS logic, memory, and switching network |
| VSS | Ground | Reference node for all digital inputs and analog terminals; must be low-impedance for noise immunity |
| CS | Chip select | Active-low enable; initiates communication and triggers nonvolatile store when rising edge occurs with INC = HIGH |
| U/D | Up/down control | Defines wiper movement direction during INC toggles; state may change dynamically while CS = LOW |
| INC | Increment input | Negative-edge-triggered; advances wiper one position per valid edge, with timing window tIW = 5µs max |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, vibration sensitivity, and contact bounce-critical for automotive and industrial environments |
| Nonvolatile wiper storage | Ensures repeatable startup behavior without host MCU initialization; reduces boot-time calibration overhead |
| 3-wire serial interface | Uses only CS, U/D, and INC-no clock or data lines required-minimizing GPIO usage and PCB routing complexity |
| Temperature-compensated array | ±20 ppm/°C ratiometric TC enables stable voltage division over –40°C to +85°C without external compensation |
| Make-before-break switching | Prevents open-circuit transients during wiper movement-essential for maintaining continuity in feedback paths |
Applications
| Audio Signal Level Control | Laser Diode Bias Adjustment |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5170BRMZ-10 | I²C interface, 10kΩ RTOTAL, 256 taps, 1.8V–5.5V supply | Higher resolution but larger step size (0.4% vs. 3%) and no ±VCC terminal rating | Select when I²C bus integration is preferred and bipolar signal handling is not required |
| MCP41010-I/P | SPITM interface, 10kΩ RTOTAL, 257 taps, 2.7V–5.5V supply, volatile memory only | Lacks nonvolatile storage-requires host MCU to reload wiper position at every power-up | Select when cost sensitivity outweighs need for autonomous power-on state recovery |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9313ZMI uniquely combines ±VCC analog rail support, true nonvolatile wiper retention, and ultra-low 1kΩ resistance-making it optimal for low-voltage, high-precision, self-initializing analog trimming where mechanical reliability and startup repeatability are critical.

FAQ
What is the maximum allowable voltage difference between RH/VH and RL/VL terminals for X9313ZMI?
The X9313ZMI specifies ΔV = |VH − VL| ≤ 4V for the Z-series (including X9313ZMI), as defined in Absolute Maximum Ratings. This limit applies regardless of VCC level and ensures safe operation of the internal resistor array and switching network. Exceeding 4V risks irreversible damage to the wiper switches or resistive elements.
Does X9313ZMI support true bipolar operation with negative supply rails?
Yes - X9313ZMI supports terminal voltages from –VCC to +VCC, meaning it can operate with VSS = 0V and RH/VH = –5V, RL/VL = +5V (if VCC = 5V), or with split supplies like VCC = +5V, VSS = –5V, enabling direct use in ±5V op-amp circuits without level-shifting circuitry.
How is wiper position stored in nonvolatile memory on X9313ZMI?
Wiper position is stored when CS transitions HIGH while INC is held HIGH. This store command takes 10ms (tWR) to complete. During this time, the device enters standby mode and ignores further INC edges. Once complete, the value remains retained for 100 years without power.
Can X9313ZMI be used as a two-terminal variable resistor, and what is its effective resistance range?
Yes - X9313ZMI can be configured as a two-terminal variable resistor by connecting either RH/VH or RL/VL to RW/VW. Its effective resistance ranges from near 0Ω (wiper at terminal) to 1kΩ (full array), with 31 discrete steps. Wiper resistance (40Ω typ.) adds directly to the minimum on-resistance.
What is the recommended power-up sequence for reliable X9313ZMI initialization?
Apply VCC and VSS first, then assert CS and INC HIGH before or concurrently with VCC reaching final value. This prevents spurious wiper movement or unintended store operations during ramp-up. Full electrical specifications apply only after VCC stabilizes and ≥1ms elapses.
