Product details
Overview
X9313ZMZT1 from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 1 kΩ end-to-end resistance, 3-wire serial interface (CS/U/D/INC), ±VCC terminal voltage range, and nonvolatile wiper position storage. It functions as a solid-state replacement for mechanical potentiometers in precision analog trimming applications such as DC bias adjustment in op-amp circuits.
For engineers reviewing the X9313ZMZT1 datasheet, X9313ZMZT1 pinout, X9313ZMZT1 application, or X9313ZMZT1 equivalent, key selection criteria include its 1 kΩ RTOTAL tolerance (±20%), 40 Ω typical wiper resistance at 5 V, 3–5.5 V supply compatibility, -40°C to +85°C industrial temperature range, and MSOP-8 package with make-before-break switching.
Technical Context
The X9313ZMZT1 implements a 31-element resistor array with a digitally controlled wiper driven by a 5-bit up/down counter and decoded via nonvolatile memory. Wiper movement is edge-triggered on INC with direction set by U/D, enabling precise incremental adjustment without host microcontroller intervention.
It operates in three functional modes: wiper positioning (CS low), nonvolatile store (CS rising edge with INC high), and standby (CS high, INC low). The device supports both three-terminal potentiometer and two-terminal variable resistor configurations, with terminal voltages rated from –VCC to +VCC and absolute linearity of ±1 MI (minimum increment).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 1 kΩ ±20% - defines full-scale resistance for voltage divider or current-limiting use; impacts resolution (32.3 Ω per step) |
| Wiper Resistance | 40 Ω typical at VCC = 5 V - contributes directly to output impedance error in bufferless voltage divider designs |
| Supply Voltage | 3 V to 5.5 V - enables direct interfacing with 3.3 V and 5 V logic systems without level shifting |
| Operating Temperature | -40°C to +85°C - qualified for industrial environments including motor control and sensor signal conditioning |
| Nonvolatile Endurance | 100,000 data changes per bit - supports long-term field calibration cycles without wear-out concerns |
| Power-Up Behavior | Recalls last stored wiper position - ensures repeatable startup state without host initialization overhead |
| Terminal Voltage Range | -VCC to +VCC - allows bipolar signal handling (e.g., ±5 V inputs) without external clamping diodes |
Pinout & Package
Package: 8-lead MSOP (Mo-187-AA compliant), 3.0 mm × 3.0 mm body, 0.65 mm pitch, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 3–5.5 V; powers internal CMOS logic and resistor array; must be stabilized before CS activation |
| VSS | Ground reference | Common return for all digital and analog paths; requires low-impedance connection to minimize noise coupling |
| 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 end opposite RH/VH; forms complete resistive path with RH/VH; supports bidirectional voltage swing |
| RW/VW | Wiper output | Switched tap point; series resistance ~40 Ω affects loading in high-precision dividers; make-before-break prevents open-circuit transients |
| CS | Chip select | Active-low enable; rising edge with INC high triggers nonvolatile store; must be held stable during INC transitions |
| U/D | Direction control | Static logic level sets wiper increment/decrement direction; can be changed dynamically while CS is low |
| INC | Increment clock | Negative-edge triggered; each pulse moves wiper one position; timing min. tIL = 1 µs, tIH = 1 µs, tCYC = 2 µs |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, vibration sensitivity, and contact bounce-enables >100k adjustment cycles in automated test equipment |
| Nonvolatile wiper storage | Retains last position across power cycles for deterministic startup in embedded sensor modules and power supplies |
| Make-before-break switching | Prevents momentary open-circuit at wiper during tap transitions-critical for maintaining loop stability in feedback networks |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift and ±20 ppm/°C ratiometric coefficient ensure stable divider ratio over industrial temperature range |
| Bipolar terminal voltage support | Allows direct use with ±5 V op-amps and AC-coupled signals without external level-shifting circuitry |

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, 10 kΩ RTOTAL, 256 taps, no nonvolatile store in basic version | Requires I²C master; higher resolution but lacks automatic power-up recall without external EEPROM | Preferred when multi-channel coordination or finer resolution is needed, and host can manage I²C protocol |
| MCP41010-I/P | SPI interface, 10 kΩ RTOTAL, volatile wiper only, 256 taps, 5 V supply only | No nonvolatile memory; requires host re-initialization after every power cycle | Selected for cost-sensitive 5 V-only systems where firmware handles startup calibration |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313ZMZT1 offers unique value in single-channel, 3-wire, nonvolatile operation at 1 kΩ-ideal for space-constrained industrial analog trimming where deterministic power-up behavior and minimal host overhead are critical.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313ZMZT1?
The X9313ZMZT1 specifies ΔV = |VH − VL| ≤ 4 V for the X9313Z variant. This limit is defined in the Absolute Maximum Ratings table and applies regardless of supply voltage. Exceeding 4 V risks irreversible damage to the internal resistor array switches and must be enforced in circuit design-e.g., via external clamping or voltage scaling.
Does X9313ZMZT1 support true bipolar operation with negative supply rails?
Yes, X9313ZMZT1 supports terminal voltages from –VCC to +VCC, meaning it operates correctly with VCC = 5 V and VH = +5 V, VL = –5 V (ΔV = 10 V), provided the absolute voltage on each terminal stays within –6 V to +7 V relative to VSS. However, the X9313Z variant's ΔV rating remains 4 V, so bipolar use requires limiting the differential voltage-not just referencing to VSS.
How does the nonvolatile store function work on X9313ZMZT1?
The X9313ZMZT1 stores the current wiper position in nonvolatile memory when CS transitions HIGH while INC is held HIGH. This store cycle takes 10 ms (tWR). After store completion, the device enters standby mode. Upon next power-up, the stored value is automatically loaded into the wiper counter, ensuring repeatable startup behavior without host intervention.
Can X9313ZMZT1 be used in a two-terminal variable resistor configuration?
Yes, X9313ZMZT1 can be configured as a two-terminal variable resistor by connecting either RH/VH or RL/VL to RW/VW and using the remaining fixed terminal plus RW/VW as the two endpoints. This configuration maintains the same 1 kΩ RTOTAL range and nonvolatile storage capability, commonly used in current-limiting or gain-setting applications where only resistance variation-not voltage division-is required.
What is the wiper resistance specification for X9313ZMZT1 and how does it affect circuit accuracy?
X9313ZMZT1 has a typical wiper resistance of 40 Ω at VCC = 5 V (max 100 Ω). In voltage divider applications, this series resistance introduces gain error proportional to RW / RTOTAL (e.g., ~4% error at 1 kΩ). For high-accuracy designs, this must be compensated in layout (e.g., buffering VW with an op-amp) or accounted for in calibration algorithms.
