Product details
Overview
X9313ZSZ-3T1 from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 3-wire serial interface (CS/U/D/INC), nonvolatile wiper position storage, and 1kΩ end-to-end resistance. It operates from 3V to 5.5V, supports ±VCC terminal voltages, and functions as a three-terminal voltage divider or two-terminal variable resistor in precision analog trimming applications.
For engineers reviewing the X9313ZSZ-3T1 datasheet, X9313ZSZ-3T1 pinout, X9313ZSZ-3T1 application, or X9313ZSZ-3T1 equivalent, key selection criteria include its 1kΩ RTOTAL tolerance (±20%), 40Ω typical wiper resistance at 5V, 100,000-cycle endurance, 100-year data retention, and SOIC-8 packaging for board space-constrained analog control circuits.
Technical Context
The X9313ZSZ-3T1 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, ensuring power-up recall. Terminal voltage range spans –VCC to +VCC, supporting bipolar signal conditioning, and absolute linearity is ±1 MI (minimum increment = RTOTAL/31) with ratiometric temperature coefficient of ±20 ppm/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 1kΩ ±20% - defines full-scale resistance range for gain/offset calibration accuracy |
| Wiper Resistance | 40Ω typical at VCC = 5V - contributes minimal series error in low-impedance feedback paths |
| Voltage Range (RH/VH, RL/VL) | –VCC to +VCC - enables use in bipolar op-amp configurations without level-shifting |
| Endurance | 100,000 data changes per bit - supports long-term field recalibration in maintenance-critical systems |
| Data Retention | 100 years - ensures factory-trimmed settings persist over product lifetime without backup power |
| Supply Voltage | 3V to 5.5V - compatible with both 3.3V and 5V logic domains without level translation |
| Active Current | 3mA max - low dynamic power suitable for battery-backed or energy-sensitive analog subsystems |
Pinout & Package
Package: 8-lead SOIC (Pb-free, RoHS compliant, M8.15 outline), 3.9mm × 4.9mm footprint, 1.27mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 3V–5.5V; powers internal CMOS logic and resistor array biasing |
| VSS | Ground reference | Return path for supply and signal currents; must be low-impedance for noise immunity |
| RH/VH | High terminal | Fixed end of resistor array; voltage polarity relative to wiper depends on U/D state |
| RL/VL | Low terminal | Fixed end of resistor array; forms complete resistive path with RH/VH and RW/VW |
| RW/VW | Wiper output | Movable tap point; delivers intermediate voltage/current; 40Ω typical series resistance |
| CS | Chip select | Active-low enable; rising edge with INC = HIGH triggers nonvolatile store operation |
| U/D | Direction control | Logic level sets wiper increment/decrement direction during INC toggling |
| INC | Increment clock | Negative-edge triggered; advances wiper one position per valid transition |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, contact bounce, and vibration sensitivity in industrial environments |
| Nonvolatile wiper storage | Recalls last-set position at power-up without external EEPROM or initialization firmware |
| Make-before-break switching | Prevents open-circuit glitches during wiper movement-critical in closed-loop feedback paths |
| Temperature-compensated array | ±20 ppm/°C ratiometric TC ensures stable voltage division across –40°C to +85°C |
| 3-wire serial interface | Minimal GPIO usage (3 pins) vs. SPI/I²C; simplifies microcontroller integration in resource-limited designs |

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, 10kΩ RTOTAL, 256 taps, no nonvolatile memory | Requires external EEPROM or MCU firmware for power-up recall; higher resolution but larger package | Select when multi-channel adjustment or finer resolution outweighs need for autonomous power-up behavior |
| MCP41010-I/P | SPI interface, 10kΩ RTOTAL, volatile wiper register, 128 taps, 5V-only supply | No inherent power-up recall; demands host MCU initialization at boot; lower cost but adds software overhead | Select for cost-sensitive, MCU-managed systems where initialization sequence is already established |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313ZSZ-3T1 uniquely combines nonvolatile storage, 3-wire simplicity, 1kΩ low-value resistance, and bipolar terminal capability-making it optimal for self-contained analog trimming where reliability and zero-firmware operation are mandatory.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313ZSZ-3T1?
The X9313ZSZ-3T1 specifies ΔV = |VH − VL| ≤ 4V for the X9313Z variant. This limit ensures safe operation of the internal resistor array and switching elements. Exceeding 4V may cause irreversible damage or parametric shift. The device supports terminal voltages from –VCC to +VCC, but the differential voltage must remain within this 4V ceiling regardless of supply rail.
Does X9313ZSZ-3T1 require an external clock or microcontroller to retain wiper position after power loss?
No, X9313ZSZ-3T1 does not require external components for wiper position retention. Its integrated nonvolatile memory stores the last wiper setting automatically when CS rises while INC is high. Upon power-up, the stored value is recalled without MCU intervention, making X9313ZSZ-3T1 fully autonomous for preset restoration.
Can X9313ZSZ-3T1 be used in a bipolar signal path with ±5V supplies?
Yes, X9313ZSZ-3T1 supports terminal voltages from –VCC to +VCC. With VCC = 5V, RH/VH and RL/VL can swing from –5V to +5V, enabling direct use in bipolar op-amp stages, AC-coupled filters, and symmetric signal conditioning circuits without level-shifting circuitry.
What is the wiper resistance specification for X9313ZSZ-3T1 and how does it affect circuit performance?
X9313ZSZ-3T1 has a typical wiper resistance of 40Ω at VCC = 5V (max 100Ω). This low on-resistance minimizes gain error in feedback networks and voltage drop in current-setting paths. For example, in a 1MΩ PGA feedback loop, it introduces <0.004% error-critical for high-accuracy medical and test equipment where X9313ZSZ-3T1 is commonly deployed.
Is X9313ZSZ-3T1 RoHS compliant and what is its moisture sensitivity level (MSL)?
Yes, X9313ZSZ-3T1 is RoHS compliant with 100% matte tin (e3) termination finish, compatible with both SnPb and Pb-free soldering. As an SOIC-8 package, it conforms to JEDEC MS-012-AA and carries MSL-1 rating-unlimited floor life at ≤30°C/60% RH, requiring no baking prior to reflow.
