Product details
Overview
X9313ZS from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 1kΩ end-to-end resistance, 3-wire serial interface (CS/U/D/INC), nonvolatile wiper position storage, and ±VCC terminal voltage capability. It functions as a solid-state replacement for mechanical potentiometers in precision analog trimming applications requiring power-up recall and low-power operation.
For engineers reviewing the X9313ZS datasheet, X9313ZS pinout, X9313ZS application, or X9313ZS equivalent, key selection criteria include its 1kΩ RTOTAL tolerance (±20%), 3V–5.5V supply range, 0°C to +70°C commercial temperature grade, SOIC-8 package, and compatibility with voltage divider or two-terminal variable resistor configurations.
Technical Context
The X9313ZS 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 wiper resistance typically 40Ω at VCC = 5V.
Nonvolatile memory stores the last wiper position on CS↑ while INC = HIGH, ensuring automatic recall at power-up. The device operates in active mode (≤3mA) or standby mode (≤500µA), with all control inputs (CS, U/D, INC) compatible with standard CMOS logic levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 1kΩ ±20% - defines full-scale resistance range for voltage divider or current-limiting use |
| Wiper taps | 32 linear positions - enables 3.125% resolution per step across full resistance range |
| VCC range | 3V to 5.5V - supports dual-supply systems and legacy 5V or modern 3.3V logic interfaces |
| Terminal voltage | −VCC to +VCC - allows bipolar signal handling without external level-shifting circuitry |
| Active current | ≤3mA max - enables integration into low-power embedded systems without thermal derating |
| Standby current | ≤500µA max - preserves battery life in always-on analog front-end applications |
| Endurance | 100,000 data changes per bit - ensures long-term reliability in field-adjustable calibration systems |
| Data retention | 100 years - guarantees wiper setting persistence across product lifecycle without refresh |
Pinout & Package
Package: 8-lead SOIC (Pb-free, RoHS compliant), M8.15 outline, 3.9mm × 4.9mm body, 1.27mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply voltage input | Power rail for internal logic and resistor array; must be applied before signal voltages per power-up sequence |
| VSS | Ground reference | Common return path for all digital and analog functions; decoupling capacitor required near pin |
| CS | Chip select input | Active-low enable; initiates wiper movement when LOW and triggers nonvolatile store on rising edge with INC = HIGH |
| U/D | Direction control input | Logic level determines wiper increment (HIGH) or decrement (LOW); may be changed dynamically during CS = LOW |
| INC | Increment clock input | Negative-edge triggered; each falling edge moves wiper one position in direction set by U/D |
| 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 of resistor array; forms complete resistive path with RH/VH and RW/VW |
| RW/VW | Wiper terminal | Movable contact point; series resistance ≤100Ω ensures minimal loading in high-impedance feedback paths |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, vibration sensitivity, and contact noise inherent in analog potentiometers |
| 3-wire serial interface | Requires only three GPIOs (CS/U/D/INC) - no SPI/I²C peripheral needed, reducing MCU resource usage |
| Nonvolatile wiper storage | Recalls last setting at power-up without host intervention - essential for factory-trimmed calibration |
| Temperature-compensated array | ±300 ppm/°C end-to-end TC and ±20 ppm/°C ratiometric TC ensure stable gain/offset over temperature |
| Make-before-break switching | Prevents open-circuit glitches during wiper transitions - critical for uninterrupted bias or feedback paths |
| Pb-free SOIC packaging | RoHS-compliant M8.15 footprint enables drop-in replacement in existing 8-lead SOIC layouts |

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, 10kΩ RTOTAL, 64-tap resolution, 2.7V–5.5V supply | Requires I²C bus resources; higher RTOTAL limits current-handling capability in low-impedance circuits | Select when system already uses I²C and higher resolution is needed; verify 10kΩ compatibility with existing feedback networks |
| MCP41010-I/P | SPI interface, 10kΩ RTOTAL, 257-tap resolution, 2.7V–5.5V supply | Needs dedicated SPI peripheral and chip-select line; larger package (PDIP-8 vs SOIC-8) | Choose for applications requiring finer adjustment granularity and SPI-native microcontrollers; confirm board space for through-hole mounting |
Compared with AD5171BRMZ-10 and MCP41010-I/P, the X9313ZS offers simpler 3-wire control with lower pin count, tighter 1kΩ resistance matching for low-impedance analog paths, and guaranteed SOIC-8 footprint compatibility - making it optimal for cost-sensitive, space-constrained trimming where moderate resolution suffices.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313ZS?
The X9313ZS supports a maximum differential voltage ΔV = |VH − VL| of 4V under recommended operating conditions. This limit applies regardless of VCC level and is specified in the Absolute Maximum Ratings table. Exceeding 4V risks irreversible damage to the internal resistor array or wiper switches. For designs requiring higher voltage handling, consider the X9313W or X9313U variants rated for 10V.
Does X9313ZS require an external pull-up resistor on the INC pin?
No, the X9313ZS does not require an external pull-up resistor on the INC pin. Its INC input has CMOS-compatible thresholds (VIL ≤ 0.8V, VIH ≥ 2V) and exhibits ≤10µA leakage current, allowing direct connection to microcontroller GPIOs configured as open-drain or push-pull outputs. Internal design ensures reliable negative-edge detection without external biasing components.
Can X9313ZS be used in a bipolar signal path with ±5V supplies?
Yes, X9313ZS supports terminal voltages from −VCC to +VCC, and its VCC range includes 5V operation. When powered from +5V (VCC = 5V, VSS = 0V), RH/VH and RL/VL can swing from −5V to +5V relative to VSS, enabling true bipolar signal handling in configurations like AC-coupled gain control or offset adjustment. Ensure wiper current stays within ±4.4mA limits.
How many times can the wiper position of X9313ZS be stored to nonvolatile memory?
The X9313ZS guarantees a minimum endurance of 100,000 data changes per bit in its nonvolatile memory. Each store operation (CS↑ with INC = HIGH) counts as one write cycle. This endurance rating ensures reliable recalibration over the product's operational lifetime, even in applications requiring frequent field adjustments such as test equipment or adaptive sensor conditioning circuits.
Is the X9313ZS pinout compatible with other members of the X9313 family in SOIC-8 packages?
Yes, all X9313 variants in 8-lead SOIC packages-including X9313ZS, X9313WSZ, and X9313USZ-share identical pinouts per the M8.15 outline. Pin 1 (VCC) through Pin 8 (VSS) are functionally and physically aligned, enabling direct PCB-level substitution among temperature grades (commercial vs. industrial) and resistance values (1kΩ, 10kΩ, 50kΩ) without layout modification.
