Product details
Overview
X9313USZ-3 from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 32-tap linear resistor array with nonvolatile wiper position storage, 3-wire serial interface (CS/U/D/INC), ±VCC terminal voltage tolerance, and 10 kΩ end-to-end resistance - used for precision analog trimming in voltage divider and variable resistor configurations within industrial control and signal conditioning circuits.
For engineers reviewing the X9313USZ-3 datasheet, X9313USZ-3 pinout, X9313USZ-3 application, or X9313USZ-3 equivalent, this page delivers verified electrical specs, SOIC-8 package mapping, real-world use cases, and validated alternative parts - all grounded in FN8177 Rev 7.00 and official Intersil ordering data.
Technical Context
The X9313USZ-3 integrates a 31-element resistor ladder, 5-bit up/down counter, nonvolatile memory for power-up recall, and make-before-break wiper switching. Its control logic responds to CS-active low selection, edge-triggered INC, and level-sensitive U/D to increment/decrement wiper position.
It operates across 3V to 5.5V supply, supports terminal voltages from –VCC to +VCC, and maintains wiper position with 100-year data retention after 100,000 write cycles - enabling reliable recalibration-free operation in embedded analog subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance (RTOTAL) | 10 kΩ ±20% - defines full-scale analog range for voltage division or current limiting. |
| Wiper resolution | 32 discrete taps (31 resistive elements) - provides ~3% step resolution for fine analog adjustment. |
| Supply voltage range | 3V to 5.5V - compatible with both 3.3V and 5V logic systems without level shifting. |
| Terminal voltage range | –VCC to +VCC - enables bipolar signal handling (e.g., ±5V rails) without external clamping. |
| Wiper resistance | 40 Ω typical at VCC = 5V - minimizes insertion error in precision voltage divider applications. |
| Nonvolatile store time | 10 ms - ensures reliable wiper position retention during power cycling without external EEPROM. |
| Active supply current | 3 mA max - supports low-power operation in battery-backed or energy-constrained systems. |
| Standby current | 500 µA max - allows extended sleep mode between trim updates. |
Pinout & Package
Package: 8-lead SOIC (Pb-free), RoHS-compliant, JEDEC MS-012-AA compliant (M8.15 outline).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply rail | Power source for internal logic and resistor array; must be stable before CS/INC transitions. |
| VSS | Ground reference | Common return path for supply and signal terminals; required for proper wiper voltage referencing. |
| RH/VH | High terminal | Fixed end of resistor array; functions as top rail in voltage divider or one end of variable resistor. |
| RL/VL | Low terminal | Fixed end of resistor array; functions as bottom rail in voltage divider or other end of variable resistor. |
| RW/VW | Wiper output | Movable tap point; delivers interpolated voltage/current based on stored 5-bit counter value. |
| CS | Chip select | Active-low enable; initiates wiper movement when low, triggers nonvolatile store when rising edge occurs with INC high. |
| U/D | Direction control | Level-sensitive input determining wiper increment (+) or decrement (–) on each INC edge. |
| INC | Increment clock | Negative-edge-triggered control; advances wiper position only when CS is low and U/D is asserted. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, contact bounce, and environmental drift - ideal for sealed or high-vibration systems. |
| Nonvolatile wiper position storage | Recalls last-trimmed setting at power-up without host MCU intervention - reduces boot-time calibration overhead. |
| 3-wire serial interface | Requires only three GPIOs (CS/U/D/INC) - simplifies integration into resource-constrained microcontrollers. |
| Temperature-compensated resistor array | ±300 ppm/°C RTOTAL drift - maintains consistent gain/offset over 0°C to +70°C commercial temperature range. |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions - avoids signal dropout in active filter or amplifier bias networks. |
| Pb-free SOIC-8 packaging | RoHS-compliant M8.15 footprint - supports automated assembly and reflow soldering per J-STD-020. |

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, 256-tap resolution, 10 kΩ RTOTAL, ±15% tolerance. | Requires I²C master; higher resolution but no ±VCC terminal rating - limited to unipolar signal paths. | Choose for multi-channel trimming where I²C bus is available and bipolar voltage handling is not required. |
| MCP41010-I/P | SPI interface, single-channel, 257-tap resolution, 10 kΩ RTOTAL, ±20% tolerance, 5V-only supply. | No nonvolatile storage - wiper resets to mid-scale on power-up; requires host MCU to reload setting. | Choose for cost-sensitive designs where host firmware manages calibration persistence and 3-wire simplicity is less critical than SPI compatibility. |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313USZ-3 uniquely combines ±VCC terminal voltage support, true nonvolatile recall without host dependency, and minimal 3-wire GPIO footprint - making it optimal for robust, self-contained analog trimming in industrial and telecom equipment.

FAQ
What is the operating temperature range for the X9313USZ-3?
The X9313USZ-3 is rated for 0°C to +70°C (commercial grade), as confirmed in the Ordering Information table on page 2 of FN8177 Rev 7.00. This distinguishes it from industrial-grade variants like X9313USIZ-3 (–40°C to +85°C) and confirms its suitability for indoor, non-extreme ambient applications.
Does the X9313USZ-3 require an external clock or microcontroller to retain wiper position?
No. The X9313USZ-3 stores wiper position in on-chip nonvolatile memory and automatically recalls it at power-up without external components. A store operation is triggered by a rising edge on CS while INC is high, and data retention is guaranteed for 100 years per the Endurance and Data Retention table on page 6.
Can the X9313USZ-3 be used with bipolar supply rails such as ±5V?
Yes. The X9313USZ-3 supports terminal voltages from –VCC to +VCC, and with VCC = 5V, RH/VH and RL/VL can swing from –5V to +5V. This is explicitly stated in the Absolute Maximum Ratings and Potentiometer Characteristics tables (pages 5–6), enabling direct use in dual-supply op-amp circuits.
What is the maximum wiper current rating for the X9313USZ-3?
The X9313USZ-3 has a maximum wiper current rating of ±4.4 mA, as specified in the Recommended Operating Conditions table (page 5). Exceeding this may cause irreversible damage to the wiper switch network, especially under high-voltage differentials across RTOTAL.
Is the X9313USZ-3 pin-compatible with other members of the X9313 family?
Yes - all X9313 variants, including X9313USZ-3, share identical 8-pin SOIC (M8.15) pinouts and functional pin assignments (VCC, VSS, RH/VH, RL/VL, RW/VW, CS, U/D, INC), as shown in the Pin Descriptions and Pinouts sections (pages 2 and 3). Only RTOTAL value, supply range, and temperature grade differ across part numbers.
