Product details
Overview
X9313USIZ 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, ±VCC terminal voltage range, and 10 kΩ end-to-end resistance. It operates as a three-terminal voltage divider or two-terminal variable resistor in analog signal conditioning circuits requiring stable, repeatable resistance trimming across power cycles.
For engineers reviewing the X9313USIZ datasheet, X9313USIZ pinout, X9313USIZ application, or X9313USIZ equivalent, this device supports industrial-grade (-40°C to +85°C) analog calibration, DC bias adjustment, and programmable gain control where EEPROM-retained settings, low standby current (500 µA max), and ±4.4 mA wiper current capability are critical selection criteria.
Technical Context
The X9313USIZ implements a 31-element resistor array with make-before-break wiper switching, driven by a 5-bit up/down counter decoded to select one of 32 tap points. Wiper position is stored in nonvolatile memory upon CS↑ while INC = HIGH, enabling automatic recall at power-up.
Its 3-wire interface uses asynchronous edge-triggered control: U/D sets direction, negative-edge-triggered INC steps the wiper, and CS enables operation and initiates store. Terminal voltages span -VCC to +VCC, supporting bipolar signal paths, and wiper resistance is 40 Ω (typ) at VCC = 5 V.
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 in precision trim applications. |
| Wiper tap count | 32 linear positions - provides 3.125% resolution per step (1/31 increment), enabling fine-grained analog parameter control. |
| Terminal voltage range | -VCC to +VCC - allows direct integration into bipolar op-amp feedback networks and rail-to-rail signal paths without level-shifting. |
| Nonvolatile memory endurance | 100,000 data changes per bit - supports field recalibration over product lifetime without wear-out concerns. |
| Supply voltage range | 4.5 V to 5.5 V - compatible with standard 5 V logic and analog rails; excludes 3 V operation (not supported by X9313USIZ). |
| Standby supply current | 500 µA max - minimizes quiescent power in battery-backed or always-on systems during idle periods. |
| Wiper resistance | 40 Ω (typ) at VCC = 5 V - contributes predictable series impedance in current-sensing or gain-setting configurations. |
Pinout & Package
Package: 8-lead SOIC (Pb-free), RoHS compliant, JEDEC MS-012-AA compliant outline (M8.15).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Provides power for internal logic and resistor array; must be applied before analog voltages to prevent latch-up. |
| VSS | Ground reference | Common return for digital control and analog terminals; requires low-impedance connection to minimize noise coupling. |
| CS | Chip Select input | Active-low enable: LOW selects device; HIGH with INC = HIGH stores wiper position to nonvolatile memory. |
| U/D | Up/Down direction control | Logic level determines wiper movement direction during INC transitions; may change dynamically while CS = LOW. |
| INC | Increment clock input | Negative-edge-triggered; each falling edge moves wiper one tap in direction set by U/D; timing min pulse width = 1 µs. |
| RH/VH | High terminal | Fixed end of resistor array; functions as VH in voltage divider mode; voltage range = -VCC to +VCC. |
| RL/VL | Low terminal | Fixed end of resistor array; functions as VL in voltage divider mode; voltage range = -VCC to +VCC. |
| RW/VW | Wiper terminal | Movable contact point; outputs intermediate voltage or resistance; series resistance ≈ 40 Ω at VCC = 5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, vibration sensitivity, and contact noise-enabling reliable operation in industrial environments. |
| Nonvolatile wiper position storage | Recalls last-set resistance value on power-up, ensuring consistent analog behavior without host MCU initialization overhead. |
| Temperature-compensated resistor array | ±300 ppm/°C end-to-end resistance drift ensures stable gain or bias settings across -40°C to +85°C operating range. |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions, avoiding glitches in op-amp feedback loops or sensor excitation paths. |
| 3-wire serial interface simplicity | Requires only three GPIOs (CS/U/D/INC) - no clock line or complex protocol stack needed for basic resistance programming. |
Applications
| Instrumentation Calibration | Programmable Gain Amplifier |
|---|---|
|
Use Scenario: Adjusting offset and span in 4–20 mA transmitter front-ends or precision ADC reference dividers. IC Role / Device Role / Timing Role: Three-terminal voltage divider setting DC bias or scaling factor; nonvolatile recall ensures factory calibration persists after power loss.

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 taps, 10 kΩ, 2.7–5.5 V supply; no nonvolatile storage (volatile only). | Requires external EEPROM or MCU state retention for power-cycle persistence; better suited for multi-channel synchronized adjustment. | Select when I²C bus integration and dual independent pots outweigh need for EEPROM retention. |
| MCP41010-I/P | SPI interface, single-channel, 256 taps, 10 kΩ, 2.7–5.5 V supply; includes nonvolatile memory with 1M endurance cycles. | Higher resolution (256 vs. 32) but slower SPI clock max (10 MHz); wiper voltage limited to 0–VDD (no ±VCC support). | Select when finer resolution and higher endurance are required, and bipolar signal handling is not needed. |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313USIZ offers unique ±VCC terminal compatibility and simpler 3-wire control, making it optimal for bipolar analog circuits where minimal GPIO count and guaranteed power-up repeatability are prioritized over tap count or serial bus standardization.

FAQ
What is the operating temperature range for the X9313USIZ?
The X9313USIZ is rated for industrial operation from -40°C to +85°C. This range is confirmed in the Ordering Information table on page 2 of FN8177 Rev 7.00, where "X9313USIZ*" is explicitly listed with "-40 to +85" under Temperature Range. It is not rated for commercial (0°C to +70°C) or extended ranges.
Does the X9313USIZ support 3 V operation?
No, the X9313USIZ does not support 3 V operation. Its specified VCC range is 4.5 V to 5.5 V, as stated in the Ordering Information table. The -3 suffix variants (e.g., X9313USIZ-3) support 3 V to 5.5 V, but the base X9313USIZ is strictly 5 V compatible.
How is wiper position stored and recalled in the X9313USIZ?
Wiper position is stored in nonvolatile memory when CS transitions HIGH while INC is held HIGH; it is automatically recalled on power-up. This behavior is defined in the Pin Descriptions (page 2) and Principles of Operation (page 3) of FN8177 Rev 7.00, with 100-year data retention and 100,000 write cycles guaranteed.
Can the X9313USIZ be used with bipolar analog signals?
Yes, the X9313USIZ supports bipolar operation: its RH/VH and RL/VL terminals accept voltages from -VCC to +VCC, and VW wiper output follows accordingly. This is explicitly specified in the Absolute Maximum Ratings (page 5) and Potentiometer Characteristics (page 5) sections of FN8177 Rev 7.00.
What package type is used for the X9313USIZ?
The X9313USIZ uses an 8-lead SOIC (Small Outline Integrated Circuit) package, Pb-free and RoHS compliant, with JEDEC MS-012-AA outline (drawing M8.15). This is confirmed in the Ordering Information table (page 2) and Package Outline Drawing (page 11) of FN8177 Rev 7.00.
