Product details
Overview
X9313ZS-3 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 terminal voltages from –VCC to +VCC, and delivers ±4.4mA wiper current for analog signal trimming in precision voltage dividers and bias control circuits.
For engineers reviewing the X9313ZS-3 datasheet, X9313ZS-3 pinout, X9313ZS-3 application, or X9313ZS-3 equivalent, this device serves as a solid-state replacement for mechanical potentiometers in systems requiring repeatable, power-up stable resistance settings-especially where temperature-compensated linearity, low standby current (500µA max), and RoHS-compliant SOIC packaging are critical.
Technical Context
The X9313ZS-3 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 nonvolatile memory storing the last position for automatic recall at power-up.
Control logic responds to negative-edge-triggered INC input while U/D sets direction; CS enables operation and initiates store-on-high when INC is high. The device supports both three-terminal potentiometer and two-terminal variable resistor configurations, with wiper resistance typically 40Ω at VCC = 5V and absolute linearity ±1 MI (minimum increment).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance (RTOTAL) | 1kΩ ±20% - defines full-scale adjustment range and power dissipation limit (16mW max) |
| Supply voltage range | 3V to 5.5V - enables direct compatibility with 3.3V and 5V logic/system rails |
| Wiper current rating | ±4.4mA - determines maximum allowable load current without exceeding voltage drop or heating limits |
| Active supply current | 3mA max - sets dynamic power budget during wiper adjustment sequences |
| Standby supply current | 500µA max - enables low-power retention mode between adjustments |
| Nonvolatile memory endurance | 100,000 data changes per bit - ensures long-term reliability in field-programmable calibration loops |
| Temperature coefficient | ±300 ppm/°C (RTOTAL), ±20 ppm/°C (ratiometric) - maintains resistance stability across industrial temperature range (–40°C to +85°C) |
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 | Positive supply rail | Provides power for internal logic, memory, and resistor array; must be applied before control signals per power-up sequence |
| VSS | Ground reference | Common return path for all digital and analog functions; required for proper wiper voltage referencing |
| CS | Chip select input | Active-low enable; stores wiper position in NV memory when transitioned high while INC = high |
| U/D | Direction control input | Sets wiper movement direction (up/down) during INC transitions; may change dynamically while CS = low |
| INC | Increment control input | Negative-edge-triggered; advances wiper one tap per edge, direction determined by U/D state |
| RH/VH | High terminal | Fixed end of resistor array; voltage potential relative to RL/VL defines full-scale output range |
| RL/VL | Low terminal | Fixed end of resistor array; referenced to VSS or negative supply; forms voltage divider with RH/VH |
| RW/VW | Wiper terminal | Movable tap point; outputs intermediate voltage/current; series resistance ~40Ω at 5V affects loading in precision applications |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Recalls last setting at power-up without external controller intervention-enables factory-trimmed calibration persistence |
| 3-wire serial interface | Uses only CS, U/D, and INC pins-minimizes GPIO count and eliminates need for clock or data lines in microcontroller-constrained designs |
| Temperature-compensated resistor array | ±300 ppm/°C RTOTAL drift and ±20 ppm/°C ratiometric tracking-maintains voltage division accuracy across –40°C to +85°C |
| Make-before-break wiper switching | Prevents open-circuit glitches during tap transitions-critical for stable biasing in op-amp feedback networks and regulator adjustment |
| Low-power standby mode | 500µA max current when deselected-reduces system quiescent power in battery-operated or energy-sensitive applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5170BRMZ-10 | 10kΩ RTOTAL, I²C interface, 64 taps, 2.7–5.5V supply | Requires I²C bus resources; higher resolution but larger end-to-end resistance | Choose when I²C infrastructure exists and finer 64-step granularity is needed for high-precision trimming |
| MCP41010-I/P | 10kΩ RTOTAL, SPI interface, 257 taps, 2.7–5.5V supply, volatile wiper register | No nonvolatile storage-requires external MCU to reload setting on power-up | Choose when SPI is preferred and system already manages wiper state externally; lower cost for non-persistent use cases |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9313ZS-3 offers unique value in 1kΩ low-resistance operation, 3-wire minimal interface, and guaranteed power-up repeatability without host intervention-making it optimal for space-constrained, self-contained analog calibration tasks.

FAQ
What is the operating temperature range for the X9313ZS-3?
The X9313ZS-3 is rated for industrial temperature operation from –40°C to +85°C. This range is confirmed in the Ordering Information table (Page 2) and Recommended Operating Conditions (Page 5) of the FN8177 datasheet. The device maintains its specified end-to-end resistance tolerance (±20%), linearity (±1 MI), and nonvolatile memory functionality across this full range.
Does the X9313ZS-3 require an external clock or data line for communication?
No, the X9313ZS-3 uses a 3-wire asynchronous interface with only CS, U/D, and INC inputs-no clock or serial data line is required. As stated in the datasheet "Features" section (Page 1) and "Principles of Operation" (Page 3), wiper position is advanced on each negative edge of INC, with direction controlled by the logic level on U/D while CS is low.
How is wiper position stored and recalled in the X9313ZS-3?
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 explicitly defined in the "Chip Select (CS)" section (Page 3) and "Instructions and Programming" (Page 3). The datasheet confirms 100-year data retention and 100,000 write cycles for this function.
Can the X9313ZS-3 be used with negative supply voltages on its terminals?
Yes-the X9313ZS-3 supports terminal voltages from –VCC to +VCC, meaning VH and VL can swing symmetrically around VSS. Page 1 states "Terminal voltages ±VCC", and Page 5 Absolute Maximum Ratings specify voltage on VH/VL/VW with respect to VSS as –6V to +7V. This enables bipolar signal handling in op-amp circuits powered from split supplies.
What package type and footprint does the X9313ZS-3 use?
The X9313ZS-3 uses an 8-lead SOIC package (Pb-free, RoHS compliant) with JEDEC MS-012-AA outline (M8.15 drawing). Dimensions are 3.9mm × 4.9mm body size and 1.27mm lead pitch. This is confirmed in the Ordering Information table (Page 2) and Package Outline Drawing (Page 11) of the FN8177 datasheet.
