Product details
Overview
X9313ZMZ-3 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 operates from 3V to 5.5V supply and is housed in an 8-lead MSOP package. It serves as a solid-state replacement for mechanical potentiometers in precision analog trimming applications.
For engineers reviewing the X9313ZMZ-3 datasheet, X9313ZMZ-3 pinout, X9313ZMZ-3 application, or X9313ZMZ-3 equivalent, key selection considerations include its 1kΩ RTOTAL tolerance (±20%), wiper resistance (40Ω typ. at 5V), 100,000-cycle endurance, 100-year data retention, and compatibility with commercial temperature range (0°C to +70°C) designs requiring stable, reprogrammable resistance control.
Technical Context
The X9313ZMZ-3 implements a resistor ladder of 31 elements with a digitally controlled wiper switch network driven by a 5-bit up/down counter. Its control logic uses negative-edge-triggered INC input with U/D direction select and CS-gated store-on-high functionality, enabling deterministic wiper positioning and nonvolatile recall at power-up.
It supports true three-terminal potentiometer and two-terminal variable resistor configurations, with terminal voltages rated from –VCC to +VCC and absolute wiper current limited to ±4.4mA. The device features make-before-break switching and temperature-compensated resistance matching (±20% RTOTAL, ±300ppm/°C tempco).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 1kΩ ±20% - defines full-scale analog adjustment range and load interaction in voltage divider or current-limiting roles |
| Wiper resistance | 40Ω typical at VCC = 5V - contributes directly to signal path insertion loss and thermal noise floor |
| Supply voltage range | 3V to 5.5V - enables interoperability with both 3.3V and 5V digital control systems without level shifting |
| Operating temperature | 0°C to +70°C - suitable for commercial-grade embedded instrumentation and consumer electronics |
| Nonvolatile endurance | 100,000 data changes per bit - supports frequent calibration updates over product lifetime without wear-out risk |
| Power-up behavior | Recalls last stored wiper position - ensures repeatable startup state without host initialization overhead |
| Terminal voltage range | –VCC to +VCC - allows bipolar signal handling (e.g., ±5V op-amp circuits) without external clamping |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), dimensions per JEDEC MO-187-AA, body size 3.0mm × 3.0mm × 1.10mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply rail | Provides power for internal logic and resistor array; must be stabilized before CS/INC activation to prevent spurious wiper moves |
| VSS | Ground reference | Common return for all digital inputs and analog terminals; requires low-impedance connection to minimize noise coupling into RH/RL/RW |
| RH/VH | High terminal | Fixed end of resistor array; functions as voltage source node in divider mode or high-side connection in variable resistor mode |
| RL/VL | Low terminal | Fixed end of resistor array; functions as ground/reference node in divider mode or low-side connection in variable resistor mode |
| RW/VW | Wiper terminal | Movable contact point; output node whose voltage or resistance is programmatically adjustable; series resistance impacts signal fidelity |
| CS | Chip select | Active-low enable; initiates control sequence and gates nonvolatile store when transitioned high while INC = high |
| U/D | Direction control | Sets wiper increment/decrement direction during INC transitions; latched on CS assertion, not edge-sensitive |
| INC | Increment clock | Negative-edge-triggered; advances wiper one tap per valid edge; timing window (tIW = 5µs) defines minimum settling delay before VW stabilizes |
Key Features
| Feature | Design Value |
|---|---|
| 3-wire serial interface | Eliminates need for I²C or SPI peripherals; compatible with GPIO-driven microcontrollers using minimal firmware overhead |
| Nonvolatile wiper storage | Enables factory-trimmed calibration persistence across power cycles without external EEPROM or battery backup |
| ±VCC terminal voltage rating | Supports direct integration into bipolar analog signal paths (e.g., op-amp feedback networks) without external protection diodes |
| Make-before-break switching | Prevents open-circuit transients during wiper movement, critical for maintaining continuity in active filter or gain-control loops |
| Temperature-compensated resistor array | Ensures stable resistance ratio tracking across 0°C to +70°C, minimizing drift-induced errors in precision voltage references |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ-10 | I²C interface, 10kΩ RTOTAL, 256-tap resolution, ±15V terminal rating | Better suited for high-resolution, wide-voltage industrial sensors; lacks ±VCC symmetry of X9313ZMZ-3 | Select when I²C bus availability and higher resolution outweigh need for 3-wire simplicity and bipolar terminal compliance |
| MCP41010-I/P | SPITM interface, 10kΩ RTOTAL, volatile wiper register, no nonvolatile memory | Requires host MCU to reload wiper position at every power-up; lower cost but no persistent calibration | Select when system already uses SPI peripherals and calibration is managed externally; avoid if unattended operation or factory trim persistence is required |
Compared with AD5243BRMZ-10 and MCP41010-I/P, the X9313ZMZ-3 uniquely combines 3-wire simplicity, 1kΩ low-R value for current-sensing applications, ±VCC terminal compatibility, and guaranteed nonvolatile recall-making it optimal for cost-sensitive, self-contained analog trimming in commercial-grade equipment.

FAQ
What is the maximum allowable voltage across RH and RL terminals for X9313ZMZ-3?
The X9313ZMZ-3 specifies ΔV = |VH − VL| ≤ 4V under recommended operating conditions. This limit applies regardless of VCC level and ensures safe operation of the 1kΩ resistor array without exceeding power dissipation or causing irreversible resistance shift. Exceeding 4V may degrade endurance or cause parametric drift.
Does X9313ZMZ-3 require external pull-up or pull-down resistors on its control pins?
No, the X9313ZMZ-3 does not require external pull-up or pull-down resistors on CS, U/D, or INC inputs. Its input leakage current is ±10µA max, and VIH/VIL thresholds (2.0V/0.8V) are compatible with standard CMOS logic levels. However, floating inputs must be avoided-firmly tie U/D and INC to defined logic states during CS assertion to prevent unintended wiper movement.
Can X9313ZMZ-3 be used in a two-terminal variable resistor configuration?
Yes, the X9313ZMZ-3 supports two-terminal variable resistor operation by connecting either RH/VH or RL/VL to RW/VW and using the remaining terminal plus RW/VW as the adjustable element. In this mode, resistance varies from near-zero (wiper at shorted terminal) to RTOTAL (wiper at opposite end), with wiper resistance (40Ω typ.) contributing to minimum on-resistance.
How long does it take for X9313ZMZ-3 to stabilize its wiper voltage after an INC transition?
The X9313ZMZ-3 specifies tIW (INC to VW change) as 5µs maximum. This is the time from the falling edge of INC until the wiper voltage VW settles to its final value within ±1 MI (minimum increment). For reliable sampling, allow ≥10µs delay after each INC edge before reading VW in closed-loop control systems.
Is the X9313ZMZ-3 pin-compatible with other members of the X9313 family?
Yes, the X9313ZMZ-3 shares identical 8-lead MSOP pinout and electrical interface with all X9313 variants (e.g., X9313WMZ-3, X9313UMZ-3). Differences are limited to RTOTAL (1kΩ vs. 10kΩ/50kΩ), temperature grade (0°C to +70°C), and supply range (3V–5.5V); no PCB layout change is needed when substituting within the same package type.
