Product details
Overview
X9313ZMIZ from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 1kΩ end-to-end resistance, ±VCC terminal voltage capability, nonvolatile wiper position storage, and 3-wire serial interface - used for precision analog trimming in industrial sensor signal conditioning circuits.
For engineers reviewing the X9313ZMIZ datasheet, X9313ZMIZ pinout, X9313ZMIZ application, or X9313ZMIZ equivalent, key selection criteria include its -40°C to +85°C industrial temperature range, MSOP-8 package, 3V–5.5V supply compatibility, ±4.4mA max wiper current, and guaranteed 100-year data retention in nonvolatile memory.
Technical Context
The X9313ZMIZ 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 direction controlled by U/D and edge-triggered stepping via INC.
Wiper position is stored in nonvolatile memory on CS↑ while INC = HIGH, ensuring power-up recall to last-saved setting. Terminal voltages support rail-to-rail operation from -VCC to +VCC, and wiper resistance is specified at 40Ω (typ) at VCC = 5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 1kΩ ±20% - sets full-scale resistance for gain/offset calibration networks |
| Operating Voltage | 3V to 5.5V - supports dual-supply and single-supply systems without level-shifting |
| Temperature Range | -40°C to +85°C - qualified for industrial-grade embedded control and instrumentation |
| Wiper Current Limit | ±4.4mA - defines maximum allowable current through RH–RW or RW–RL path |
| Nonvolatile Retention | 100 years - ensures factory-trimmed settings persist over product lifetime |
| Endurance | 100,000 write cycles - supports repeated field recalibration without wear-out risk |
| Wiper Resistance | 40Ω (typ) at VCC = 5V - contributes minimal series error in low-impedance feedback paths |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), dimensions per JEDEC MO-187-AA (pkg drawing M8.118), 3.0mm × 3.0mm footprint, 0.65mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RH/VH | High-side fixed terminal | Equivalent to mechanical potentiometer's "top" terminal; voltage polarity relative to wiper depends on U/D state |
| RL/VL | Low-side fixed terminal | Equivalent to mechanical potentiometer's "bottom" terminal; referenced to VSS but supports negative bias down to -VCC |
| RW/VW | Wiper output terminal | Switched connection to one of 32 taps; 40Ω typical series resistance affects precision in high-gain feedback loops |
| VCC | Positive supply input | 3V–5.5V logic and analog supply; powers internal CMOS control and memory circuitry |
| VSS | Ground reference | Return path for all digital and analog currents; must be low-impedance for noise immunity |
| CS | Chip select input | Active-low enable; rising edge with INC = HIGH triggers nonvolatile store operation |
| U/D | Direction control input | Sets wiper increment/decrement direction; stable during CS = LOW for multi-step adjustment |
| INC | Increment clock input | Negative-edge triggered; each pulse moves wiper one position; timing min pulse width = 1µs |
Key Features
| Feature | Design Value |
|---|---|
| 3-wire serial interface | Eliminates need for I²C/SPI peripherals; uses only CS, U/D, and edge-triggered INC for microcontroller GPIO control |
| Nonvolatile wiper storage | Guarantees repeatable startup behavior without host MCU initialization overhead or external EEPROM |
| Rail-to-rail terminal voltage | Supports ±VCC operation (e.g., VH = +5V, VL = -5V), enabling bipolar signal conditioning in op-amp circuits |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift enables stable gain/offset over industrial temperature range without recalibration |
| Make-before-break switching | Prevents open-circuit glitches during wiper movement, critical for closed-loop stability in active filter or regulator 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 | I²C interface, 256-tap resolution, 10kΩ RTOTAL, 2.7–5.5V supply | Requires I²C master; higher resolution but larger package (10-lead MSOP); no ±VCC terminal rating | Choose when higher resolution and standard bus integration outweigh ±VCC operation and simpler 3-wire control. |
| MCP41HV51-103 | 3-wire SPI interface, 256-tap, 10kΩ RTOTAL, ±12V terminal rating, 4.5–16V supply | Wider voltage range but requires SPI clock/data lines; no nonvolatile store on power-up - needs external command | Choose when bipolar ±12V signal paths dominate and SPI infrastructure already exists; avoid if true power-on default is required. |
Compared with AD5170BRMZ-10 and MCP41HV51-103, the X9313ZMIZ delivers deterministic power-up behavior without host intervention, supports true rail-to-rail analog terminals at lower system pin count, and offers optimal trade-off between resolution, endurance, and industrial temperature reliability for cost-sensitive embedded trimming.

FAQ
What is the maximum allowable voltage across RH and RL terminals for X9313ZMIZ?
The X9313ZMIZ specifies ΔV = |VH − VL| ≤ 4V for the Z-series (1kΩ variant). This limit ensures safe operation of the internal resistor array and wiper switches. Exceeding 4V risks irreversible damage to the thin-film elements, even if individual terminal voltages remain within -VCC to +VCC bounds. Always verify voltage differential in your circuit before final layout.
Does X9313ZMIZ retain its wiper position after power cycling?
Yes, X9313ZMIZ stores the wiper position in nonvolatile memory upon a valid store command (CS↑ while INC = HIGH), and automatically recalls that value at power-up. The datasheet guarantees 100 years of data retention under normal operating conditions, making it suitable for applications requiring factory-set calibration persistence without battery backup or external memory.
Can X9313ZMIZ operate with a 3.3V supply?
Yes, X9313ZMIZ supports VCC from 3V to 5.5V, fully compatible with 3.3V logic systems. All control inputs (CS, U/D, INC) are TTL- and CMOS-compatible, with VIH ≥ 2.0V and VIL ≤ 0.8V, ensuring reliable interfacing to 3.3V microcontrollers without level shifters. Active current remains ≤3mA at 3.3V.
What is the wiper resistance specification for X9313ZMIZ at 3.3V supply?
The datasheet specifies wiper resistance (RW) as 40Ω (typ) at VCC = 5V. While not explicitly tested at 3.3V, the value scales approximately linearly with supply voltage due to CMOS switch RON dependence on VGS. At 3.3V, RW is estimated at ~26Ω (typ), contributing negligible error (<0.3%) in 1kΩ divider networks used for precision trimming.
Is X9313ZMIZ pin-compatible with other X9313 variants in MSOP-8 package?
Yes, all X9313 variants in the 8-lead MSOP package - including X9313ZMIZ, X9313WMIZ, and X9313UMIZ - share identical pinout, footprint, and solder pad layout per JEDEC MO-187-AA (drawing M8.118). Only RTOTAL (1kΩ/10kΩ/50kΩ) and temperature grade differ; electrical interface and timing remain functionally identical.
