Product details
Overview
X9313ZM-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 and functions as a solid-state replacement for mechanical potentiometers in precision analog trimming applications.
For engineers reviewing the X9313ZM-3 datasheet, X9313ZM-3 pinout, X9313ZM-3 application, or X9313ZM-3 equivalent, key selection criteria include its 1kΩ RTOTAL tolerance (±20%), wiper resistance (40Ω typ. at 5V), 100,000-cycle endurance, 100-year data retention, and MSOP-8 package compatibility with industrial temperature range (0°C to +70°C).
Technical Context
The X9313ZM-3 implements a 31-element resistor array with make-before-break wiper switching, controlled by a 5-bit up/down counter decoded to select one of 32 tap points. Its nonvolatile memory stores wiper position on CS↑ with INC HIGH, enabling automatic recall at power-up.
Operation requires VCC/VSS applied before terminal voltages; wiper movement is edge-triggered on INC with direction set by U/D, and timing parameters include tIW = 5µs (INC to VW change) and tCPH = 20ms for store cycle completion. Terminal voltage range spans –VCC to +VCC, supporting bipolar signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 1kΩ ±20% - defines full-scale resistance range for voltage divider or current-limiting use |
| Wiper Resistance | 40Ω typical at VCC = 5V - contributes minimal series impedance in wiper path |
| VCC Range | 3V to 5.5V - supports dual-supply systems and 3.3V/5V logic compatibility |
| Terminal Voltage Range | –VCC to +VCC - enables bipolar operation (e.g., ±5V signal paths) |
| Endurance | 100,000 data changes per bit - ensures long-term reliability in dynamic adjustment loops |
| Data Retention | 100 years - maintains factory or user-set trim values across product lifecycle |
| Resolution | 3% - corresponds to 1/31 step size (MI = RTOTAL/31 ≈ 32.3Ω) |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), dimensions per JEDEC MO-187-AA (M8.118), body size 3.0mm × 3.0mm × 1.1mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Power source for internal logic and resistor array; must be stable before applying terminal voltages |
| VSS | Ground reference | Common return for supply and control signals; establishes 0V reference for all terminals |
| RH/VH | High terminal | Fixed end of resistor array; voltage polarity relative to wiper depends on U/D state, not absolute potential |
| RL/VL | Low terminal | Fixed end opposite RH/VH; forms complete resistive path with RH/VH and RW/VW |
| RW/VW | Wiper terminal | Movable contact point; output voltage varies linearly with tap position; series resistance ~40Ω |
| CS | Chip select | Active-low enable; initiates communication and triggers nonvolatile store when raised HIGH with INC HIGH |
| U/D | Direction control | Sets wiper movement direction (up/down) during INC transitions; may change dynamically while CS is LOW |
| INC | Increment clock | Negative-edge triggered; advances wiper one tap per pulse; timing critical (tIL/tIH ≥1µs, tCYC ≥2µs) |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last programmed position across power cycles without external backup power |
| 3-wire serial interface | Minimizes GPIO count vs. SPI/I²C; uses only CS, U/D, and edge-triggered INC |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift - maintains ratio accuracy over 0°C to +70°C range |
| Make-before-break switching | Prevents open-circuit transients during wiper movement; avoids signal dropout in active circuits |
| Bipolar terminal voltage support | Accepts –VCC to +VCC on RH/VH and RL/VL - enables AC-coupled and dual-supply analog designs |

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-tap resolution, 2.7–5.5V supply | Higher resolution but incompatible interface and resistance value; requires pull-up resistors and protocol stack | Select if I²C bus integration and finer adjustment granularity outweigh redesign effort |
| MCP41010-I/P | 10kΩ RTOTAL, SPI interface, 257-tap resolution, 2.7–5.5V supply, no nonvolatile memory | Lacks power-on recall; requires external MCU to reinitialize wiper position after each reset | Choose when higher resolution is critical and system firmware can manage persistent state |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9313ZM-3 offers guaranteed power-up to last stored setting, minimal GPIO usage (3-wire), and 1kΩ resistance optimized for low-noise, low-current bias networks - making it ideal for space-constrained, self-initializing analog trim tasks.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313ZM-3?
The X9313ZM-3 supports a maximum differential voltage ΔV = |VH − VL| of 4V, as specified for the X9313Z variant in the Absolute Maximum Ratings table. This limit applies regardless of VCC level and must not be exceeded to prevent damage to the internal resistor array or switching elements.
Does X9313ZM-3 require an external power-on reset circuit to ensure reliable initialization?
No, X9313ZM-3 does not require an external power-on reset circuit. Upon power-up, it automatically recalls the last stored wiper position from nonvolatile memory within 10µs (tPU), provided VCC has stabilized. The recommended sequence-applying VCC/VSS before terminal voltages-ensures correct behavior without additional hardware.
Can X9313ZM-3 be used in a two-terminal variable resistor configuration?
Yes, X9313ZM-3 can be configured as a two-terminal variable resistor by connecting either RH/VH or RL/VL to RW/VW and using the remaining fixed terminal plus wiper. This configuration leverages the same 32-tap resolution and nonvolatile storage, but total resistance varies from 0Ω to RTOTAL (1kΩ) depending on wiper position.
What is the wiper current rating for X9313ZM-3, and how does it affect design margins?
The X9313ZM-3 specifies a maximum wiper current IW of ±4.4mA. At 1kΩ RTOTAL and 4V max ΔV, this corresponds to a worst-case power dissipation of ~17.6mW in the wiper switch - well below the 16mW rating for 1kΩ devices. Designers must ensure that external circuitry limits current through RW/VW to stay within this bound under all operating conditions.
Is the X9313ZM-3 pin-compatible with other members of the X9313 family in MSOP-8 packages?
Yes, all X9313 variants in the 8-lead MSOP package-including X9313ZM-3, X9313ZMIZ-3, and X9313WMZ-3-share identical pinout, footprint, and electrical interface. Differences are limited to RTOTAL (1kΩ vs. 10kΩ), temperature range (0°C to +70°C vs. –40°C to +85°C), and VCC range (3–5.5V), allowing direct substitution where those parameters align with system requirements.
