Product details
Overview
X9315TMIZ from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 31-element resistor array with 32 wiper tap positions, nonvolatile memory for power-up recall, and 3-wire serial interface (CS/U/D/INC). It delivers 100kΩ end-to-end resistance, ±20% tolerance, operates from 4.5V to 5.5V, and supports industrial temperature range (–40°C to +85°C) in an 8-lead MSOP package. It functions as a three-terminal voltage divider or two-terminal variable resistor in analog signal trimming applications.
For engineers reviewing the X9315TMIZ datasheet, X9315TMIZ pinout, X9315TMIZ application, or X9315TMIZ equivalent, key selection criteria include its 100kΩ RTOTAL value, nonvolatile wiper position storage, 5-bit up/down counter control logic, low standby current (5µA), and compatibility with 5V CMOS-level digital interfaces in precision analog adjustment circuits.
Technical Context
The X9315TMIZ integrates a 5-bit up/down counter, 5-bit nonvolatile memory, and a 31-resistor ladder with make-before-break wiper switching. Wiper position is updated on negative-edge transitions of INC while CS is active, with direction determined by U/D logic level.
It stores wiper settings in EEPROM upon CS rising edge with INC high (tWR = 5–10ms), retains data for 100 years, and endures 100,000 write cycles. Terminal voltages are limited to 0–VCC, and wiper resistance is 200Ω (typ.) at VCC = 5V, enabling direct connection to op-amp inputs or reference nodes without buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 100kΩ ±20% - defines full-scale resistance range for voltage division or current limiting in analog circuits |
| Wiper taps | 32 positions (0–31) - provides 3.125% resolution per step across full resistance range |
| VCC range | 4.5V to 5.5V - compatible with standard 5V logic and analog supply rails |
| Operating temp | –40°C to +85°C - qualified for industrial-grade embedded systems and instrumentation |
| Standby current | 5µA max - enables low-power operation during system sleep modes |
| Wiper resistance | 200Ω typ. at 5V - low enough to avoid significant voltage error in high-impedance feedback paths |
| Nonvolatile store | 100-year retention, 100k-cycle endurance - ensures reliable recalibration after power cycling |
Pinout & Package
Package: 8-lead MSOP (Pb-free), JEDEC MO-187AA compliant, body dimensions 3.0mm × 3.0mm × 0.85mm (M8.118 drawing).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RH/VH | High terminal | Fixed end of resistor array; connects to maximum potential (VCC) in voltage divider configuration |
| RL/VL | Low terminal | Fixed end of resistor array; connects to minimum potential (VSS) in voltage divider configuration |
| RW/VW | Wiper terminal | Movable tap point; output node whose voltage scales linearly between VH and VL based on counter value |
| VCC | Supply voltage | Positive supply rail (4.5–5.5V); powers internal logic and resistor array |
| VSS | Ground | Reference ground for all analog and digital circuitry |
| CS | Chip Select | Active-low enable; initiates wiper movement when low; triggers nonvolatile store on rising edge with INC high |
| U/D | Up/Down control | Determines wiper direction: HIGH = increment, LOW = decrement on next INC edge |
| INC | Increment input | Negative-edge-triggered clock; advances wiper position in direction set by U/D when CS is low |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer | Eliminates mechanical wear, contact bounce, and drift-enables >100k lifetime adjustments in automated calibration |
| 3-wire serial interface | Minimal GPIO usage (CS/U/D/INC) - simplifies integration with microcontrollers lacking SPI peripherals |
| Nonvolatile wiper storage | Power-up restores last stored setting - removes need for host MCU initialization sequence or external EEPROM |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift - maintains stable gain/offset in ambient temperature variations |
| Make-before-break switching | Prevents open-circuit transients during wiper movement - avoids glitches in sensitive op-amp feedback loops |
Applications
| Audio Signal Level Control | DC Power Supply Feedback Trimming |
|---|---|
|
Use Scenario: Adjusting volume or balance in analog audio paths without mechanical knobs or relay-based switching. IC Role / Device Role / Timing Role: Acts as a digitally programmable voltage divider between audio source and amplifier input. Use Value: Enables remote or automated gain control with 32-step resolution and zero-contact wear over decades of use. |
Use Scenario: Fine-tuning output voltage of adjustable DC-DC converters or linear regulators during production calibration. IC Role / Device Role / Timing Role: Replaces manual trimmer in feedback divider network (e.g., TL431-based supplies). Use Value: Allows factory-programmed output voltage with permanent storage-no re-trimming required after power loss. |
| Laser Diode Bias Current Adjustment | Industrial Sensor Offset Calibration |
|
Use Scenario: Setting precise bias current for laser diodes in optical transceivers or medical instruments. IC Role / Device Role / Timing Role: Two-terminal variable resistor in constant-current source configuration (e.g., with op-amp and MOSFET). Use Value: Provides stable, repeatable current setting unaffected by vibration or thermal cycling-critical for wavelength stability. |
Use Scenario: Compensating zero-point offset in strain gauge, thermistor, or RTD signal conditioning circuits. IC Role / Device Role / Timing Role: Adjustable reference leg in Wheatstone bridge or instrumentation amplifier gain/offset network. Use Value: Enables one-time calibration at end-of-line test with nonvolatile retention-eliminates field recalibration needs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ100 | 2-channel I²C interface, 100kΩ, 256-tap resolution, 1.8–5.5V supply | Higher resolution and dual-channel capability; requires I²C bus instead of 3-wire logic | Select when multi-channel trimming or finer adjustment granularity is needed and I²C infrastructure exists |
| MCP41010-I/P | Single-channel SPI interface, 10kΩ, 257-tap resolution, 2.7–5.5V supply | Lower RTOTAL, higher resolution, SPI protocol, no nonvolatile store on power-up (requires external command) | Select when SPI is preferred and persistent power-up state is managed externally via MCU firmware |
Compared with AD5243BRMZ100 and MCP41010-I/P, the X9315TMIZ offers guaranteed power-up to last stored value without host intervention, simpler 3-wire control, and industrial temperature rating-but with coarser 32-step resolution and fixed 100kΩ value.

FAQ
What is the supply voltage range for the X9315TMIZ?
The X9315TMIZ operates from 4.5V to 5.5V (5V ±10%). It is not rated for 2.7V operation-unlike some variants in the X9315 family (e.g., X9315TMIZ-2.7), the X9315TMIZ is specified only for 5V nominal supply. Exceeding this range may cause functional failure or reduced reliability.
Does the X9315TMIZ retain its wiper position after power cycling?
Yes, the X9315TMIZ automatically recalls the last stored wiper position from nonvolatile memory upon power-up. This behavior is guaranteed and requires no host MCU action. The position is stored only when CS rises while INC is high-a deliberate store command-not on every wiper movement.
What package type is used for the X9315TMIZ?
The X9315TMIZ uses an 8-lead MSOP (Mini Small Outline Package) with Pb-free (RoHS-compliant) finish, per JEDEC MO-187AA specification (drawing M8.118). Its footprint measures 3.0mm × 3.0mm, with 0.65mm lead pitch and exposed pad not present.
How many wiper positions does the X9315TMIZ support?
The X9315TMIZ supports exactly 32 discrete wiper positions (0 through 31), corresponding to a 5-bit counter. Each position represents one tap point across the 31-resistor array, yielding ~3.125% resolution per step relative to full-scale resistance.
Can the X9315TMIZ be used as a two-terminal variable resistor?
Yes, the X9315TMIZ can operate as a two-terminal variable resistor by connecting either RH/VH or RL/VL to RW/VW and using the remaining terminal plus RW/VW. This configuration is explicitly supported in the datasheet and commonly used in current-setting or gain-adjustment circuits where only one adjustable node is required.
