Product details
Overview
X9315TMZ-2.7 from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 31-element resistor array with 32 wiper tap positions, nonvolatile wiper position storage, and 3-wire serial interface (CS/U/D/INC). It operates from 2.7V to 5.5V, delivers 100kΩ end-to-end resistance ±20%, and supports commercial temperature range (0°C to +70°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 X9315TMZ-2.7 datasheet, X9315TMZ-2.7 pinout, X9315TMZ-2.7 application, or X9315TMZ-2.7 equivalent, this page provides verified specifications including VCC range (2.7–5.5V), RTOTAL (100kΩ), wiper resolution (32 taps), nonvolatile store/recall behavior, and MSOP-8 package dimensions - all confirmed from Intersil FN8179 Rev.2.00.
Technical Context
The X9315TMZ-2.7 uses a 5-bit up/down counter driving a decoder that selects one of 32 wiper positions across a segmented 31-resistor array. Wiper movement is controlled by edge-triggered INC input with direction set by U/D logic level, and nonvolatile storage occurs on CS↑ while INC = HIGH.
It features make-before-break switching during wiper transitions, temperature-compensated resistive elements (±300 ppm/°C RTOTAL drift), and low-power CMOS operation: active current ≤80 µA at 2.7V, standby current ≤5 µA. Terminal voltages are rail-to-rail (0 to VCC), and wiper resistance is 400–1000 Ω at 2.7V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 100kΩ ±20% - defines full-scale resistance for voltage divider or current-limiting use |
| VCC Range | 2.7V to 5.5V - enables direct interface with 2.7V/3.3V/5V logic and mixed-supply systems |
| Wiper Positions | 32 discrete taps - provides ~3% resolution per step (1/31 increment) |
| Nonvolatile Store | 100-year data retention, 100,000 write cycles - eliminates need for external EEPROM or boot-time calibration |
| Active Current | ≤80 µA at 2.7V - supports battery-powered or ultra-low-power analog front-end designs |
| Wiper Resistance | 400–1000 Ω at 2.7V - impacts loading error in high-impedance feedback paths |
| Temp Range | 0°C to +70°C - qualified for commercial-grade embedded control and consumer electronics |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), JEDEC MO-187BA / Intersil M8.118, body dimensions 3.0mm × 3.0mm × 0.95mm, lead pitch 0.65mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Must be ≥ VH, VL, VW; powers internal logic and resistor array |
| VSS | Ground reference | Return path for supply and signal terminals; establishes 0V baseline |
| RH/VH | High terminal | Fixed end of resistor string; connects to maximum potential in voltage divider |
| RL/VL | Low terminal | Fixed end of resistor string; connects to minimum potential (e.g., VSS) |
| RW/VW | Wiper output | Movable tap point; delivers intermediate voltage/current based on stored position |
| CS | Chip Select | Active-low enable; initiates communication and triggers nonvolatile store on rising edge with INC = HIGH |
| U/D | Up/Down direction control | Sets wiper movement direction (HIGH = increment, LOW = decrement) during INC transitions |
| INC | Increment clock input | Negative-edge triggered; advances wiper position when CS = LOW and U/D sets direction |
Key Features
| Feature | Design Value |
|---|---|
| 3-wire serial interface | Requires only CS, U/D, and INC signals - eliminates need for I²C/SPI peripherals or address decoding logic |
| Nonvolatile wiper storage | Retains last position across power cycles - ensures repeatable startup behavior without host MCU initialization |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift - maintains stable gain/attenuation over ambient temperature variations |
| Rail-to-rail terminal voltage | VH/VL/VW operate from 0V to VCC - supports full dynamic range in single-supply op-amp circuits |
| Make-before-break switching | Prevents open-circuit transients during wiper motion - avoids glitches in sensitive analog signal paths |
Applications
| Audio Volume Control | Laser Diode Bias Adjustment |
|---|---|
|
Use Scenario: Precise attenuation of line-level audio signals in portable media players or USB DACs with no mechanical wear. IC Role / Device Role / Timing Role: Three-terminal potentiometer configured as voltage divider between input and ground, with wiper feeding op-amp input.

| Power Supply Feedback Trimming | Sensor Signal Offset Compensation |
|
Use Scenario: Factory-trimming output voltage of DC-DC converters in industrial PLC modules before deployment. IC Role / Device Role / Timing Role: Adjustable resistor in resistor divider network feeding voltage feedback pin of regulator IC. Use Value: Nonvolatile store enables one-time calibration; 2.7V operation matches low-voltage control rails in modern SMPS controllers. |
Use Scenario: Nulling offset voltage in bridge-based pressure sensor interfaces used in HVAC control systems. IC Role / Device Role / Timing Role: Two-terminal variable resistor in Wheatstone bridge leg to balance differential output at zero pressure. Use Value: Low 5 µA standby current minimizes system quiescent draw; ±20% RTOTAL tolerance accommodates batch calibration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ10 | I²C interface, dual-channel, 10kΩ, ±30% RTOTAL, 2.7–5.5V | Requires I²C master; supports simultaneous dual-pot control; tighter VCC min but wider RTOTAL tolerance | Select when dual independent pots or standard I²C bus integration is required; not drop-in due to protocol and pinout mismatch |
| MCP45HV51-103E/MS | Single-wiper, SPI interface, 10kΩ, ±20%, 4.5–18V supply | Higher voltage rating enables use in 12V analog systems; SPI offers faster update rate but adds CS/SCK/MOSI pins | Choose for high-voltage analog trimming (e.g., motor control feedback); incompatible pinout and interface prevent direct replacement |
Compared with AD5243BRMZ10 and MCP45HV51-103E/MS, the X9315TMZ-2.7 offers simpler 3-wire control with guaranteed nonvolatile recall at 2.7V, making it optimal for cost-sensitive, single-pot, low-voltage embedded trimming where minimal GPIO usage is critical.

FAQ
What is the exact end-to-end resistance value and tolerance for X9315TMZ-2.7?
The X9315TMZ-2.7 has a nominal end-to-end resistance (RTOTAL) of 100kΩ with a tolerance of ±20%, as specified in the Intersil FN8179 datasheet ordering table and confirmed in the Potentiometer Characteristics section. This tolerance applies across the full operating temperature range (0°C to +70°C) and is production-tested at +25°C.
Does X9315TMZ-2.7 retain its wiper position after power cycling?
Yes, the X9315TMZ-2.7 stores the wiper position in nonvolatile memory upon command (CS↑ with INC = HIGH) and automatically recalls it at power-up. Data retention is rated for 100 years, and endurance is 100,000 store cycles - both confirmed in the Endurance and Data Retention section of the FN8179 datasheet.
What package type and footprint does X9315TMZ-2.7 use?
The X9315TMZ-2.7 uses an 8-lead MSOP package (JEDEC MO-187BA / Intersil M8.118), Pb-free and RoHS compliant. Its dimensions are 3.0mm × 3.0mm × 0.95mm with 0.65mm lead pitch. The package drawing and mechanical tolerances are fully documented on page 13 of FN8179 Rev.2.00.
Can X9315TMZ-2.7 operate from a 2.7V supply only, or does it require 5V?
The X9315TMZ-2.7 is explicitly rated for VCC = 2.7V to 5.5V, as stated in the Recommended Operating Conditions table (page 6) and Ordering Information (page 2) of FN8179. It draws ≤80 µA active current at 2.7V and supports full functionality - including wiper movement, store, and recall - at the minimum supply voltage.
How many wiper positions does X9315TMZ-2.7 provide, and what is the resolution?
The X9315TMZ-2.7 provides exactly 32 wiper tap positions, corresponding to a 5-bit counter (2⁵ = 32). Resolution is defined by the minimum increment (MI) of RTOTAL/31 ≈ 3.226kΩ per step for 100kΩ devices, yielding ~3% step size - confirmed in the Potentiometer Characteristics table (page 6) and Principles of Operation (page 4).
