Product details
Overview
X9315UMZ-2.7T1 from Intersil is a digitally controlled potentiometer (XDCP™) with 32-tap resolution, 50kΩ end-to-end resistance, and 2.7V to 5.5V supply operation. It implements a solid-state resistor array with nonvolatile wiper position storage, enabling precise analog parameter adjustment in low-power embedded systems such as sensor calibration and power supply feedback loops.
For engineers reviewing the X9315UMZ-2.7T1 datasheet, X9315UMZ-2.7T1 pinout, X9315UMZ-2.7T1 application, or X9315UMZ-2.7T1 equivalent, this page delivers verified specifications, package details, real-world use cases, and validated alternative options for design-in and sourcing decisions.
Technical Context
The X9315UMZ-2.7T1 uses a 5-bit up/down counter driving a 31-element resistor ladder with make-before-break wiper switching. Its control logic responds to CS (chip select), U/D (direction), and edge-triggered INC inputs to increment or decrement wiper position.
Wiper position is stored in nonvolatile EEPROM upon CS↑ while INC = HIGH, ensuring retention across power cycles. The device operates in 0°C to +70°C ambient, supports 2.7V–5.5V VCC, and maintains ±20% RTOTAL tolerance with ±300 ppm/°C temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 50kΩ ±20% - defines full-scale resistance range for voltage divider or current-limiting configurations |
| VCC Range | 2.7V to 5.5V - enables direct interface with 3.3V and 5V logic without level-shifting |
| Wiper Resolution | 32 taps (31 resistive elements) - provides ~3.1% step resolution for fine analog tuning |
| Nonvolatile Storage | 100-year data retention, 100,000 write cycles - ensures reliable factory-set or user-calibrated values survive long-term deployment |
| Active Current | 80µA max at VCC = 5V - supports battery-powered applications requiring ultra-low quiescent power |
| Wiper Resistance | 400Ω to 1000Ω at VCC = 2.7V - impacts signal integrity in high-impedance feedback paths |
| Linearity Error | ±1 MI absolute, ±0.2 MI relative - limits voltage error in precision gain-setting circuits |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), JEDEC MO-187AA / Intersil M8.118, dimensions 3.0mm × 3.0mm × 0.85mm.
| 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 currents; establishes 0V reference |
| RH/VH | High terminal | Fixed end of resistor ladder; connects to maximum potential node (e.g., VCC or reference) |
| RL/VL | Low terminal | Fixed end of resistor ladder; connects to minimum potential node (e.g., VSS or feedback node) |
| RW/VW | Wiper output | Movable tap point; delivers intermediate voltage proportional to position; series resistance affects loading |
| CS | Chip select | Active-low enable; HIGH initiates nonvolatile store when INC = HIGH; LOW enables wiper movement |
| U/D | Direction control | Logic level sets wiper increment/decrement direction during INC transitions |
| INC | Increment clock | Negative-edge triggered; advances wiper one tap per valid edge when CS = LOW |
Key Features
| Feature | Design Value |
|---|---|
| 3-wire serial interface | Requires only CS, U/D, and INC signals - eliminates need for I²C/SPI peripherals and reduces MCU GPIO count |
| Nonvolatile wiper storage | Recalls last position on power-up - eliminates boot-time reinitialization in closed-loop systems |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift - maintains stable gain or offset over industrial temperature range |
| Make-before-break switching | Prevents open-circuit wiper transitions - avoids momentary signal interruption in critical feedback paths |
| Pb-free MSOP package | RoHS-compliant 8-lead MSOP (M8.118) - supports automated SMT assembly and lead-free reflow profiles |
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 |
|---|---|---|---|
| AD5241BRMZ50 | Single-channel, I²C interface, 50kΩ, ±30% RTOTAL, 1024-tap resolution | Higher resolution but no nonvolatile store on power-up; requires external EEPROM or host initialization | Choose when I²C bus availability and finer resolution outweigh need for autonomous power-on state recovery |
| MCP41050-I/P | Single-channel, SPI interface, 50kΩ, ±20% RTOTAL, 257-tap resolution, volatile wiper register | No nonvolatile memory; wiper resets to mid-scale on power-up unless host reloads value | Choose when SPI interface is preferred and system firmware guarantees wiper reinitialization at boot |
Compared with AD5241BRMZ50 and MCP41050-I/P, the X9315UMZ-2.7T1 uniquely combines 3-wire simplicity, guaranteed power-on wiper recall, and industrial-grade temperature stability-making it optimal for unattended or safety-critical analog trimming where deterministic startup behavior is mandatory.

FAQ
What is the supply voltage range supported by the X9315UMZ-2.7T1?
The X9315UMZ-2.7T1 operates from 2.7V to 5.5V, making it compatible with both 3.3V and 5V systems. This extended range allows direct integration into mixed-voltage designs without external regulators or level shifters. The "-2.7" suffix explicitly denotes this low-voltage capability, distinguishing it from standard 5V-only variants like X9315UMZ.
Does the X9315UMZ-2.7T1 retain its wiper position after power cycling?
Yes, the X9315UMZ-2.7T1 stores the wiper position in nonvolatile EEPROM. Upon power-up, it automatically recalls the last stored value, ensuring consistent analog settings without host intervention. This behavior is guaranteed by the device's architecture and is independent of external firmware or backup power sources.
How many wiper positions does the X9315UMZ-2.7T1 provide?
The X9315UMZ-2.7T1 provides 32 discrete wiper tap points, corresponding to a 5-bit counter (0–31). These positions divide the 50kΩ end-to-end resistance into 31 equal segments, delivering ~1.61kΩ per step and enabling precise analog adjustments in applications like gain control or offset trimming.
What package type is used for the X9315UMZ-2.7T1?
The X9315UMZ-2.7T1 is housed in an 8-lead MSOP (Mini Small Outline Plastic) package, RoHS-compliant and Pb-free, with JEDEC MO-187AA footprint (Intersil M8.118). Its compact 3.0mm × 3.0mm body supports high-density PCB layouts and standard reflow soldering processes.
Can the X9315UMZ-2.7T1 be used as a two-terminal variable resistor?
Yes, the X9315UMZ-2.7T1 can operate as a two-terminal variable resistor by connecting either RH/VH or RL/VL to RW/VW and leaving the unused terminal open or grounded. In this mode, it functions as a digitally adjustable current-limiting or bias-setting element, maintaining the same 32-step resolution and nonvolatile storage capability.
