Product details
Overview
X9315UMIZ-2.7T1 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, offers 50kΩ end-to-end resistance, −40°C to +85°C industrial temperature range, and is housed in an 8-lead Pb-free MSOP package. It serves as a solid-state replacement for mechanical potentiometers in precision analog trimming applications.
For engineers reviewing the X9315UMIZ-2.7T1 datasheet, X9315UMIZ-2.7T1 pinout, X9315UMIZ-2.7T1 application, or X9315UMIZ-2.7T1 equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial-grade operating conditions, and real-world use cases in voltage divider and variable resistor configurations - all grounded in the FN8179 Rev.2.00 datasheet.
Technical Context
The X9315UMIZ-2.7T1 uses a 5-bit up/down counter driving a decoder that selects one of 32 wiper taps across a monolithic 31-resistor array. Wiper position is stored in nonvolatile EEPROM upon CS↑ while INC = HIGH, enabling power-up recall without external memory.
Its 3-wire interface operates with make-before-break switching, supports 2.7V–5.5V supply, and features low active current (80µA max at VCC = 2.7V), 5µA standby current, and ±3.75mA max wiper current. Temperature-compensated design yields ±300ppm/°C total resistance drift and ±20% end-to-end tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 50kΩ ±20% - defines full-scale analog adjustment range and load interaction in voltage divider circuits |
| Supply voltage range | 2.7V to 5.5V - enables direct compatibility with 3.3V and 5V systems without level-shifting |
| Wiper positions | 32 discrete taps - provides 3.125% resolution per step for fine-grained analog control |
| Nonvolatile storage | 100-year data retention, 100,000 write cycles - ensures reliable factory calibration and user-set parameter persistence across power cycles |
| Operating temperature | −40°C to +85°C - qualified for industrial environments including motor controls and sensor signal conditioning |
| Active supply current | 80µA max at 2.7V - minimizes system power budget impact during dynamic wiper adjustment |
| Wiper resistance | 400Ω to 1000Ω at 2.7V - impacts insertion loss and THD in audio or precision gain-setting paths |
Pinout & Package
Package: 8-lead Mini Small Outline Plastic (MSOP), Pb-free, JEDEC MO-187AA compliant (Package Drawing M8.118), 3.0mm × 3.0mm footprint, 0.65mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RH/VH | High terminal | Fixed end of resistor array; connects to highest potential node (up to VCC); referenced in wiper voltage calculation |
| 2 - RW/VW | Wiper terminal | Movable output node; delivers tapped voltage/current; series resistance 400–1000Ω at 2.7V affects signal integrity |
| 3 - RL/VL | Low terminal | Fixed end of resistor array; connects to lowest potential node (down to VSS); completes resistive divider path |
| 4 - VSS | Ground | Reference return for internal logic and resistor array; must be low-impedance to minimize noise coupling |
| 5 - VCC | Supply voltage | Power rail for digital control logic and analog array; accepts 2.7V–5.5V; must ramp ≥0.2V/ms |
| 6 - U/D | Up/down direction control | Logic-level input determining wiper increment/decrement on each INC edge; may change dynamically during CS active |
| 7 - INC | Increment clock | Negative-edge-triggered; advances wiper one tap per valid edge; HIGH during CS↑ initiates nonvolatile store |
| 8 - CS | Chip select | Active-low enable; device responds only when LOW; rising edge with INC = HIGH triggers EEPROM store and standby entry |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, contact bounce, and vibration sensitivity - critical for long-life embedded instrumentation |
| 3-wire serial interface | Requires only three GPIOs (CS/U/D/INC) - simplifies microcontroller integration without SPI/I²C peripherals |
| Nonvolatile wiper position storage | Recalls last setting at power-up - enables consistent startup behavior in unattended systems like HVAC controllers |
| Temperature-compensated resistor array | ±300ppm/°C RTOTAL drift - maintains gain/offset stability across industrial temperature ranges |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions - avoids signal dropout in audio or sensor bias networks |

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, 256-tap resolution, 2.7–5.5V | Higher resolution but requires I²C bus and external pull-ups; no native power-up recall without firmware | Select when higher granularity and multi-device addressing are needed; avoid if GPIO-constrained or EEPROM recall is mandatory |
| MCP41050-I/P | Single-channel, SPI interface, 50kΩ, 257-tap resolution, 2.7–5.5V, volatile wiper register | Volatile-only storage; requires external MCU to reload wiper position after power-up | Select for cost-sensitive designs where power-up state is managed by host firmware; not suitable for standalone calibration retention |
Compared with AD5241BRMZ50 and MCP41050-I/P, the X9315UMIZ-2.7T1 uniquely combines 3-wire simplicity, guaranteed power-up recall, and industrial temperature qualification - making it optimal for self-contained analog trimming where bus overhead or external initialization is undesirable.

FAQ
What is the supply voltage range for the X9315UMIZ-2.7T1?
The X9315UMIZ-2.7T1 operates from 2.7V to 5.5V, as specified in the FN8179 Rev.2.00 datasheet. This dual-voltage capability allows direct use in both 3.3V and 5V systems without external regulators. The "-2.7" suffix explicitly denotes this extended low-voltage rating, distinguishing it from standard 5V-only variants like X9315UMIZ.
Does the X9315UMIZ-2.7T1 retain its wiper position after power cycling?
Yes, the X9315UMIZ-2.7T1 stores the wiper position in nonvolatile EEPROM memory. Upon power-up, it automatically recalls the last stored value - a feature confirmed in the datasheet's "Principles of Operation" and "Power-up and Down Requirements" sections. This behavior is intrinsic to the X9315UMIZ-2.7T1 and does not require host intervention.
What package type is used for the X9315UMIZ-2.7T1?
The X9315UMIZ-2.7T1 is supplied in an 8-lead Mini Small Outline Plastic (MSOP) package, Pb-free and RoHS-compliant, with JEDEC MO-187AA outline (drawing M8.118). Its dimensions are 3.0mm × 3.0mm with 0.65mm lead pitch - verified in the "Ordering Information" and "Package Outline Drawing" sections of FN8179 Rev.2.00.
How many wiper tap positions does the X9315UMIZ-2.7T1 support?
The X9315UMIZ-2.7T1 provides 32 discrete wiper tap positions, corresponding to a 5-bit counter (2⁵ = 32). This is explicitly stated in the datasheet title ("32 Taps Digitally Controlled Potentiometer") and confirmed in the "Principles of Operation" section, where the 31-resistor array yields 32 accessible nodes including both ends.
What is the end-to-end resistance value of the X9315UMIZ-2.7T1?
The X9315UMIZ-2.7T1 has a nominal end-to-end resistance (RTOTAL) of 50kΩ, with a tolerance of ±20%, as documented in the "Ordering Information" table and "Potentiometer Characteristics" section of FN8179 Rev.2.00. This value is fixed per device variant and is independent of supply voltage or temperature within specification limits.
