Product details
Overview
X9315WMIZ-2.7T1 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 operates from 2.7V to 5.5V, offers 10kΩ end-to-end resistance, ±20% tolerance, 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 X9315WMIZ-2.7T1 datasheet, X9315WMIZ-2.7T1 pinout, X9315WMIZ-2.7T1 application, or X9315WMIZ-2.7T1 equivalent, this device delivers low-power CMOS operation (80µA active, 5µA standby), temperature-compensated linearity (±1 MI absolute, ±0.2 MI relative), and solid-state reliability (100,000 endurance cycles, 100-year data retention) for precision analog control in space-constrained industrial systems.
Technical Context
The X9315WMIZ-2.7T1 integrates a 5-bit up/down counter, nonvolatile EEPROM storage, and a decoder-driven wiper switching network across 31 resistive elements. Its "make-before-break" wiper transition prevents open-circuit glitches during tap changes, and the CS-controlled store operation writes the current wiper position to memory only when CS rises while INC is high.
It uses a fixed 3-wire asynchronous interface without clock line: U/D sets direction, negative-edge-triggered INC steps the wiper, and CS enables selection and initiates nonvolatile store. The wiper terminal (RW/VW) exhibits 400–1000Ω resistance at 2.7V supply, and terminal voltages are constrained to 0–VCC, with ΔVH–VL ≤ 5V absolute limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 10kΩ ±20% - defines full-scale analog adjustment range and load interaction in voltage divider configurations |
| Supply voltage range | 2.7V to 5.5V - enables direct compatibility with 3.3V and 5V logic systems without level shifting |
| Wiper positions | 32 discrete taps - provides 3.125% resolution per step for fine-grained analog parameter control |
| Active supply current | 80µA max at VCC = 5V - ensures minimal power impact in battery-backed or energy-sensitive circuits |
| Nonvolatile store time | 5–10ms - determines minimum system wait time after wiper adjustment before safe power removal |
| Operating temperature | –40°C to +85°C - qualifies for use in industrial environments without derating or thermal management |
| Wiper resistance | 400–1000Ω at 2.7V - affects insertion loss and THD in audio or sensor signal paths at low supply |
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 |
|---|---|---|
| VCC | Positive supply input | Must be ≥ VH, VL, VW; powers internal logic and resistor array; no ramp-rate restriction beyond 0.2–50 V/ms |
| VSS | Ground reference | Return path for all currents; must be common with system ground to ensure valid logic thresholds and analog referencing |
| RH/VH | High terminal | Fixed end of resistor array; voltage range 0 to VCC; polarity relative to wiper direction, not absolute potential |
| RL/VL | Low terminal | Fixed end of resistor array; voltage range 0 to VCC; complements RH/VH to define total resistance span |
| RW/VW | Wiper output | Movable tap point; series resistance 400–1000Ω at 2.7V; outputs interpolated voltage between RH and RL |
| CS | Chip select | Active-low enable; stores wiper position to EEPROM on rising edge when INC = HIGH; places device in standby when HIGH |
| U/D | Direction control | Sets wiper movement direction (up/down) during next INC edge; may change dynamically while CS = LOW |
| INC | Increment clock | Negative-edge-triggered; steps wiper one position; timing requires tIL ≥ 1µs, tIH ≥ 1µs, tCYC ≥ 4µs |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Retains last set tap position across power cycles for deterministic startup behavior without host reinitialization |
| 3-wire serial interface | Eliminates need for clock line or address decoding; reduces PCB routing complexity and GPIO count vs. I²C/SPI alternatives |
| Temperature-compensated resistor array | ±300 ppm/°C RTOTAL drift and ±20 ppm/°C ratiometric stability preserve gain/offset accuracy over industrial temperature range |
| Make-before-break wiper switching | Prevents momentary open-circuit condition during tap transitions, avoiding signal dropout or transient spikes in sensitive analog paths |
| Low standby current | 5µA max ensures negligible battery drain in always-on systems or sleep-mode operation |

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, 256-tap resolution, 10kΩ, ±30% RTOL, 2.7–5.5V | Requires I²C bus resources and supports dual independent pots; higher resolution but looser resistance tolerance | Select for multi-pot systems or when I²C infrastructure already exists; avoid if 3-wire simplicity or tighter RTOL is required |
| MCP41010-I/P | SPIM interface, single-channel, 257-tap, 10kΩ, ±20% RTOL, 2.7–5.5V, volatile wiper register only | No nonvolatile storage-wiper resets to mid-scale on power-up; requires host firmware to restore setting | Choose when cost sensitivity outweighs power-loss retention needs, or when SPI is preferred over 3-wire control |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9315WMIZ-2.7T1 uniquely combines guaranteed power-up recall, minimal 3-wire interface overhead, and industrial-grade temperature stability-making it optimal for unattended or safety-critical analog trimming where deterministic startup and long-term repeatability are essential.

FAQ
What is the maximum wiper current rating for the X9315WMIZ-2.7T1?
The X9315WMIZ-2.7T1 has a maximum wiper current rating of ±3.75mA under recommended operating conditions. This limit ensures safe operation without exceeding the 10mW maximum power rating or causing irreversible resistance drift. Exceeding this current may degrade wiper contact integrity or accelerate wear in the resistor array over time.
Does the X9315WMIZ-2.7T1 retain its wiper position after power cycling?
Yes, the X9315WMIZ-2.7T1 retains its last stored wiper position in nonvolatile EEPROM memory and automatically recalls it on power-up. This behavior occurs only if the position was explicitly stored using the CS-high-with-INC-high sequence; otherwise, the device powers up to the previously stored value, not the last volatile setting.
Can the X9315WMIZ-2.7T1 operate from a 3.3V supply?
Yes, the X9315WMIZ-2.7T1 is fully specified for operation from 2.7V to 5.5V, making it compatible with standard 3.3V logic systems. At 3.3V, its active current remains ≤80µA, wiper resistance falls within 400–1000Ω, and all timing parameters-including tCYC ≥ 4µs and tIW ≤ 5µs-remain valid.
What is the absolute linearity specification for the X9315WMIZ-2.7T1?
The X9315WMIZ-2.7T1 has an absolute linearity specification of ±1 MI (Minimum Increment), where 1 MI = RTOTAL/31 ≈ 322.6Ω for the 10kΩ version. This means the actual wiper voltage deviates by no more than ±1 MI from the ideal linear interpolation between RH and RL terminals across all 32 tap positions.
Is the X9315WMIZ-2.7T1 RoHS compliant?
Yes, the X9315WMIZ-2.7T1 is RoHS compliant and features 100% matte tin (e3) termination finish. It meets IPC/JEDEC J-STD-020 Pb-free reflow requirements and is compatible with both SnPb and lead-free soldering processes, as confirmed in Intersil's TB347 and ordering notes.
