Product details
Overview
X9315WMIZ-2.7T1R5419 from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 31-element resistor array with 32 wiper tap points, 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 serves as a solid-state replacement for mechanical potentiometers in precision analog trimming applications.
For engineers reviewing the X9315WMIZ-2.7T1R5419 datasheet, X9315WMIZ-2.7T1R5419 pinout, X9315WMIZ-2.7T1R5419 application, or X9315WMIZ-2.7T1R5419 equivalent, this page delivers verified specifications including wiper resistance (400–1000Ω at 2.7V), absolute linearity (±1 MI), ratiometric tempco (±20 ppm/°C), noise (–120 dBV), and EEPROM endurance (100,000 cycles).
Technical Context
The X9315WMIZ-2.7T1R5419 uses a 5-bit up/down counter driving a decoder that selects one of 32 wiper positions across a monolithic 31-resistor ladder. Its control logic implements make-before-break switching and stores wiper position in nonvolatile memory only when CS rises while INC is HIGH - enabling deterministic power-up behavior without unintended writes.
It features temperature-compensated resistive elements, supports terminal voltages from VSS to VCC, and maintains wiper stability during power transitions provided VCC ≥ VH, VL, VW. The device draws ≤5µA standby current and ≤400µA during EEPROM store operations, making it suitable for low-power embedded systems requiring persistent analog calibration.
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 |
| Wiper resistance | 400–1000Ω at VCC = 2.7V - impacts signal integrity and loading error when used as variable gain or bias element |
| Supply voltage range | 2.7V to 5.5V - enables direct compatibility with 3.3V and 5V logic domains without level shifting |
| Temperature range | –40°C to +85°C - qualified for industrial-grade operation in automotive ECUs, sensor signal conditioning, and factory automation |
| Nonvolatile memory endurance | 100,000 data changes per bit - supports frequent recalibration in field-deployed equipment over multi-year service life |
| Absolute linearity error | ±1 MI (Minimum Increment = RTOTAL/31 ≈ 322Ω) - ensures predictable stepwise voltage division across all 32 taps |
| Ratiometric tempco | ±20 ppm/°C - guarantees stable voltage division ratio independent of supply drift or ambient temperature shifts |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), JEDEC MO-187AA / Intersil M8.118, body dimensions 3.0mm × 3.0mm × 0.85mm, thermal resistance θJA = 154°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Must be ≥ VH, VL, VW; powers internal logic and resistor array; supports 2.7V–5.5V operation |
| VSS | Ground reference | Return path for supply and signal currents; establishes 0V baseline for RH/VH and RL/VL terminals |
| RH/VH | High terminal | Fixed end of resistor array; voltage ranges from VSS to VCC; not polarity-fixed - role depends on U/D direction |
| RL/VL | Low terminal | Fixed end of resistor array; voltage ranges from VSS to VCC; complementary to RH/VH in wiper movement direction |
| RW/VW | Wiper output | Movable terminal; connects to one of 32 tap points; series resistance 400–1000Ω at 2.7V affects output impedance |
| CS | Chip select | Active-low enable; rising edge with INC = HIGH triggers nonvolatile store; high state places device in standby (5µA) |
| U/D | Direction control | Sets wiper increment/decrement direction during INC toggling; may change dynamically while CS = LOW |
| INC | Increment clock | Negative-edge triggered; each pulse moves wiper one position; HIGH during CS rise initiates EEPROM store |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Recalls last-set tap position on power-up - eliminates need for host MCU initialization sequence or external EEPROM |
| 3-wire serial interface | Requires only CS, U/D, and INC signals - reduces GPIO count vs. SPI/I²C; no clock line needed |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions - critical for stable biasing in amplifier feedback networks |
| Low power operation | 400µA max active current during store, 5µA standby - extends battery life in portable instrumentation and IoT sensors |
| Industrial temperature rating | –40°C to +85°C operation - validated for use in motor drives, PLC I/O modules, and outdoor environmental monitors |
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 |
|---|---|---|---|
| AD5175BRMZ-10 | 256-tap I²C interface; 10kΩ; ±8% RTOTAL tolerance; 10ppm/°C tempco; 500k-cycle EEPROM | Higher resolution and tighter specs but requires I²C bus and occupies more PCB area (10-lead MSOP) | Select when finer adjustment granularity, lower tempco, or I²C system integration outweighs cost and footprint increase |
| MCP41010-I/P | 256-tap SPI interface; 10kΩ; ±20% RTOTAL; no nonvolatile memory - wiper resets to mid-scale on power-up | Lacks power-up recall; requires host MCU to reinitialize wiper position at boot | Choose for cost-sensitive designs where calibration is performed at startup and no persistent settings are required |
Compared with AD5175BRMZ-10 and MCP41010-I/P, the X9315WMIZ-2.7T1R5419 offers deterministic power-up behavior without host intervention, minimal GPIO usage (3-wire), and industrial temperature support - making it optimal for standalone analog trimming where reliability and simplicity are prioritized over ultra-fine resolution.

FAQ
What is the maximum wiper current rating for the X9315WMIZ-2.7T1R5419?
The X9315WMIZ-2.7T1R5419 has a maximum wiper current rating of ±3.75mA under recommended operating conditions. This limit ensures safe operation within the 10mW maximum power rating and prevents degradation of the internal resistor array or wiper switches. Exceeding this current may cause irreversible resistance drift or open-circuit failure.
Does the X9315WMIZ-2.7T1R5419 retain its wiper position after power loss?
Yes, the X9315WMIZ-2.7T1R5419 stores the wiper position in nonvolatile memory and automatically recalls it on power-up. This occurs only if the position was explicitly stored by raising CS while INC is HIGH - the device does not auto-store on power-down. Once recalled, the wiper is stable within 5µs (tPU).
Can the X9315WMIZ-2.7T1R5419 be used with a 3.3V microcontroller GPIO interface?
Yes, the X9315WMIZ-2.7T1R5419 is fully compatible with 3.3V logic. Its VIH threshold is VCC × 0.7 (min 1.89V at 2.7V supply), and VIL is VCC × 0.1 (max 0.55V), ensuring reliable recognition of 3.3V GPIO HIGH/LOW levels. No level-shifting circuitry is required.
What is the typical wiper resistance of the X9315WMIZ-2.7T1R5419 at 2.7V supply?
The typical wiper resistance of the X9315WMIZ-2.7T1R5419 is 400Ω at VCC = 2.7V, with a maximum of 1000Ω. This value directly impacts output impedance in voltage divider configurations and must be accounted for in precision gain-setting or bias network calculations.
Is the X9315WMIZ-2.7T1R5419 RoHS compliant and lead-free?
Yes, the X9315WMIZ-2.7T1R5419 is RoHS compliant and Pb-free, using 100% matte tin plate (e3 termination finish) and Pb-free molding compounds. It meets IPC/JEDEC J-STD-020 reflow profiles and is rated MSL1 - suitable for standard lead-free assembly processes.
