Product details
Overview
X9315TMZT1 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 at 5V ±10%, delivers 100kΩ end-to-end resistance with ±20% tolerance, and supports commercial temperature range (0°C to +70°C) in an 8-lead MSOP package. It functions as a solid-state replacement for mechanical potentiometers in precision analog trimming applications.
For engineers reviewing the X9315TMZT1 datasheet, X9315TMZT1 pinout, X9315TMZT1 application, or X9315TMZT1 equivalent, this device is selected for low-noise, low-power analog adjustment where nonvolatile setting retention, temperature-compensated linearity, and CMOS-compatible digital control are required - especially in voltage divider, gain-setting, and offset calibration circuits.
Technical Context
The X9315TMZT1 uses a 5-bit up/down counter driving a decoder that selects one of 32 wiper positions across a monolithic 31-resistor ladder. Wiper movement follows make-before-break switching, preventing open-circuit transients during tap transitions. Its nonvolatile memory stores the last wiper position upon CS↑ with INC↑, enabling automatic restoration at power-up.
It features temperature-compensated resistor elements with ±300 ppm/°C total resistance drift and ±20 ppm/°C ratiometric coefficient, ensuring stable voltage division over temperature. Terminal voltage range spans 0 V to VCC, and wiper resistance is 200 Ω (typ.) at 5 V, supporting ≤±3.75 mA wiper current per specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 100 kΩ ±20% - defines full-scale analog adjustment range and sets minimum load impedance for stable divider operation |
| Wiper positions | 32 discrete taps - provides 3.125% resolution per step (1/31) for precise analog parameter tuning |
| Supply voltage | 5 V ±10% - compatible with standard 5 V logic and analog rails; no support for 2.7 V operation per ordering table |
| Active supply current | 80 µA max - enables battery-powered or low-quiescent systems without compromising update speed |
| Standby current | 5 µA max - ensures minimal leakage during idle periods, critical for energy-sensitive designs |

Pinout & Package
Package: 8-lead MSOP (Pb-free), JEDEC MO-187AA compliant, body dimensions 3.0 mm × 3.0 mm × 0.85 mm (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 reverse polarity tolerance |
| VSS | Ground reference | Common return for all signals and internal circuitry; must be connected before applying VCC |
| RH/VH | High terminal | Fixed end of resistor array; voltage range 0 V to VCC; not polarity-referenced but positionally defined by U/D direction |
| RL/VL | Low terminal | Fixed opposite end of resistor array; same voltage constraints as RH/VH; forms full RTOTAL path with RH |
| RW/VW | Wiper output | Movable tap point; series resistance ~200 Ω affects output impedance and signal fidelity in buffered/unbuffered use |
| CS | Chip select | Active-low enable; wiper position stored to NV memory on rising edge when INC = HIGH |
| U/D | Direction control | Logic level sets increment/decrement direction of wiper movement on each INC edge |
| INC | Increment clock | Negative-edge-triggered; advances wiper one position per valid edge while CS = LOW |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ100 | I²C interface, dual-channel, 100 kΩ, 256-tap resolution, 2.7–5.5 V supply | Supports multi-device addressing and simultaneous channel updates; higher resolution but lacks nonvolatile store on power cycle | Select when I²C bus integration and dual independent pots are required; avoid if single-shot nonvolatile recall is mandatory |
| MCP41010-I/P | SPITM interface, 10 kΩ, 257-tap resolution, 2.7–5.5 V, volatile wiper register only | No built-in EEPROM; requires external memory or host MCU to retain settings across power cycles | Choose for cost-sensitive, high-resolution trimming where host firmware manages persistence; unsuitable for standalone power-up defaults |
Compared with AD5243BRMZ100 and MCP41010-I/P, the X9315TMZT1 trades higher tap count for guaranteed nonvolatile retention and simpler 3-wire control-making it optimal for single-pot, self-contained calibration where power-cycle repeatability is essential and I²C/SPI infrastructure is unavailable or undesired.

FAQ
What is the end-to-end resistance value and tolerance for X9315TMZT1?
The X9315TMZT1 has a nominal end-to-end resistance (RTOTAL) of 100 kΩ with a tolerance of ±20%, as specified in the Ordering Information table and confirmed in the Potentiometer Characteristics section. This value is fixed for the TMZ/TMZT1 variant family and applies across the full 0°C to +70°C operating range.
Does X9315TMZT1 support 2.7 V operation?
No, X9315TMZT1 does not support 2.7 V operation. Per the Ordering Information table, its VCC limits are 5 V ±10% (4.5 V to 5.5 V). The -2.7 suffix variants (e.g., X9315TMZ-2.7T1) are separate part numbers with different internal design and qualification; X9315TMZT1 is strictly a 5 V device.
How is wiper position stored and recalled in X9315TMZT1?
Wiper position is stored in nonvolatile memory when CS transitions HIGH while INC is held HIGH. Upon subsequent power-up, the X9315TMZT1 automatically recalls and applies that stored position to the wiper, ensuring consistent startup behavior without host intervention. This occurs regardless of U/D or INC state during power-on reset.
What package type and lead count does X9315TMZT1 use?
X9315TMZT1 uses an 8-lead Mini Small Outline Plastic (MSOP) package, Pb-free and RoHS-compliant, with JEDEC MO-187AA footprint (drawing M8.118). Its dimensions are 3.0 mm × 3.0 mm × 0.85 mm, and it features gull-wing leads compatible with standard reflow processes.
Can X9315TMZT1 be used as a two-terminal variable resistor?
Yes, X9315TMZT1 can be configured as a two-terminal variable resistor by connecting either RH/VH or RL/VL to RW/VW and using the remaining fixed terminal with the wiper. This configuration is explicitly supported in the Applications Information section and maintains full 32-tap resolution and nonvolatile storage functionality.
